Final Report Summary - COALINE (Development of an innovative manufacturing process for the in-LINE COAting of pultruded composites)
The work carried out at the beginning of the project was related to the definition of the needs and requirements of the producers and end users of the coated pultruded demonstrators for the construction and automotive markets (16 mm rod for ACCIONA and a rectangular hollow shape for ALKÈ). Also, preliminary market analysis and the identification of the initial risk indicators for the project were done.
- The thermal parameters and dielectric properties were measured for the resins and coatings selected by the end users.
- The material selected for the microwave antenna system was ZrO2 and the microwave susceptors selected were: Polyethylene glycol 200 (PEG) and Diisononyl phthalate (DINP).
- The assessment about the suitability of the susceptors was checked by MW curing, the reduction of the curing time of the polyester and vinylester resin was more than 50%. Besides, the susceptors do not influence the mechanical properties of the resins (tensile strength and shore D hardness).
- Regarding task 2.5: the lap shear tests of the primer developed by RESCOLL shown that the primer is a substitute of the abrasion and degreasing steps (usually implemented for the bonding of pultruded composites). The curing time of this primer was reduced from 1h at 100°C to 90 seconds at 150ºC due to pultrusion requirements. The debondable two component adhesive was developed (thermal mechanism).
The holistic numerical simulation was developed (using an internal data-acquisition software) and the final design of the microwave antenna system and the pre-heater for ACCIONA´s and ALKÈ´s die was developed in order to be integrated into the pultrusion die. Both designs were tested and built.
- Development and testing of FEM procedures for the thermo-chemical simulation of pultrusion processes using ANSYS Mechanical and ANSYS CFX software. Development and testing of EXCEL tool for a building of the curing kinetic models using the results of DSC tests. Experimental validation of the developed algorithms using results of the conventional pultrusion of cylindrical rod (the profile is cured just after the ceramic part). Development of optimal design concept for a new technology of coating in-line a pultruded profile in a continuous process.
- A POLYMEC test mould was first used (as it had the same dimensions as the ACCIONA´s die) in order to achieve valuable information for the following design of the final die. After some version designs the final ones were obtained and the manufacture of both moulds were done.
- A new real-time cure prediction system has been developed and tested successfully. Curved Sensors have been developed.
The integration of all the COALINE subsystems were developed: each die with both injection machines, the two microwave heating systems, the sensing system (curved sensors for ACCIONA´s mould) and the reinforcement guidance system (more complicated for ALKÈ´s mould due to the high amount of fibers). Three different trials were necessary for the whole integration and the adjustment of the size of the die stages. During this WP, the profile was cured successfully using MWs. The integrated Data Acquisition System was developed: measurements of real-time temperature for the 4 heating zones together with the temperature at the Microwave heating area and the profile speed were displayed. Some trials were done to achieve the validation of the full COALINE process at pilot plant level.
Many different trials with both moulds were done and the coated ACCIONA´s rod was achieved. Both profiles (ACCIONA´s and ALKÈ´s) were tested (thermal characterization, porosity, mechanical behaviour and microstructure characterization). The debondable adhesive was tested obtaining very good results and a full cargo bed chassis was manufactured in ALKÈ´s facilities using primer coated profiles (supplied by POLYMEC, AIMPLAS and RESCOLL) and the adhesive developed by RESCOLL.
A technical and economic analysis has been doing throughout the project in WP7: the new process could be economically cost effective if the pulling speed is above 20 cm/min (for polyester matrix) and 25 cm/min (for epoxy matrix). Environmental study and regulatory analysis and safety issues has been also completed.
Dissemination and exploitation activities have been done along the project development in WP8.
Project Context and Objectives:
The aim of COALINE project is to develop an in-line clean one-stage process, which is free of VOCs and small particles emissions, able to produce properly coated composite pultruded profiles by means of the development and integration of the sensing technology, advanced die design and microwave aided curing needed to adjust the curing degree of the resin in each stage of the die, to foster an improved composite coating adhesion with a reduced labour and process cost. COALINE profiles will be joined to other materials by means of a primer type coating, incorporated also in-line, with debonding on-demand properties.
COALINE aims to address the production of valuable coated pultruded profiles by dramatically reducing their cost (up to 35%) and the number of processing steps, significantly increase output and improving their quality in comparison with coated pultruded profiles obtained nowadays. The main objectives in COALINE project are the following:
• Development of a model to predict the curing degree of the resin and coating as a function of the microwave generator parameters. The main objective is the achievement of a covalent bonding between composite and coating.
• To obtain the relationship between the shrinkage of the resin and its curing degree and temperature in order to properly design the coating injection chamber.
• To formulate the resin with the necessary microwave susceptors in order to properly increase its temperature to accelerate the polymerization in the pultrusion process.
• To ensure the safety of the microwave system in the pultrusion process by designing suitable radiation traps.
• To create a specific microwave antenna to be integrated into the pultrusion die in order to increase the temperature of the resin and gel coat and consequently trigger its polymerization.
• To develop a specific sensoring system to continuously monitor the curing degree of the resin and coating inside the pultrusion mould.
• To formulate a fast curing primer for coating the composite profile and foster the adhesion of a de-bondable adhesive.
• To obtain the design rules for the new dye configuration determining the injection points, section dimensions and other parameters in order to achieve the proper process performance (throughput, energy/cost efficiency).
• To integrate the developed sensors and MW radiation equipment in the die.
The COALINE workplan was focused on providing solutions to the real needs of the Industry regarding coated pultruded profiles: finding a true alternative to existing currently employed pultruded profiles which allow simultaneously a significant improvement of quality and cost.
Furthermore, an improved performance regarding the adhesion of the coating to the composite has been achieved by means of a controlled curing degree system integrated in each stage of the process. Thus, this would provide added value to the EU industry, increasing workers’ skills and consolidating employment, fully in line with the Europe 2020 strategy35, which highlights innovation as the key factor to overcome the strong competitive pressure from globalization.
The reduction of energy consumption in comparison with current coated profiles manufacturing has been in the order of at least 30% by the reduction of the number of processing steps and the use of alternative heating systems. Specifically, a microwave heating system has been developed in order to reduce the energy consumption and the polymerization time. In addition, a new range of modified resins with microwave susceptors have been developed to improve radiation absorption and reach a fast curing process.
Furthermore, VOCs and small particles emissions has been reduced at least 60% by directly injecting resin and coating inside the mould and avoiding post-manufacturing treatments of the composite surface. The labour conditions will be improved in terms of minimizing VOCs and small particles emissions. The developed process should also lead to a reduction of waste (sand) by at least 60%by direct injection systems and the potential of profile forming and coating in one step process.
Industrial partners have participated actively in the project decision making structure to ensure that the involved industrial sectors are the main drivers of the project activities and beneficiaries of the project results.
COALINE success has been mainly based on the strong interaction and partnership of SMEs/industry and research organizations highly skilled in complementary fields. The participation of end-users guarantees high impact and the wide dissemination & exploitation of the project results at National and EU level. The achievement of these results represents a significant advantage to the SME and End User participants demanding coated pultruded profiles for electric automotive (Partner ALKE) and urban infrastructure sectors (Partner ACCIONA).
The steps needed to achieve a major impact of project activities start with the careful execution of the proposed work plan and achievement of the project goals, demonstrating the COALINE positive environmental and economic impact, and continue ensuring the appropriate measures for the efficient dissemination of project results and the efficient transfer of the generated foreground to the EU industry, with particular focus to SMEs.

The project information has been disseminated via three channels:
a) By partners, within their organizations and with their clients/contacts (e.g. companies websites, newsletters, meetings, training courses, etc.)
b) By partners, during external events (e.g. fairs, conferences, exhibitions, workshops, etc.)
c) By partners, using media across Europe (e.g. press release, Internet, specialized/ sectorial magazines, etc.)
It is essential to highlight that a considerable number of dissemination activities have been completed during the development of the COALINE project, i.e. more than 100 communications made (considering the different press releases; publications on partners´ websites or any other website page; articles in magazines, newspapers, etc; technical articles and posters, scientific publications, different project flyers adapted to the partners´ business interests; project presentations to clients or any other audience, project videos); partners have attended different events (fairs, conferences, workshops, info-days, exhibitions).
The use of various channels and methods (written, face-to-face & online) assured an optimal contribution of coverage, visibility and most important- setting up the scene for better market acceptance in the near future.
The activities in the Dissemination Plan covers different audiences and channels depending on the type of information to be disseminated, in order to assure the success of the project from a strategic, environmental, technologic and economic direction based on COALINE approach.
Dissemination tools and activities were divided in two main groups:
a) Industrial level: For the industrial partners, the principal objectives are to obtain results that will increase their competitiveness and market opportunities and to show these results to any potential client, in order to have a wider commercial activity and increase the company benefits. Activities such as participation in fairs, seminars, exhibitions, press releases on the new potential products...are aiming these results.
b) Non-commercial level: The RTD and HE participants are more focussed in non-commercial promotion and scientific aspects of the work. Only non-confidential project results are susceptible of publication or dissemination in journals, web-sites, congresses, workshops, fairs and seminars.
The consortium is determined to continue the dissemination actions for the COALINE project after the end of the project, focused on both the commercial and scientific audience, as an essential pillar of their interest in continuing the project work (each partner in their specific business field), to move on in a possible future exploitation of the project knowledge (as detailed in the summary table further below).
Different Dissemination tools (marketing material) were prepared, such as:
-Maintenance of the Online portal – Website: http://www.coaline.eu
-Brochures, flyers, postcards, posters
-General presentation of the project
-Videoclips of the project results, and available on the project website.
-Demonstrators for the project (more simple samples and the final demo parts)
All these resources are available at the Public part of the website and were used and displayed in fairs and meetings.
Potential Impact and Exploitation
Project and its research work done or to be done in the future of the project was broken down into exploitable results. These were results, drawn from projects work, which have commercial and/or societal significance.
The selected results were characterised from a viewpoint which is exploitation only. This is the market / customer demand or societal needs / user point of view. The following aspects were considered:
- Customer detection (focus on factors that affect purchasing decisions)
- Features of the target market (size, growth rate, share that the technology/product could reach, driving factors likely to change the market, legal, technical and commercial barriers, and other technologies likely to emerge in the near future...)
- Positioning (how the company entitled to the technology exploitation is positioned or should be positioned in the market).
List of Exploitable Results:
1. New blends (resins and coatings) with microwave susceptors;
2. Moulds for in-line coating pultrusion process with MW curing;
3. Primer and adhesive with de-bonding properties.
4. Curved sensors for controlling and monitoring the process.
Each result was then assessed in terms of risks connected to exploitation:
Non-technical factors which could represent potential risks and obstacles which could lead to the fact that the selected results of the project would remain unexploited. These factors could be of internal origin, such as partners’ diverging expectations or changing interests over the project’s life (risk of conflicts of interest), etc. Furthermore, these factors could be external, such as upcoming competition, changing market trends, etc.
The risks were analysed in terms of mitigation actions and effectiveness of interventions.
Another remarkable aspect of the Project Impact, is to have known what mainly partners obtained from the project and what they expect in the future, thanks to COALINE participation.

Therefore, based on the information given above, COALINE innovative technologies will open new potential markets for the traditional pultrusion composite companies in Europe.
True industrial impact will require further investment, mainly aimed to optimize:
a) The industrial production of the COALINE profiles (both for the building and automotive sectors);
b) the use of those microwaves equipment at scale-up level, making them suitable for a complete automatization process in the case of both sectors;
Although the project development is aimed at specific sectors (automotive and building equipment, as was agreed under Annex I of the project), the technologies developed will be able to be applied to other type of sectors, where composite materials are currently used, or are susceptible of being used (sanitary sector, naval industry,
etc.), provided that the specific requirements of each final product can be fulfilled/adjusted from the starting characteristics.
All the above-mentioned sectors could be additional business for the SMEs involved in the value chain (compounders, mould manufacturers, end-users/distributors). The owners of the different results defined in the final version of the Plan for the Use and Dissemination of the Foreground will take into account these new niche market sectors.
To sum up, the consortium strongly believe that there is a true potential for this novel technology to replace a part of the existing pultrusion business and are committed to pursue this road along with any other company that may become interested in exploring such ground.
There are certainly many challenges and obstacles to be surpassed but it is COALINE consortium duty to expand the boundaries of the described technology.
