Final Report Summary - SAND.CORe (Coordination Action on Advanced Sandwich Structures in the Transportation Industry)

The SAND.CORE project aimed to foster the application of innovative sandwich structures in the European transport, in particular the maritime sector. This was done by benchmarking, harmonising and complementing previous research work and evaluating state-of-the-art knowledge and experiences. The project produced a best practice handbook which will make research results and experiences more easily available to the European research community and industry.

The overall objective of the project was to boost the applications of sandwich structures in the rail and maritime transport sectors. The project aimed to collect structure and publish information from previous research and applications about sandwich panels, which was widespread over the industry and other parties (research, classification societies, suppliers, shipyards…). Therefore, there was a need to coordinate research, to conduct knowledge transfer and foster the application of various types of sandwich structures.

SAND.CORE achieved its objectives with a work plan, which was divided into coordination and management work packages. Coordination activities included the creation of a sandwich catalogue, the collection of available information on sandwich solutions as well as benchmarking studies. Various actors of different industrial sectors worked together in the project, thus creating a basis for future collaboration and exchange of information. Exploitation and dissemination activities, like a public website, a best practice handbook, a user group and several public workshops provided benefit to the consortium, industry, the educational system and the broader public.

The project was structured into five work packages (WPs), as follows:

WP 1: Available information in the field of sandwich structures has been analysed and knowledge has been exchanged between partners through three tasks: existing and future applications, technologies and knowledge, and rules and regulations. A harmonised knowledge and information on sandwich panels has been collected. In accordance with the European Commission services some gaps identified in the deliverable were filled during the extension period in the latest version of the best practice guideline.

WP 2: An internet communication platform has been developed and was made available at an early phase of the project under After having harmonised and standardised the different available results and information on sandwich, a methods catalogue, a solution selection tree and a test data catalogue have been developed. They can be found on the website. It has turned out in the cause of the work, that harmonisation of the design and test methods and impact on standardisation was difficult within the given consortium. It was therefore agreed with the project officer, that more efforts were put into the best practice handbook, which will give direct benefit to industrial users.

WP 3: Out of a list of potential cases, a list of five benchmarking cases has been selected jointly by the project partners: a wheel loaded strength deck of a RoRo ship, balconies for cruise ships, outer shell of superstructure for offshore patrol vessels, crash-worthy side structures and a rail vehicle cab shell. The purpose of the benchmark studies was to redesign existing practices using the available knowledge about various sandwich options and to compare / combine available solutions for the selected cases. Following a risk assessment, new design solutions of different sandwich applications have been performed for each benchmarking case. The work of these studies finished with a cost - benefit estimation of the sandwich solutions developed. Through the promotion of intensified practical application of sandwich structure new design solutions have been developed and optimised. Their costs and benefits have been evaluated.

WP 4: A best practice guide on sandwich structure has been created. The guide is structured into the three sandwich types most commonly used in the maritime and rail sectors: all-metal, hybrid-metal (a combination of metallic and non-metallic materials) and composites. The deliverable gives a comprehensive overview on current best practice (focused on the maritime field) on the general types of sandwich structures, design of sandwich structures, sandwich manufacturing, joining, assembly and outfitting, inspection and repair, legislation and approval as well as on application case studies. The document is primarily tailored to the needs of practical designers in industry, which have plenty of experience about the product they design, but lack an overview of best practice related to sandwich structures. It also provides links to further sources of information. In addition, future research needs have been discussed among the consortium and listed in an additional document.

WP 5: In order to disseminate the results and knowledge of the project and to make contact with other industries and projects, three workshops were organised during the project. In the same context, a user group with five members was initiated. The user group proved an efficient tool to exchange information with external parties and to discuss the views of the consortium with a wider community of experts. A promotional sandwich CD-ROM was created and distributed to the public of the meeting in Newcastle. This CD-ROM will be updated with the new best practice guideline elaborated during the extension period of the project.
