Objective
The following results are obtained:
* A method for measuring in-mould permeability has been identified and has been proven feasible.
* Calculation methods have been determined to determine resin viscosity and geltime.
* A method for finding and determining leakages has been identified and has been proven feasible.
* Measurement methods and equipment has been determined and selected for registration of process parameters.
* Software has been developed which connect the individual measurements and stores the process parameters.
* Prototypes have been assembled and have been used by the SME's during production.
The European composites industry needs to change towards closed mould production techniques in order to comply to new environmental regulations and to improve the quality and quality consistency of their products. At the moment closed mould injection Techniques (Resin Transfer Moulding; RTM) have been successfully applied for small products in large series. Although usually the first 5 or 10 products are production failures and are rejected. for large series this investment is worthwhile. This has proven the advantages of a closed mould injection technique (better working conditions. less styrene emission and better quality products). The closed mould production of large parts can be practised using a vacuum injection technique. Due to the smaller series a failure of the first (or more) products is not acceptable. The mayor processing parameters like local permeability of the reinforcement. prevention of air leakage and resin cure behaviour (gel thee) are not controlled nor checked resulting in frequent product rejections. Therefore. there is a strong need for processing control tools which will ensure a successful vacuum injection. The final objective of the project is to develop dedicated processing control tools for vacuum injection. This goal can be achieved in three steps: . Ensure the measurement of all relevant process parameters . Interpretation of the measurements . Making the system applicable on the working spot in a company Main parts can be further defined: Measuring flowability (permeability) parameters in the mould (currently not measurable on the work spot) with a required accuracy to be able to distinguish between which differ by a factor I () (to be able to identify runner channels or blocked channels A smart database to aid the selection and control of resin (and/or gelcoat) formulations. Based on temperature. viscosity and formulation data this tool must be able to predict a geltime with an accuracy within 5 15 minutes. . Making the system applicable on the work spot. This implies that it is easy to operate and will give ready to use information for an operator: start the injection or not i.e. a green light indicating proceed with injection or a red light indicating stop or a yellow light indicating critical and indicating where a possible production error can be found. The project consists of different parts with different levels of risk. The measurement equipment for permeability differences and the clever software are the parts of the project with highest risk. With respect to the measurement of permeability differences the project will focus on two distinctive possible methods. (ultrasonic thickness measurements and laminar air flow measurements). After successful project completion the following goals related to the quality and quality consistency of the production can be realised: . 90 % of the first product made must comply to the specifications (this is currently approximately 50 %) . 98 % of each successive product must be made according to the specifications (this is currently 90 %) Cycle time must be decreased by 20 %. This can be achieved by further production optimisation allowing a better match of resin geltime with injection time resulting in quicker demoulding and decrease in cycle time.
