An engineer needs design allowable and predicting models to design structures and plan the manufacturing process. For resin transfer moulding (RTM) of fibre-reinforced plastic (FRP) structures the mould design and flow-strategy is based on experience and trial and error. Finite element tools are available to predict resin flow. But, accurate input-data in the predicting model is essential. A large problem is formed by the lack of permeability numbers for high fibre contents (50% - 60%). At the moment the RTM-process of products with relatively thick (t > 2 mm)laminates and low fibre volume fractions (15% - 25%) has rejection rates of less then 5%. Rejection rates of more then 50% can be found in products with a laminate thickness of 0.5 mm and a fibre volume fraction of 50%. The main project objective is to determine the design allowable for RM of thin-walled (0.5 - 1 mm) CFRP structures at fibre volume fractions (50% - 60%),resulting in rejection rates of 5%.
