OBSERVATIONS OF STRESS AND LAMINATE THICKNESS VARIATIONS IN LCM PROCESSES
Résumé
Closed moulding processes are increasingly being used for the manufacture of fibre reinforced thermosets. A variety of mould construction methods and filling techniques are used, producing an ever expanding list of processes within the Liquid Composite Moulding (LCM) family. The long term goal of this research programme is the development of a generic LCM filling simulation, able to address processes utilising rigid, semi-rigid, and flexible moulds. This paper highlights recent developments in the experimental verification programme. A Tekscan dynamic pressure measurement system has been used to measure normal stresses exerted on a rigid mould during RTM and ICM cycles. A stereophotogrammetry technique has been employed to measure full field laminate thickness variations during Resin Infusion. Discussion is provided on initial results obtained with these systems.
