New PVC Matrix Towpregs and Composites
A cost efficient powder coating technology developed in previous work [1-3] was modified to produce glass fibre/polyvinyl chloride (GF/PVC) towpregs that were subsequently processed by compression moulding and filament winding. The production of GF/PVC towpregs was optimized and a process window established. The composite structures obtained were submitted to mechanical testing and the results compared with the theoretical predictions made using the classical laminate theory (CLT). The obtained results showed that the GF/PVC composites properties are compatible with all major engineering applications.
