Production and processing of thermoplastic based towpregs for commercial and advanced markets

Abstract

In this work continuous fibre reinforced thermoplastic matrix towpregs were produced for commercial markets and advanced markets. The former based on glass fibre reinforced polypropylene matrix (GF/PP) and the latter on carbon fibre Primospire® matrix (CF/P). Primospire® is an amorphous highly aromatic material specifically developed by Solvay Advanced Polymers for application in advanced markets. Both towpregs were processed into composite parts by different technologies. The mechanical properties determined on the final composites were compared with the theoretical predictions and have shown to be acceptable for the targeted markets.
