Processing and quality of continuous fiber reinforced thermoplastic by direct extrusion
Thermoplastic sheets with continuous fabric or roving reinforcement offer the possibility of short cycle times. Conventional production solutions require double belt presses processing semi-manufactured plastic sheets or powders. An improvement of continuous fiber reinforced thermoplastic (CFRT) sheet production can be achieved through reduced energy consumption, increased output, improved impregnation and waste reduction. This work presents a high potential process applying a direct extrusion technology. It enables the impregnation and consolidation of woven textiles in an extrusion die with continuous throughput. A novel production line was developed and investigated for process capability. This extrusion process allows the production of CFRT sheet starting from thermoplastic granulate and woven textile in one single production line integrating plasticization, impregnation and sheet forming.
