Influence of some technological parameters on the content of voids on the in‑situ thermoplastic composites in Pultrusion, FW and AFP/ATP technologies

The manufacturing processes, such as pultrusion, filament winding and automated fiber/tape placement, have been used conventionally for thermoset composites. The automated processes can be adapted to include in situ consolidation for the fabrication of thermoplastic composites. In this paper, a detailed review of the factors affecting the in-situ consolidation process is presented for each technology in detail. Experimental tests were performed with changing parameters for the three technologies in order to minimize voids for the fabrication of thermoplastic composites. Optimizing these parameters ensures high-quality composite parts with superior mechanical properties who to be used in many applications.
