ABSTRACT

The implementation processes of thermoplastic composites directly depend on the commercial presentation of the CLFT composites (continuous fiber composites) and the existing transformation processes for reinforced thermosetting composites and SFT( Short Fiber Thermoplastic) composites. The objective of the transformation of a CLFT (Continuous Long Fiber Thermoplastic) into a manufactured object is to preserve the continuity of the fibrous reinforcement whilst maintaining the full reinforcing effect of the fiber and minimizing shear stresses on the processed material.

 INTRODUCTION

The processing of thermoplastic composites is directly dependent on the commercial presentation of CLFT composites (continuous fiber composites) and on the existing transformation processes for TDA (reinforced thermoset) and SFT (short fiber thermoplastic) composites in small, medium and large production runs.

The aim of transforming a CLFT (Continuous Long Fiber Thermoplastic) into a manufactured object is to preserve the continuity of the fibrous reinforcement, while retaining the full reinforcing effect of the fiber right through to the part by minimizing shear forces on the transformation material (use guiding and friction systems with a roughness of less than 1 µm and a sliding coefficient close to that of polished ceramic or 800-polished brass alloy).
