Short-fibre Reinforced Thermoplastic for Semi-structural Parts: Process-properties

Abstract : This work concerns the high pressure injection of semi structural polymer-short fibre reinforced-parts. A research group, with three aeronautic firms of Toulouse and two academic laboratories of the French Midi-Pyrenees Region, intends to deal with these whole problems from the manufacturing process to the structural analysis of the injected parts. More particularly, this work features the interfacing of the industrial computation tools of fibres orientation and mechanical response of structures. Starting from the orientation data, the computation and the localization of the distributions of homogeneous elastic properties are performed for three industrial parts respectively a body of aircraft pressure valve (Liebherr Aerospace), a first stage stator (Microturbo) and a fan wheel (Technofan).
