A quantitative comparison of experimental and numerical orientation and mechanical results in meldlines of short fibre reinforced thermoplastics
Résumé
Complex injection moulded parts often present some structural defects, like weldlines or meldlines. For short glass fibre reinforced thermoplastics, these defects strongly affect the mechanical properties of the parts. This project is a collaboration between two laboratories (CROMeP : Material Research Centre of Ecole des Mines d'Albi, PRO²COM-LGMT : Toulouse Mechanical Laboratory) and three companies (Technofan, Microturbo, Liebherr Aerospace). We calculate, using Moldflow® MPI 2.0 software, the fibre orientations in the meldline region. This allows us to evaluate the mechanical properties of the part. This study is realised using an ISO specimen geometry, with a volume deviation channel. Then, calculated orientations and mechanical results are compared to experimental data (based on SEM observations and mechanical testing) using a Krigging interpolation method.
