A Crystallization Kinetic Model for Long Fiber-Based Composite with Thermoplastic Semicrystalline Polymer Matrix

A numerical model is presented to simulate the crystallization kinetics in fiber-based composite with thermoplastic semicrystalline matrix. The proposed model, based on Schneider's formalism, considers specificity of crystalline entities growing confined medium such as fibrous composite. Indeed, transcrystallization has been experimentally observed many times and its effects both mechanical properties have largely demonstrated. As an application, this paper aims at illustrating former effect a finite element (FE) simulation cooling down plate. simulated materials are polypropylene alone Information temperature, rate transformation microstructure obtained from compared emphasize contribution transcrystallization.
