Title: A novel crystallization kinetics model of transcrystalline used for crystallization behavior simulation of short carbon fiber‐reinforced polymer composites

Abstract

A combined model is presented to simulate the crystallization behavior of short carbon fiber‐reinforced polymer (SCFRP) composites in this work. The combined model accounts for two morphologies in SCFRP: transcrystalline and spherulite. Transcrystalline is affected by complicated processing conditions and fibers and significantly affects the performance of composites. The quantitative modeling of crystallization kinetics of transcrystalline is thus important in predicting the mechanical properties of the composites. Therefore, this work proposes a novel analytical crystallization kinetics model of transcrystalline for SCFRP. In the combined model, the crystallization kinetics of spherulites is calculated using a classic Kolmogorov model. The combined model for SCFRP is first validated using a pixel coloring method in a two‐dimensional (2D) simulation experiment and is then compared with the results of a differential scanning calorimeter (DSC) experiment. The results of the model and experiments (using pixel coloring method and DSC) were found to be in agreement, which proves the rationality of the combined model. The modeling results also show that transcrystalline can accelerate the crystallization rate of composites, and the acceleration effect is more remarkable at high temperature. The proposed crystallization kinetics model has good potential for modelling the crystallization behavior of SCFRP under complex processing conditions.more » POLYM. ENG.
