Curing of Thick Angle-Bend Thermoset Composite Part: Curing Cycle Effect on Thickness and Fiber Volume Fraction Variation

摘要

In this paper, the effect of cure cycle on the quality of angle-bend thermoset parts is presented. A 2-D finite difference scheme was used to model the processing of arbitrary shaped composite laminates. This model includes heat transfer, viscosity, rate of cure, and resin flow submodels. Experiments were done to investigate the effect of different curing cycles on thickness variation and fiber volume fraction distribution. Results were obtained from both simulation and experiment.
