The Effect of Zinced Sheet on Residual Stress of Composite Material with TPO During Cure Process

Abstract

Based on the indirect thermalâ€stress coupled strategy that the first analysis was temperature field and the second analysis was stress field, the process induced residual stress/strain of composite parts with zinced steel and TPO was numerical simulated by ANSYS software. Moreover, the role of zinced steel played on composite material part was successfully simulated. The results show that the time of maximum stress occurred for two materials was changed due to the effect of zinced steel. Because of the constrain from zinced steel, composite material part bearded more residual stresses compared to that without considering the effect of zinced steel during cure process.
