Curing Process Modeling of Z-pinned CFRP Composites
摘要
Curing process after Z-pinning insertion becomes one of the essential issues affecting the enhancement of Z-pins. When Z-pinned prepreg laminates undergo elevated temperature and pressure loads in autoclave, residual stresses are gradually generated, which are attributed to thermal expansion and chemical shrinkage mismatch between different phases in the microstructure.
