摘要

孔隙是复材构件中不可避免但又对结构强度影响非常重大的缺陷。采用共固化及真空袋– 热压罐成型方法制备了蜂窝夹层复材构件，研究了不同预压实工艺参数对蜂窝夹层复材构件变厚层压区域孔隙率的影响。通过改变预压实真空度、预压实时间及预压实辅助材料组合方式进行对比试验得出：提高预压实真空度、适当延长预压实时间及采用有孔隔离膜A4000RP3+ 透气毡Style PC3 的预压实辅助材料组合方式，可以起到降低复材构件变厚层压区域孔隙率作用。

Abstract

Porosity is one of the most unavoidable defects in composite part which has significant impact on structural strength. The sandwich structural composite parts were manufactured by vacuum bag-autoclave co-curing method. Porosity of sandwich composite part laminated area with variable thickness was studied by adjusting compaction parameters including compaction vacuum

compaction time and ancillary material types. Results show that improving compaction vacuum

extending compaction time appropriately and using perforated release film A4000RP3 and breather Style PC3 can reduce the porosity of composite part variable thickness area.
