| 摘 要： | 本文研究了碳布增强的聚芳醚酮复合材料的破坏允限。用二碘甲烷增强的x-射线照相法对试件内部的冲击缺陷进行观察,结果表明,其破坏类型可分为分层、基体开裂、纤维断裂和脱胶。用三点弯曲方法测定了损伤试件的剩余弯曲强度与冲击能量的关系。

| Abstract: | Damage tolerance of woven carbon fiber reinforced poly(phenylene ether ketone)(woven CF/PEK-C) laminates has been studied on bending after falling-weight impact.Woven CF/PEK-C laminates were obtained by stacking PEK-C films with carbon cloth andthen consolidating at temperature above T_g of PEK-C. The penetrant-enhanced x-radiogra-phy was used to determine the locations and extents of delaminations and matrix crackscaused by impact. It is shown that the damage mode of woven CF/PEK-C can be classifiedinto delamination, matrix crack, fiber breakage and debonding between fibers and thematrix. The residual flexural strength of a damaged laminate for the highest impact energywas about 50% of that before damaging. |
