摘要/Abstract

摘要： 通过试验研究了一种非热压罐(Out of Autoclave,简称OOA)预浸料T700SC/#2510层压板的低速冲击损伤特性。针对三种典型铺层方案,获得了层压板的凹坑深度-单位厚度冲击能量(d-e)、损伤面积-单位厚度冲击能量(S-e)和冲击后压缩强度-凹坑深度(σ-d)曲线,以及三个批次的该OOA预浸料准各向同性层压板在标准冲击能量6.7J/mm下的剩余压缩强度结果。结果表明,T700SC/#2510材料体系冲击表面损伤不明显,但内部损伤却较大;该OOA预浸料的d-e曲线、S-e曲线和σ-d曲线均存在拐点现象;准各向同性铺层可以吸收更高的冲击能量,但也导致了更大的内部分层损伤;该OOA预浸料的CAI强度满足第二代OOA预浸料的指标。

Abstract: The document tested the low-velocity impact performances (damage resistance and damage tolerance) of an Out of Autoclave (OOA) prepreg composite systems T700SC/#2510. The relationship curves between dent depth and impact energy per thickness millimeter (d-e), damage area and impact energy per thickness millimeter (S-e), compression strength after impact and notch depth (σ-d) are obtained with three kinds of classic layup. And the compression strength after impact with 6.7J/mm energy of three batches of this OOA prepreg quasi-isotropic laminates is also obtained. The results show that, the damage on the impact surface of the composite systems T700SC/#2510 is barely visible, but the internal damage area is very big. There is an inflexion in all the relationship curves of d-e, S-e and σ-d. The quasi-isotropic layup can absorb more impact energy, but results in a larger delaminating damage area. The CAI strength of this OOA prepreg quasi-isotropic has approached the target of the second generation OOA prepreg.

Key words: out of autoclave (OOA) prepreg, carbon fiber/epoxy, low-velocity impact performance, compression after impact
