通过对石墨复合材料圆管的静态压溃试验，研究了纤维和基体最大破坏应变对石墨复合材料吸能性能的影响。纤维和基质的最大应变在故障被确定为显着影响能量吸收。与AS-4/934、T300/5245或T300/934复合材料相比，较高的失效应变复合材料系统AS-4/5245表现出上级能量吸收能力。这项调查的结果表明，要实现最大的能量从复合材料的基体材料，具有更高的应变在故障比纤维增强应使用。
Static crushing tests were conducted on graphite composite tubes to examine the in fluence of fiber and matrix maximum strain at failure on the energy absorption capability of graphite reinforced composite material. Fiber and matrix maximum strain at failure were determined to significantly effect energy absorption. The higher strain at failure composite material system, AS-4/5245, exhibited superior energy absorption capability compared to AS-4/934, T300/5245 or T300/934 composite material. Results of this in vestigation suggest that to achieve maximum energy from a composite material a matrix material that has a higher strain at failure than the fiber reinforcement should be used.
