碳纤维增强碳（Ｃ／Ｃ）复合材料是由沥青基碳纤维粗纱编织的多层织物和煤沥青基体构成的， 本次实验研究了两种Ｃ／Ｃ多层织物复合材料和一种平纹编织Ｃ／Ｃ布复合材料，测试了弯曲、剪切和压 缩强度。根据不同跨距一高度比下的三点弯曲试验结果，表明Ｃ／Ｃ１多层织物复合材料具有高的剪切性 能，多层织物复合材料的分层断裂比平纹编织Ｃ／Ｃ布复合材料具有更高的层间断裂韧性。
Carbon fiber reinforced carbon (C / C) composites are composed of multi-layer woven fabric of pitch-based carbon fiber roving and coal tar pitch matrix. The experimental study of two C / C multi-layer fabric composites and a plain weave C / C cloth composites, tested bending, shear and compressive strength. According to the results of three-point bending test under different span-to-height ratios, the C / C1 multi-layer fabric composites have high shear properties. The multi-layer fabric composites have more layered delamination than the plain weave C / C fabric composites Higher interlaminar fracture toughness.
