讨论了碳纳米纤维（CNF）对CNF增强C/C复合材料的弯曲性能和层间剪切强度的影响。结果表明，含有5wt.%CNFs的复合材料的弯曲强度、模量和层间剪切强度比不含CNFs的复合材料分别提高了近21.5%、33.5%和40.7%。当添加剂含量增加到20wt.%时，由于CNF网中以及碳布与基体之间的孔洞和空腔，弯曲性能和层间剪切强度均从添加剂含量为5wt.%时的最大值下降。
The effects of carbon nanofibers (CNFs) on the flexural properties and interlaminar shear strength of CNF-reinforced C/C composites are discussed. The results show that the flexural strength, modulus and interlaminar shear strength of the composite containing 5wt.% CNFs are increased by nearly 21.5%, 33.5% and 40.7%, respectively, compared to that of the composite containing no CNFs. When the additive content is increased to 20wt.%, due to the holes and cavities in the CNF web and between carbon cloth and matrix, both the flexural properties and interlaminar shear strength decrease from the maximum value with the additive content at 5wt.%.
