摘要

以炭纤维无纬布/网胎针刺整体毡为增强体,先采用化学气相渗透法(chemical vapor infiltration, CVI)沉积热解炭制备C/C多孔体,之后使用CVI沉积SiC和压力熔渗Cu制备C/C-SiC-Cu复合材料。研究C/C多孔体密度和SiC含量(体积分数φ,下同)对C/C-SiC-Cu复合材料弯曲性能的影响。结果表明,随着C/C多孔体密度和SiC含量增加,热解炭和SiC在炭纤维周围形成具有较高结合强度的界面,二者的增强作用得以充分发挥,C/C-SiC-Cu复合材料的抗弯强度显著增加。弯曲断裂时,热解炭和SiC基体对炭纤维的拔出有抑制作用,C/C-SiC-Cu复合材料的载荷-位移曲线呈起伏台阶式下降,表现出明显的假塑性断裂特征。

Abstract

Using carbon non-woven fabric/fibre web as the reinforcements, porous C/C composites were prepared by chemical vapor infiltration (CVI) deposition of pyrolytic carbon, and then SiC was deposited by CVI and Cu was infiltrated under pressure successively. Fianlly, C/C-SiC-Cu composites were obained. The effects of density of porous C/C composites and SiC contents (volume fraction φ, the same below) on the flexural property of C/C-SiC-Cu composites were investigated, respectively. The results show that with the increase of porous C/C composites density and SiC content, pyrolytic carbon and SiC form an interface with high binding strength around carbon fibers, and the strengthening effect of them can be fully played. So the flexural strength of C/C-SiC-Cu composites significantly increase. When the bending process is carried out, pyrolytic carbon and SiC matrix can inhibit the pullout of carbon fibers. The flexural load-displacement curve of C/C-SiC-Cu composites is ups and downs step-like, showing obvious characteristics of pseudoplastic fracture.
