对三种炭纤维和三种酚醛树脂进行了六种二维层合炭 /炭复合材料研制 ,测试了层间剪切强度和拉伸强度。 TCF/ FB体系、RCF/ RPh体系所制备的二维 C/ C具有较高的层间剪切强度和拉伸强度 ,层间剪切强度在 1 6MPa以上。分析表明 ,二维炭 /炭中纤维 -树脂体系存在一个最佳配合问题 ;纤维表面的官能团比表面粗糙度在界面连接上起更重要的作用 ;树脂的选择还要结合其结构来进行 Six kinds of two-dimensional laminated carbon / carbon composites were fabricated on three kinds of carbon fiber and three kinds of phenolic resin. The interlaminar shear strength and tensile strength were tested. TCF / FB system, RCF / RPh system prepared by two-dimensional C / C has a higher interlaminar shear strength and tensile strength, interlaminar shear strength of 16MPa or more. The analysis shows that there is an optimal combination of fiber-resin system in two-dimensional carbon / carbon; the functional groups on the surface of the fiber play a more important role than the surface roughness in the interfacial connection; and the selection of the resin should be carried out in combination with its structure
