研究了单丝界面和纤维束界面结构在细编穿刺Ｃ／Ｃ复合材料制备过程中的演化规律以及两种界面剪切强度随着生产周期增加的不同变化趋势在 Ｃ／Ｃ的制备过程中单丝界面和纤维束界面的形成速度不同，单丝界面优先得到完善，经过四个周期界面剪切强度既可达到最高水平；而束界面剪切强度在六个周期后才达到较高水平
The evolution of monofilament interface and fiber bundle interfacial structure during the preparation of fine-grained punctured C / C composites and the different trends of interfacial shear strength with the increase of production cycle were studied during the preparation of C / C The formation speed of silk interface and fiber bundle interface is different, the monofilament interface is preferentially improved, and the shear strength can reach the highest level after four cycles, while the shear strength of bundle interface reaches a higher level after six cycles
