研制了一套表征碳／碳（Ｃ／Ｃ） 复合材料界面力学性能的单丝顶出测试系统， 实现了对碳纤维的单丝顶出测试。利用该仪器测定了不同工艺条件下制备的几组Ｃ／Ｃ复合材料样品的界面粘接性能， 研究了界面剪切强度和复合材料拉伸强度之间的关系
A monofilament ejection test system was developed to characterize the mechanical properties of the carbon / carbon (C / C) composite interface. The monofilament ejection test of carbon fiber was achieved. The interfacial adhesion properties of several C / C composites prepared under different technological conditions were measured by the instrument. The relationship between the interfacial shear strength and the tensile strength of the composites was studied
