顶出法对细编穿刺碳/碳复合材料界面强度的研究

Study of Interfacial Shear Strength on Fine Weave Pierced Carbon/Carbon Composite by Push-out Test

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，

A push out test system was build and the interfacial shear strengths of the carbon/carbon composites made from different processes were checked by pushing the single carbon fiber out of the matrix. The relationship between the interacial shear strength and the tensile strength was also studied through the push out test.
