A new convent ional equipment for protrusion test has been developed. The equipment allowed measurement of interface shear sliding resistance in fiber-reinforced composite without artificial errors which due to measuring fiber protrusion length. Model experiments were carried out to examine relationship between protruded fiber length and interfacial debonding/sliding length. W fiberreinforced epoxy matrix composite was used as a model composite. Experimental conditions were determined from the results of the model experiment. Protrusion method was applied for the measurement of interfacial shear sliding resistance in SiC fiber-reinforced glass ceramic composites ; the temperature rage was from room temperature to 773 K.The temperature dependence of interfacial shear sliding resistance was discussed with theoretical analysis. The results clearly demonstrated that the developed equipment was used as conventional measuring equipment for interface mechanical properties in fiber-reinforced composite materials.

开发了一种新型常规突起测试设备。该设备可以测量纤维增强复合材料中的界面剪切滑动阻力，而不会因测量纤维突出长度而产生人为误差。进行模型实验来检查突出纤维长度与界面脱粘/滑动长度之间的关系。 W纤维增强环氧树脂基复合材料被用作模型复合材料。实验条件根据模型实验的结果确定。采用投影法测量SiC纤维增强玻璃陶瓷复合材料界面剪切滑动阻力；温度范围为室温至773 K。通过理论分析讨论了界面剪切滑动阻力的温度依赖性。结果清楚地表明，所开发的设备可用作纤维增强复合材料界面力学性能的常规测量设备。
