Development of Conventional protrusion test equipment for measuring interface mechanical properties in fiber-reinforced composites

研制了一种新型的修道院离子化凸度试验装置。该装置可以测量纤维增强复合材料界面剪切滑动阻力，而不会因测量纤维伸出长度而产生人为误差。通过模型试验研究了纤维伸出长度与界面脱粘/滑移长度的关系。W纤维增强环氧树脂基复合材料被用作模型复合材料。根据模型实验的结果确定了实验条件。采用Proximity法测量了SiC纤维增强玻璃陶瓷复合材料的界面剪切滑动阻力，测量温度范围为室温~ 773 K，并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，所开发的设备被用作纤维增强复合材料界面力学性能的常规测量设备。

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.
