| Research Abstract |
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.
