Abstract
The fiber/matrix interaction of fiber reinforced composites is important in determining the mechanical behavior of the composites. To examine the effects of loading rate and fiber coating on the interfacial strength of ceramic/ceramic composite, we tried single fiber pull-out test and microbond test. SiC fibers with BN coating and without coating are used. They are embedded in inorganic adhesive. The interfacial shear strength of the specimen using BN coated fiber is smaller than that of the non-coating fiber. The critical load required to pull the fiber out without breaking it decreases, when the loading rate is larger. In the range from 0.1N/min to 2.5N/min, the effect of the loading rate does not appear for the average interfacial shear strength.
