摘要：

The effects of fiber composition, size, and surface treatment on the mechanical behavior of slip-cast fused-silica composites were investigated. The ambient and 1000-degrees-C stiffness and strength, fracture toughness, G(R)-curve behavior, and fiber-matrix interface bond strength were determined. Quantitative fractography and scanning electron microscopy were used to ascertain the mechanisms of toughening and strengthening. Composites with weak interface bonding exhibited good strength retention and rising G(R)-curve behavior. The fracture resistance was improved primarily through crack deflection.
