摘要：

The effect of two different fibre architectures on the mechanical properties of the Nicalon fibre-reinforced SiC composites processed by chemical vapour infiltration has been investigated. The microstructure, flexural strength, fracture toughness and failure mechanisms of both two-dimensional woven laminate and three-dimensional braided composites were characterized. It was found that the fibre placement in the preform will not only affect the infiltration of the SiC matrix, but also the mechanical property and failure behaviour of the composite. A strong, tough and damage-tolerant SiC matrix composite can be fabricated through the combination of a three-dimensional braided integrated fibre network and chemical vapour infiltration processing.
