Abstract :
Single crystal SiC nanowires with volume fractions of 0%, 1.6%, 5.7% and 6.1% were incorporated in the matrices of several CVI-Tyranno-SA/SiC composites, to study the effects of the nanowires on the flexural properties of the composites. The results show that the SiC nanowires are very effective reinforcements for SiC/SiC composites. The flexural modulus, proportional limit stress and ultimate strength increase linearly with the increasing nanowires volume fraction. Specifically, the flexural properties depend on the thickness of carbon coating on the nanowires.
