摘要

To understand the quasi-static and dynamic compressive mechanical behavior of two-dimensional SiC fiber-reinforced SiC composites (2D-SiC_f/SiC), their compressive behavior at room temperature was investigated at a strain rate from 10⁻⁴ to 10⁴ /s, and the fracture surfaces and damage morphology were observed. The results show that the dynamic failure strength of 2D-SiC_f/SiC obeys the Weibull distribution, and the Weibull modulus is 5.66. Meanwhile, 2D-SiC_f/SiC presents a transition from brittle to tough with a decrease of strain rate, and 2D-SiC_f/SiC has a more significant strain rate sensitivity compared to the 2D-C/SiC composites. The failure mode of 2D-SiC_f/SiC depends upon the strain rate.
