摘要: Abstract In this paper, the tensile behavior of carbon fiber reinforced aluminum laminates (CRALL) has been determined at a strain rate range from 0.001 s − 1 to 1200 s . Experimental results show that CRALL composite is sensitive material, and strength failure both increased with increasing rate. A linear hardening model combined Weibull distribution function establish constitutive equation for different rates. The analysis shows scale parameter, σ 0 , rate, but shape β can be regarded as constant.
