Abstract

Abstract

In order to obtain mechanical properties of phenolic cotton fabric material at different strain rates, we performed experiments of the uniaxial compression tests of phenolic cotton fabric material at the strain rate ranging from 10^-3 to 10³ s^-1, using the universal testing machine and the split Hopkinson pressure bar (SHPB), obtained the stress-strain curve at different strain rates, and discussed compression failure mechanism under quasi-static and dynamic loads. The results from our experiments show that the dynamic compression fail strength of phenolic cotton fabric material has strong strain rate sensitivity and it increases along with the strain rate. Compared with the stress under the quasi-static loading, the peak stress under the dynamic loading increases by approximately 10 times, while the failure strain is reduced to about half. The differences in the mechanical properties under quasi-static and dynamic loading conditions is due to the strain rate effect of the fiber matrix interface characteristics on the one hand, and to the differences in failure modes at different strain rates on the other. Zhu-Wang-Tang (ZWT) constitutive was adopted to describe the mechanical behavior of the phenolic cotton fabric material.
