Abstract
The compressive properties and compressive failure mode of multi-layer carbon woven/epoxy resin composites with various carbon nanotube (CNT) contents at quasi-static and high strain rates loading have been investigated in the present paper. The results indicate that the stress–strain curves are strain rate sensitive, and the compressive stiffness and compressive failure stress of composites with various CNT contents are significantly influenced by the strain rates and CNT content. The compressive failure modes of woven composites without CNTs tend to be in shear deformation, delamination fiber breakage and matrix cracking, and the failure modes of woven composites with higher CNT contents are mainly delamination, matrix cracking and shear deformation.
