Longitudinal compressive behavior and failure mechanism of three-dimensional five-directional carbon/phenolic braided composites at high strain rates

The uniaxial compressive stress–strain response of three-dimensional (3D) five-directional carbon/phenolic braided composites are experimentally investigated at high strain rates from 350 to 1600 s−1 using the split Hopkinson pressure bar technique. The compressive loads are applied in a longitudinal direction (along the braiding direction). The macro- and micro-fracture morphology examinations are conducted using a scanning electron microscope...
