Abstract
The high strain rate compressive properties of UHMWPE interlaced biaxial weft knitted (IBWK) fabrics/vinyl ester resin composites were carried out in split Hopkinson pressure bar (SHPB). The strain rate effect and energy absorption of composites were studied. The results indicate that the compressive performances of composites are improved after plasma modification, and 100 W is an appropriate treating condition for discharge power. UHMWPE IBWK composite is a strain rate sensitive material in a certain extent: The peak stress, compressive modulus and specific fracture strain energy density increase with the increase of strain rate. Attribute to the knitted loop and the intertexture of warp and weft yarns, IBWK structure shows good impact resistance.
