An Experimental and Numerical Study on the Impact Energy Absorption Characteristics of the Multiaxial Warp Knitted (MWK) Reinforced Composites

In this paper, an experimental and numerical study on the energy absorption characteristics due to the low-velocity impact of the composites reinforced by the multiaxial warp knitted (MWK) structures with double loop pillar stitch and common tricot stitch are presented. The influences of the MWK structural parameters on the impact behavior and energy absorption properties are discussed. A good agreement between the experimental results and simulation is obtained.
