| Abstract: | The paper carried out an experimental study of stitching reinforcement for composite laminates with holes. The damage to stitching parameters such as stitching needle distance, row space, edge distance, single stitching or double stitching to the composite laminates was tested. The influence of the stress concentration near the hole region and the stitching reinforcement on the mechanical properties such as strength and modulus was studied. The laws of the stress concentration and distribution were investigated analytically and experimentally. The experimental results showed a distinct effect of stitching rein- forcement on composite laminates with holes, for which a reasonable design method was presented. |
