Effect of Stıtch on Composıte Plate

Abstract

Experimental study is carried out on the stitching reinforcement of composite laminates. First, the tensile strength and stiffness are measured, and their dependence on stitching parameters such as stitching needle span, row spacing, edge distance and stitching type are analyzed. Next, the strain distribution and concentration are investigated analytically and experimentally for different stitching parameters, external load and edge location of the hole. It is shown that the results of stitching reinforcement are quite different for composite laminates with a circular hole, which could provide proper stitching parameters for designers. Resin and hardener are usually supplied two liquids in separate container. Here we conduct a various mechanical testing to define the material properties. Based on the property it can be used in spare parts on vehicle to increase the strength of the part. Later the material is experimented and values are noted.This material can be used in aerospace industries, automobile industries where the cost reduction can be achieved and quality can be increased.
