Abstract

  Due to the superior specific strength and stiffness, a fiber reinforced plastic (FRP) is applied to the various industrial fields such as aerospace, automobile and medical instruments. Especially, the FRP reinforced with textile architecture attracts an attention for its high performance and flexibility in material design. However, it is difficult to forecast the mechanical property of textile composites, because the stress distributions in textile structure under an applied loading is complicated. In this paper, the FE-modelling techniques for the numerical evaluation of 3D-woven composite is discussed. Firstly, a modelling method based on mesh super position FE analysis is proposed for several types of woven composites. Secondary, the effects of textile size and wave pattern of stress fields are investigated. As a result, stress concentration points, which are considered as failure initiation site of textile structure, can be controlled by changing weave patterns.
