STRESS ANALYSIS OF 2.5D BRAIDED FIBER REINFORCED COMPOSITES

摘要：

A new model of representative volume elements of 2.5D braided fiber reinforced composites was proposed, which can represent the braided manner and coincides with the actual configuration. The finite element software ANSYS was adopted to analyze the stress distributions in this model. Through applying loads and finite element calculation, the stress field of this 2.5D braided composites in tension was obtained. The finite element calculation results fit well with the experimental data, which demonstrates the validity of this model. In addition, the influence of braiding parameters on the mechanical properties was investigated.
