Abstract

A procedure of predicting mechanical properties of braided composites was developed. Mechanical behaviors of yams and resin in the composites were represented by elastoplastic constitutive relations. The mechanical properties of the hybrid braided composites were calculated using Method of cells and finite element method. Predictions of finite element method showed good agreement with experimental data but Method of cells predicted lower values than those of the experiment.
