Prediction of mechanical properties on 3D braided composites with void defects

Void defects have appeared inevitably during the manufacturing process of braided composites, which directly affect the mechanical properties and strength of braided composites. First, the influence of internal void and porosity on the mechanical properties of resin was predicted. Second, the evolution in the mechanical properties of three dimensional (3D) braided composites was obtained using the Mori-Tanaka method. Finally, the strength...
