Abstract

Abstract:

The mechanical properties of braided structural composite materials are analyzed. The modified classical laminated theory forms the basis of the present approach. Considering the effect of thickness, three dimensional stress strain analysis is adopted. The effective elastic modulus is predicted. In addition, the mechanical experiments of braided structural composite materials are carried out. The theoretical prediction shows reasonably good agreement with the test result.

Key words: composite materials, three dimensional braiding, mechanical properties
