Abstract

Abstract:

The mixed woven composites being laid up by 2D woven and unidirectional carbon prepreg alternately have the advantages of high specitic stiffness, specific strength and impact performance, and the processibility is good also. In this paper, using dynamic finite element method based on 3D nonconforming layered element, alow-velocity impact finite element analysis of 2D mixed woven composite laminates is performed. The laminates are laid up by 2D woven and unidirectional carbon prepreg alternately.
