The composite laminate design and manufacture based on wrapped ply

Abstract

This paper analyzes the layup design and manufacture of composite laminate with inserts on the surface of revolution, and points out that both the interior surfaces and the outer surfaces should be laid as a full-body ply. Utilize 3D design software Catia and composite design software Fibersim, carry out digital layup and producibility simulation of the product, design wrapped plies for the interior surface and outer surface with complex structures, simulate and adjust the laying process, and make the fiber deformation of the entire surface reasonable. Flat patterns of the plies are provided for material cutting. For the layup of thicker area and transition area of the product, the layup design and production data and suggestions are also given. The scheme and data of layup are well used in guiding production and improving production efficiency and product quality.
