hybrid composites three dimensional orthogonal woven repeated unit cells mechanical properties glass-carbon fibre
To further develop hybrid fibre three-dimensional woven composites in the field of aerospace,the mechanical properties at X direction of three-dimensional orthogonal woven glass-carbon hybrid composite are researched by numerical simulation and experimental methods.Micro structures of composites are determined based on the assumption theory by understanding the structure parameters of fabrics.The symmetrically repeated unit cell is selected and the finite element method model is established to predict the mechanical properties at X direction of hybrid composites by using the methods of gradual damage.Specimens of three-dimensional orthogonal woven glass-carbon hybrid composites are manufactured with Resin tranfer molding equipment.Tensile and compressive tests for mechanical properties at X direction of composites are performed.The accuracy of numerical simulation method is verified by discussing the error between experimental data and theoretical data.The advantages and disadvantages of three-dimensional orthogonal woven glass-carbon hybrid composites are discussed by comparing with three-dimensional orthogonal woven glass composites.The research results provide important references for application of the hybrid composite.
