  • A method was presented for estimating 3D effective elastic modulus of multidirectional filament-wound hybrid tube. The effective elastic modulus of glass-carbon fibre wound tube was calculated. In order to consider the influence of hybrid effects, the hybrid effect coefficient was introduced. The volume friction of carbon fibre, layered structure, fibre dispersion, etc were considerd for the glass-carbon winding structure. The test results show that effective elastic modulus based on the present method is accurate. The method can greatly reduce the size of problem for stress analysis, because complex structure can be equivalent to homogeneous anisotropic material.
