Experimental and Numerical Simulation?of the Tensile Behaviour of a Biaxial?Warp-knitted Composite

摘要

In this paper a composite reinforced with biaxial warp-knitted fabric and epoxy resin was?manufactured by applying vacuum assisted resin transfer moldings (VARTM). The quasi-static tensile behaviour was experimentally tested in 0° and 90° directions, respectively.?A finite element model of biaxial warp-knitted composites was developed on a meso-scale.?The tensile behaviour of the composites was numerical simulated and compared with the?experimental results. It showed that there is an approximate agreement between experimental?and numerical results. There are maximum errors sum of squares of 14.52% and 33.29%.?The finite element model of biaxial warp-knitted composites has higher accuracy, which?can be used to study the static and dynamic mechanical properties.
