Investigation on Tensile Properties of Two Guide Bar Warp Knitted Fabric Reinforced Composites

Abstract:

The composite laminates are produced by manual molding technology using two guide bar warp knitted fabrics of glass fiber as reinforcement and epoxy resin as matrix. The tensile properties of composites in the course, wale and diagonal directions are tested on the universal material testing machine. The influences of warp knitting stitch structures for mechanical performance of the composites are discussed. The results show that the tensile stress/strain curves of two guide bar warp knitted fabric reinforced composites were nonlinear. The tensile properties of composites possess obvious anisotropic characteristics. The tensile strengths and modulus of the warp knitting fabric composites depend on the yarn numbers bearing load along tensile direction, which are related to the stitches and structural parameters of warp knitted fabrics.
