Bending Properties of Three-Layer Biaxial Weft Knitted Fabric Reinforced Composite Materials
In this paper, three-layer biaxial weft knitted fabric(TBWK) made of carbon fiber as inserted yarns and polyester yarns as knitted yarns , which is a kind of non-crimp fabric, has been impregnated with epoxy via RTM technique. The bending properties of the TBWK fabric reinforced composite materials with different fiber volume fraction have been investigated. The bending strength of TBWK reinforced composites with fiber volume fraction of 48.8% can reach 821.1 MPa. The results show that this kind of composites has good bending properties, and load - deflection curve shows obvious linear features.
