Abstract

Knitted fabrics are made by the interlocking of loops of yarn. Weft knitted fabrics are produced by the same yarn which forms loops successively at each needle of the needle bed during the same knitting cycle. This paper describes the prediction of tensile properties of thermoplastic composites reinforced with weft knitted fabrics. The tensile properties of weft knitted fabric composites in wale direction decreased linearly with increasing stitch density. The range of the orientation angle of cross-over part were 2.5$^{\circ}$$\leq$$\theta$$\leq$8$^{\circ}$. The tensile strength of plain knitted fabric composites in wale direction were about 2.0 times higher than that of rib knitted fabric composites of the same apparant density.
