Experimental Research on Bending Behavior of 2.5D Woven Fabrics

Six different kinds of fabrics were weaved using the 2.5D woven fabrics with warp-stuffer, The three point beam test method was employed to test bending behavior. The effect of yarn count, yarn fineness, fabric layers on the bending behavior of fabrics was analyzed. The results showed that warp and weft load, flexural stress, flexural strain and flexural modulus were increased as the yarn counts increasing; Warp and weft load, flexural stress and flexural strain increases as the fabric layers increased, flexural modulus decreased as the fabric layers increasing; load, flexural stress, flexural strain and flexural modulus increased as the yarn linear density increasing.
