Effect of process parameters on the mechanical properties of co-wrapped PP/flaz yarn

摘要：

The effect of weaving and process parameters on the mechanical properties of thermoplastic preforms and composites produced from co-wrapped PP/flax yarn were investigated. The results show that the co-wrapped yarns can be used to form textile preforms for manufacturing textile structural composites. The changes in weaving density have greater impact on the tensile properties of composite sheets, an integrated facilitative weaving and the tensile properties in warp and weft of composites to a collaborative role can be set at a smaller warp density range and a moderate level of weft density. By orthogonal design and analysis of variance method, optimize the hot forming process parameters on properties of composites, with 6 MPa, 5 min and 185℃. The hotpressing thermoplastic composites with co-wrapped yarns preforms from natural flax fibers and thermoplastic resin PP, have better combination of interface and mechanical properties, and co-wrapped yam as a form of preforms provide an e-conomic and effective way to preparation for the continuous fiber reinforced thermoplastic resin composites.
