Abstract
Three-dimensional structures of multiaxial warp-knit (MWK) fabrics have been recently developed for multidirectional reinforcement of composites. Multilayers of linear yarns are assembled in warp (0 °), weft (90 °), and bias (±θ) directions to provide in-plane reinforcement in specific directions, and they are stitched together by knitting yarns to provide structural integrity and through-the-thickness reinforcement. Based on the experimental observations, the unit cell geometry of the MWK fabric is identified along with idealized cross-sectional shapes of insertion and stitch yarns. A geometric model is developed relating the geometric parameters and process variables. Expressing fiber volume fraction and fiber orientation in terms of structural and processing parameters, this geometric model provides a basis for the establishment of process windows for the MWK fabric preforms as well as for the prediction of the mechanical behavior of the MWK reinforced composites.
