摘　　要：A new geometric model of Multiaxial Warp-Knitted (MWK) performs, which is based on the experimental observations and analysis of basic stitch, is developed to relate the geometric parameters and process variables. The fiber volume fraction and fibre orientation of MWK reinforced composites are described in terms of structural and processing parameters in the model. And this model provides a basis for the prediction of mechanical behavior of the MWK reinforced composites.A new geometric model of Multiaxial Warp-Knitted (MWK ) performs, which is based on the experimental observations and analysis of basic stitch, is developed to relate the geometric parameters and process variables.
