Design of warp knitted multi-axial grid fabrics for reinforcing cement

The purpose of this study is to provide theoretical basis for the research of textile reiforcing cement-based composite.Thus the configuration characteristics of warp-knitted multi-axial grid fabrics for reinforcing cement based composite material are analyzed.With reinforcing cement based composite materials as a starting point,based on the size of grid and mechanical properties,the selection of reinforcing yarn,the direction and layout mode of yarns and the binding construction are elucidated.The computational methods for calculating the gauge of yarns and areal density of fabric are obtained.Finally,a quadric-axial warp knitted grid fabric is produced and its mechanical properties are tested to demonstrate that it is possible to design corresponding multi-axial grid fabrics to meet the requirements of practical needs for reinforing cement based composite material.
