Abstract: The study on 3-D glass fiber sand-wich structures of warp knitting fabric based on the traditional warp knitting, including the study on the selection of raw materials of glass fiber ,fabric structure design, the weaving machine test and etc. The results show that optimize design of warp knitting fabric structure, select a smaller fineness, use lesser twist glass fiber yarn and in weaving process take proper lubrication processing for glass fiber, which can greatly reduce glass fiber for brittleness, electrostatic and easy to hook hair which cause of the yarn breakage. At the same time, choose woven knitting elements configuration, optimize the knitting shape, reasonable adjustment of the configuration parameters between stretch and warp, choose larger force angle, which can better improve the glass fiber woven performance, improve the quality shaping of 3-D sand-wich structures warp knitting, and make a value reference for the practical production.
