EFFECT OF SHORT GLASS FIBER ON LAYER TEARING PROPERTIES OF MULTI AXIAL WARP KNITTED LAYER COMPOSITES

Abstract

Abstract: By using the glass fiber multi axial warp knitted fabric as reinforcement, epoxy resin as matrix and adding, short glass fiber to glass fiber fabric reinforced layer, multi-axial warp knitted fabric for composites containing short glass fiber between glass fiber layer was prepared. The short glass fibers between glass fiber fabrics were observed by using SEM after tests, the tensile and tear strength of the composite was tested and studied by the universal mechanical testing machine. The results show that under the same conditions, the layer tearing property of composites treated was obviously enhanced. The load displacement curve of initial slope is large, and the composites are not easy to be destroyed by tearing load form.

Key words: glass fiber, multi axial warp knitted fabric, composite, layer tearing property, interface property
