Abstract:

To optimize the multi-layer woven structure for improving the bulk density of fiber reinforcement , strength and modulus, a new multi-layer woven structure was researched —inter-layer warp connecting multi-layer fabric structure. The layers connected by superimposed warp running through various sub-layers, fabricating laminated fabrics with integral multi-layer structure. The paper described the principle of weaving, designed the special heddle and heald frame and weaving movement, and produced the multi-layer woven fabric with self-made weaving machine. Research shows that compared with traditional multi-layer structure, the fabric is closer and the degree of fiber bending lower because of the stacked structure in the result of a higher fiber volume density and tensile modulus, also the surface damage spreading along the thickness direction is lessened.
