叠经层连多层机织物增强体的结构设计及试织

为优化多层机织物结构，提高增强体的纤维体积密度、强度及模量，设计出叠经层连式多层结构机织物。这种结构由专门起连接作用的经向纱线，将组织结构完整的各子层结构以经纱叠合层与层之间连接的方式组构成整体多层织物结构。提出其织制原理，并对作为主要织机机件的综丝和综框进行构型、组合及织制运动设计，自制实验织机并进行试织。结果表明，与传统的多层结构织物相比，因叠经层连的方式固紧了组织结构，降低了纤维弯折程度，故具有较高的纤维体积密度和拉伸模量，且织物表层的损伤不易沿织物厚度方向扩散。

Design and trial-weaving of multi-layer reinforcement fabric with superimposed warps

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.
