Carbon fiber and basalt fiber weaving process

Abstract

The invention provides a carbon fiber and basalt fiber weaving process. The carbon fiber and basalt fiber weaving process comprises the following steps of: firstly, taking a nano-scale carbon fiber asan inner core, and then spinning and wrapping polyester yarns on the fiber to prepare basalt fiber yarns; then taking the carbon fiber as the inner core, and then wrapping nylon yarns and spandex yarns, which are used as outer wrapping yarns, on the carbon fiber through a high-speed wrapping machine according to two different spiral directions, namely a positive spiral direction and a negative spiral direction, so as to prepare flat carbon fiber yarns; taking the carbon fiber yarns as warp yarns and the basalt fiber yarns as weft yarns, wherein the warp yarns are of a three-layer structure and are combined in pairs; combining two longitudinal weft monofilaments by a first-layer warp yarn combination; combining two transverse weft monofilaments by a second-layer warp yarn combination; andcombining two longitudinal weft monofilaments by a third-layer warp yarn combination to obtain a three-warp flat yarn tissue. According to the weaving process provided by the invention, the nylon yarns and the spandex yarns are wrapped on the carbon fiber yarns in the positive direction and the negative direction, so that the tension is high and the carbon fiber and basalt fiber weaving process has a high-elasticity beam pressing effect. The three-warp flat yarn tissue is obtained, so that the wear resistance of a net body is enhanced and the service life is prolonged.

Description

technical field [0001] The invention belongs to the technical field of textile weaving, in particular to a carbon fiber and basalt fiber weaving process. Background technique [0002] As emerging composite materials, carbon fiber and basalt fiber have many advantages in terms of physical properties and adaptability, such as low density, high specific strength and specific modulus, stable structure size, high temperature resistance, fatigue resistance and wear resistance. and other excellent performance. [0003] At present, the weaving methods of warp-knitted multi-axially reinforced composite materials in the market are generally chain weave, warp-plain weave or variable warp-plain weave, and a combination of these methods. For composite materials, the braided warp is always woven along the warp direction, and the warp fibers only move in the warp direction without lateral movement. The binding thread is stitched and woven between fibers. Because the binding thread has a c...

[0003] At present, the weaving methods of warp-knitted multi-axially reinforced composite materials in the market are generally chain weave, warp-plain weave or variable warp-plain weave, and a combination of these methods. For composite materials, the braided warp is always woven along the warp direction, and the warp fibers only move in the warp direction without lateral movement. The binding thread is stitched and woven between fibers. Because the binding thread has a certain tension, the single warp The binding of the fibers together results in gaps between the warp fibers, and the gaps are filled with resin after they are made into products. Relatively speaking, the increase in the gaps will cause the resin matrix content to deviate and the volume content of the fibers will decrease. , leading to a decrease in the performance of the product, so a new weaving method needs to be proposed
