Problems solved by technology

In the three-dimensional weaving process, the tension yarn on the yarn carrier connects and drives the ceramic fiber bundles to weave. Due to the shortcomings of ceramic fibers such as low elongation, high brittleness, and resistance to bending, it is easy to fluff and damage during the weaving process, especially At the connection with the tension thread, the tension yarn is easy to slip off, and the fiber is broken, which increases the difficulty of weaving and reduces the weaving efficiency
The invention provides a simple and easy method for joining ceramic fiber bundles, which solves the problems of poor connection fastness and easy breakage of ceramic fiber bundles at present, can improve the manufacturing efficiency of three-dimensional weaving, and ensure the product performance of three-dimensional weaving preforms

Abstract

The invention discloses a ceramic fiber bundle knotting method. According to the knotting method, ceramic fiber bundles and a tension wire are entangled and bound by a connecting yarn, and a firm connecting effect is achieved. The method has the advantages that by increasing the cohesion force among fibers, slippage can be effectively avoided, the weaving efficiency and the product quality are ensured, and the method is suitable for industrial actual production.

Description

technical field [0001] The invention relates to a method for binding ceramic fiber bundles, which is especially suitable for bonding ceramic fiber bundles, connecting yarns and tension yarns. Background technique [0002] Ceramic fiber is an important variety of high-performance reinforcing fiber for advanced composite materials. It has the advantages of light weight, high temperature resistance, good thermal stability, low thermal conductivity, small specific heat and mechanical vibration resistance. It is used in metallurgy, chemical industry, transportation, aerospace, The scope of application of cutting-edge science and technology fields such as military protection is gradually expanding, and the development prospects are very broad. In the three-dimensional weaving process, the tension yarn on the yarn carrier connects and drives the ceramic fiber bundles to weave. Due to the shortcomings of ceramic fibers such as low elongation, high brittleness, and resistance to bend...
