Spinning three-dimensional weaving equipment for continuous ceramic filaments

Abstract

The invention relates to spinning three-dimensional weaving equipment for continuous ceramic filaments. The spinning three-dimensional weaving equipment comprises a filament releasing mechanism, an oiling device, a drying device, a constant tension device and a weaving device which are sequentially arranged in the machining direction. The continuous ceramic filament is led out through the filament releasing mechanism, is subjected to tension adjustment in the filament releasing mechanism and then is input into the oiling device; the oiled continuous ceramic filaments enter a drying device to be heated in a heat radiation mode, so that redundant oiling agent is removed; the tension of the dried continuous ceramic filaments is adjusted again through a constant tension device, and then the continuous ceramic filaments are knitted through a four-step method through a warp knitting device. Compared with the prior art, the method has the advantages that the problems that the oxide ceramic filaments are high in brittleness and easy to break under stress in spinning and three-dimensional weaving processes are solved, the doubled continuous filaments are bundled into large tows, yarns with excellent performance are provided for three-dimensional weaving, and continuous and stable production of three-dimensional woven fabrics of continuous ceramic fibers is realized.

Description

technical field [0001] The invention relates to the field of weaving equipment, in particular to a three-dimensional weaving equipment for spinning continuous ceramic filaments. Background technique [0002] With the rapid development of aerospace vehicles, missiles and aircraft, higher requirements have been placed on ultra-high temperature materials. Not only are they required to have high strength and modulus, but also low density, high temperature resistance, corrosion resistance, and excellent dielectric properties. Continuous ceramic filaments reinforced ceramic, metal and resin matrix composites in two-dimensional and three-dimensional braided shapes have become a research hotspot for ultra-high temperature materials. [0003] The three-dimensional braided composite material is a product formed by the combination of three-dimensional braided prepolymer and matrix material. It not only solves the problems of easy delamination, low strength in the thickness direction, ...
