Description
Technical Field
The invention relates to the field of three-dimensional weaving, in particular to a spindle blade special for ceramic fiber weaving, which is provided with a carrying yarn in a ceramic fiber weaving machine.
Background
The ceramic fibers include inorganic nonmetallic fibers such as silicon carbide (SiC) fibers, silicon nitride (Si 3N 4) fibers, quartz (SiO 2) fibers, basalt fibers, silicate fibers, and carbon fibers. The fiber has the advantages of high strength, high modulus, high temperature resistance, corrosion resistance, light weight and the like, is widely applied to the industrial key fields of marine ranches, aviation composite materials, aerospace ablation-resistant composite materials and the like, and has the irreplaceable advantages of other chemical fibers. The high-performance ceramic fiber composite material is prepared by compounding a reinforcement with a woven structure and resin or a ceramic matrix to obtain the high-performance composite material with high specific strength, high temperature resistance and corrosion resistance. Taking carbon fiber as an example, carbon fiber reinforced resin matrix composite is a key structural material in the field of aviation, the high performance of the carbon fiber reinforced resin matrix composite depends on a reinforcement skeleton woven by carbon fiber, and if the carbon fiber is damaged or part of tows are broken in the weaving process, the structural strength of the composite can be greatly reduced, and the reliability of a composite component is seriously influenced.
The spindle blade for storing the carbon fiber yarns is an essential main part of the ceramic fiber knitting machine, and in the using process, the spindle blade finishes yarn releasing and yarn drawing back according to constant tension; due to the characteristics of high modulus, brittle quality and no buckling of ceramic fibers, when the tension of yarns (ceramic fiber bundles) changes, stress concentration of a spindle blade of the conventional ceramic fiber braiding machine easily causes damage and even partial breakage of the fibers, and phenomena of fuzzing (partial fiber yarn breakage of fiber bundles) and inconsistent tension easily occur in the braiding process, so that the structural strength of a product can be greatly influenced, and the mechanical property of a composite material can be influenced. When yarn breakage occurs, the ceramic fiber knitting machine cannot stop working in time, so that fibers in the knitted prefabricated part are uneven, and the performance of the prefabricated part is greatly reduced. One yarn is formed by bundling a plurality of ceramic fibers; the ceramic fiber outside the yarn is easy to break due to external forces such as friction, bending and the like, so that the local bearing capacity of the yarn is reduced and the yarn is easy to break.
