Cloth tape oblique winding equipment and method

Abstract

The invention discloses cloth tape oblique winding equipment and method. The device comprises a core mold, a pressing roller and a cloth tape; the core mold is used for winding the cloth tape, the surface of the pressing roller is in contact with the cloth tape wound on the core mold, and the pressing roller is used for pressing the cloth tape; the core mold is a reducing core mold; the pressing roller is of a multi-wheel-piece structure, a plurality of wheel pieces are arranged side by side to form the cylindrical pressing roller, and pricking pins are arranged on the surface of each wheel piece. According to the equipment, common plain carbon fiber cloth is used as a basic material of the cloth tape, and the cloth tape with the gradually-changed deformation rate does not need to be specially manufactured; and meanwhile, the cloth tape is heat-resistant adhesive tape adhered carbon fiber cloth, elongation of the heat-resistant adhesive tape is achieved, the toughness and the strength of the carbon fiber cloth are achieved, the cloth tape can be perfectly attached to the core mold, and a complete high-strength winding body is formed.

Description

technical field [0001] The invention belongs to the technical field of manufacturing composite material parts, and in particular relates to a tape oblique winding device and a winding method. Background technique [0002] Cloth tape winding is a commonly used production technology for modern solid rockets, mainly used for the converging section and expansion section of the nozzle of solid rockets and the heat shield of reentry spacecraft. Usually, pre-impregnated carbon fiber cloth tape is used to wrap the inner layer of the converging section and the expansion section of the solid hair nozzle to resist the erosion and ablation of thousands of degrees of high-temperature air flow; pre-impregnated high-silicone cloth is used between the outer shell and the inner wall Tape wraps as insulation. Re-entry spacecraft heat shields are usually wrapped with pre-impregnated high-silicone cloth tapes. [0003] Tape winding technologies mainly include parallel winding, overlapping win...

AI Technical Summary

Problems solved by technology

Although the special fabric with gradual deformation rate increases the deformation to a certain extent, at the same time, because the high temperature strength and ablation resistance are far inferior to carbon fibers, other fibers are used as warp yarns, which reduces the final ablation resistance of the winding body.

Even so, this technology is restricted by factors such as existing equipment, materials, and processes in actual use. It can only be wound at a fixed angle on a mandrel with a small diameter change, and it is difficult to implement variable angle and vertical winding.
