Fiber winding machine and winding method

Abstract

The invention discloses a fiber winding machine and a winding method. The fiber winding machine comprises a moving device, a core mold, a warp winding head, weft winding heads and warp supply devices; the warp winding head is arranged on the outer side of the moving device in a surrounding mode, the core mold is arranged on the moving device, and the core mold and the warp winding head are coaxially arranged; the weft winding heads are arranged at the positions, on the two sides of the warp winding head, of the moving device; and the warp supply devices are arranged on the two sides of the moving device and connected with the warp winding head. The helical angles of warps on the same layer flat laid on a cylindrical surface relative to the axis of the core mold are the same, and mutual overlapping does not exist; the adjacent warp layers in the radial direction of the cylindrical surface do not overlap with each other, so that cross bending of fibers is reduced, the mechanical property of the high-strength fibers can be better exerted, and winding bodies are firmer and lighter; and compared with a traditional fiber winding machine, the production efficiency of the winding machine can be greatly improved.

Description

technical field [0001] The invention belongs to the technical field of manufacturing high-pressure containers of composite materials, and in particular relates to a fiber winding machine and a winding method. Background technique [0002] Combustion chamber shells of composite solid rocket motors are manufactured by high-strength fiber winding process. The body is both light and strong. However, the production efficiency of the traditional filament winding process is low. A bundle of yarns is reciprocated and wound many times to cover a longitudinal winding layer. During the winding process, the reciprocating longitudinal yarns will inevitably collide with the previously wound yarns during spiral winding. Overlapping occurs and causes a large number of micro-bends to the fiber bundles, which reduces the effective use of the strength of the fiber material; especially frequent overlapping at the two ends of the head will form a lot of gaps under the yarn, which has relatively...

Problems solved by technology

However, the production efficiency of the traditional filament winding process is low. A bundle of yarns is reciprocated and wound many times to cover a longitudinal winding layer. During the winding process, the reciprocating longitudinal yarns will inevitably collide with the previously wound yarns during spiral winding. Overlapping occurs and causes a large number of microbends to the fiber bundles, which reduces the effective use of the strength of the fiber material; especially frequent overlapping at the ends of the ends will form a lot of gaps under the yarn, which has relatively low shear and compression resistance. Poor high-strength fibers pose a danger, forcing the addition of other materials for reinforcement at the head, thereby increasing the weight of the shell
