Abstract

A winding mandrel with a reversible half shaft and a fiber composite winding method relate to a winding mandrel and a winding method, in particular to a winding mandrel with a reversible half shaft and a fiber composite winding method. The present invention solves the problem that there is no opening at one end of the pole top of the hemispherical structure with a large diameter, which does not meet the biaxial winding requirements of the general winding machine, and brings great difficulties to the process forming. The invention includes a mold main body, a main shaft, a counterweight disc mounting part, a counterweight disc and a clamping and rotating connection shaft of a winding machine, and the mold main body, a main shaft, a counterweight disc mounting part, and a winding machine clamping and rotating connection shaft are sequentially connected from left to right , the weight plate is set on the weight plate mounting piece. The invention is useful in the field of materials science.

Description

technical field [0001] The invention relates to a winding mandrel and a winding method, in particular to a winding mandrel with a reversible half shaft and a fiber composite material winding method, belonging to the field of material science. Background technique [0002] The winding molding process is a process technology in which the continuous fiber soaked in the resin glue is wound on the mandrel according to certain rules, and then solidified and demoulded to obtain the product. For the load-bearing structure of spherical composite materials with a diameter greater than 1000mm, the laying and matching molding process is generally adopted, and at least two sets of outer molds should be made, which requires a lot of manual production of prepreg, cutting, laying and mold closing, which is time-consuming, laborious and costly. , The cycle is long. If the product is a sandwich structure, the outer skin cannot exert greater pressure to ensure the compactness of the skin, whic...
