Mold for integral molding and manufacturing of carbon fiber grid bearing cylinder and molding method

Abstract

The invention provides a mold for integral molding and manufacturing of a carbon fiber grid bearing cylinder and a forming method. The molding mold comprises a metal molding mold body and a silicon rubber core mold body, wherein the metal molding mold boby comprises a first core mold, a second core mold, a third core mold, a fixed support, a split outer mold, cover plates and stripper plates, thesecond core mold is arranged inside the fixed support, the first core mold and the third core mold are arranged on the two sides of the fixed support, the cover plates are arranged on the two sides ofthe first core mold and the two sides of the third core mold, the stripper plates are arranged on the outer sides of the cover plates, the silicon rubber core mold is arranged on the fixed support and is located on the outer side of the second core mold, and the split outer mold is arranged on the periphery of the fixed support, the periphery of the first core mold and the periphery of the thirdcore mold. According to the mold, the problem that a reinforcing rib built-in bearing cylinder is complex in integral molding and large in stripping difficulty is solved. Compared with a post-gluing molding mode, a continuous fiber layer of the reinforcing ribs and a cylinder body is reserved to the greatest extent, so that the torsion performance is improved, and the risk caused by the quality defects of the gluing surface is avoided.

Description

technical field [0001] The invention relates to the technical field of composite material forming, in particular to a mold and a forming method for integrally forming a carbon fiber mesh bearing cylinder. Background technique [0002] The load-bearing tube structure has the advantages of strong anti-torsion performance, sufficient space utilization, wide bearing capacity, and low axial thermal expansion coefficient, making it the mainstream of the load-bearing structure of spacecraft such as satellites. In addition, with the rapid development and application of spacecraft manufacturing technologies such as satellites and spacecraft, higher requirements are put forward for the quality, mechanical properties, physical properties, and space performance of their materials. [0003] The application of lightweight materials has always been a hot spot in the aerospace field. Carbon fiber composite material is a lightweight material with superior comprehensive performance. Therefo...
