Molding method of storage tank installation plate pre-buried frame

Abstract

The invention discloses a molding method of a storage tank installation plate pre-buried frame. The molding method comprises the following steps: laying a billet structure according to the dimension requirements of a relatively thin part of the pre-buried frame, and performing pressurizing and heating curing so as to obtain billets with needed dimensions; processing a structural member with a needed shape by a machine tool or manual work; installing a steel mould on a base, integrally and continuously laying up on a molded surface of the steel mould, embedding an independently molded structural member in the laying-up process, and independently laying in a peripheral soft mould; embedding a laid-up soft mould to a corresponding position, and completely laying a reserved area, and mounting peripheral surrounding strips for integrally closing the mould to the position; manufacturing a vacuum bag, performing pre-pumping treatment and placing the vacuum bag into a curing device for pre-pressing, and performing heating and pressurizing curing; and de-molding the soft mould and the surrounding strips, getting out the pre-buried frame, and clearing the mould and the surface of the pre-buried frame. According to the molding method disclosed by the invention, a method of combining independent molding, soft-mould laying and integral molding is adopted, so that the produced pre-buried frame has the stable quality and mechanical performances which meet the design needs, and is suitable for engineering application.

Description

technical field [0001] The invention relates to a molding method of a composite material structural part, in particular to a molding method of a pre-embedded frame of a tank mounting plate. Background technique [0002] The tank mounting plate is a common structural component in the satellite structure, and its main function is to provide an installation interface for the tank in the propulsion system. The embedded frame of the tank mounting plate is the most important part of the tank mounting plate. The embedded frame of the tank mounting plate must meet the static and dynamic environment required by the tank during satellite launch. The tank requires installation precision and the lightest possible weight. [0003] In the past, the inner frame of the tank mounting plate was mostly made of metal materials, and the structure was relatively simple, which could not meet the requirements of lightweight satellite structure, high specific stiffness, high specific strength and s...
