Abstract

The invention discloses a forming method for an antenna housing based on single layer sandwich foam prefabricated body resin. The forming method comprises the following steps of cutting a foam flat plate to obtain a plurality of flat plate foam units; respectively performing compression molding and peripheral processing on the flat plate foam units to obtain polygon-shaped foam prefabricated bodyunits; paving a first vacuum auxiliary layer, a plurality of layers of fiber cloth, an antenna housing sandwich foam prefabricated body formed by splicing foam prefabricated body units, a plurality oflayers of second fiber cloth and a second vacuum auxiliary layer in a forming mould in sequence; and introducing a resin-based permeable colloidal material between the first vacuum auxiliary layer and the second vacuum auxiliary layer and curing to form an antenna housing blank. The preparation of a foam prefabricated body ensures the configuration of antenna housing sandwich foam with complex curvature molded surfaces; various layers of housing body are cured layer by layer in a curing process, so that the interlayer defects of the housing body are reduced; the state of various layers of thehousing body can also be detected layer by layer; the overall quality of the antenna housing is ensured; the overall strength and rigidity of the antenna housing are improved; and the bearing capacity of the antenna housing is improved.

Description

technical field [0001] The invention relates to the technical field of radome, in particular to a method for forming a resin-based radome of a single-layer sandwich foam prefabricated body. Background technique [0002] The radome, also known as the radome, is a shell structure that protects the antenna from the natural environment. As an important part of the radar system, its importance lies in providing an all-weather working environment for the radar antenna. Now it is widely used in large ground Radome, Airborne Radome, Shipborne Radome, Missile Radome, etc. As the electromagnetic window to protect the antenna, the radome must not only meet the wave-transmission requirements of the antenna, but also maintain a stable and complete state under the action of the load, without harmful deformation and damage, and the structural strength meets safety. [0003] According to the cross-section of the cover wall, the radome can be divided into uniform single layer, A interlayer,...
