Abstract

The invention discloses a high-temperature-resistant foam A-interlayer composite antenna cover and a preparation method thereof, and relates to the technical field of resin-based composite structure forming processes. The high-temperature-resistant foam A-interlayer composite antenna cover is constituted by an outer skin, a foam core layer, an inner skin and a reinforcing layer, and the outer skin, the inner skin and the reinforcing layer are made of fiber-reinforced resin-based composites, and the foam core layer is made of high-temperature-resistant resin foam; after being prepared and formed, the outer skin and the inner skin serve as moulds, the foam core layer is overall formed, the preparation precision of the interlayer antenna cover is ensured, and the influences of gaps between the skins and the core layer on the strength and performance of the antenna cover are avoided; and for meeting the high-bearing requirement for the root of the antenna cover, a thickening layer is laidon the root, the structural strength of the root of the antenna cover is improved, and meanwhile, connecting and assembling of the antenna cover are facilitated. According to the high-temperature-resistant foam A-interlayer composite antenna cover, the high-precision preparation problem of the high-temperature-resistant foam A-interlayer composite antenna cover is solved, the working demands of the interlayer antenna cover for high-temperature resistance and high strength are met, and realizing is convenient.

Description

technical field [0001] The invention relates to the technical field of resin-based composite material structure molding technology, in particular to a high-temperature-resistant A sandwich composite radome and a preparation method thereof. Background technique [0002] In order to improve the precision strike, anti-jamming and multi-target capabilities of guided weapons, countries around the world are competing to adopt ultra-wideband guidance technology to expand the working frequency band of the guidance system to ultra-wideband. As a key link in the guidance system, the development of ultra-wideband radome has become a bottleneck problem that needs to be solved urgently. Traditional radome mostly adopts a solid half-wave wall structure, which has the advantages of high strength and good wave transmission performance at specific frequency points, but it is difficult to achieve broadband wave transmission because of its narrow wave transmission frequency band and heavy weig...
