Manufacturing method of solid wall composite material radar cover

Abstract

The invention relates to a manufacturing method of a solid wall composite material radar cover. The manufacturing method comprises the following steps: 1) a female mold and a male mold are manufactured; and glass cloth prepreg is paved on the female mold; 2) the female mold is sealed; 3) the temperature-keeping and pressure-keeping curing is performed; and finally, the cooling and the pressure reduction are performed to open the mold; 4) the remainder is cut; the inner surface of a semi-finished product is wiped by acetone; and the semi-finished product is put in the female mold; 5) the inner surface of the radar cover semi-finished product is coated with a layer of adhesive for manufacturing the glass cloth prepreg, and is paved with two layers of glass cloth prepreg; 6) the female and male molds are closed; 7) the closed female and male molds are sealed; and 8) the temperature and the pressure are increased for curing formation; and the pressure is reduced to open the mold. The female and male molds are closed; a hot pressing tank is heated, pressed and cured; the thickness of the radar cover is precisely controlled through the female and male mold closing mode; the internal structure uniformity of the radar cover is guaranteed through the hot pressing tank curing process; the electric performance requirement of the radar cover is guaranteed; the final state requirement of the radar cover is once achieved; the production period is shortened; and the cost is reduced.

Description

technical field [0001] The invention relates to the field of radome manufacturing, in particular to a method for manufacturing a solid-wall composite material radome. Background technique [0002] There are currently two methods commonly used for the manufacture of solid wall radome: the first method is positive mold forming with electrical thickness measurement and shape grinding; the second method is RTM forming process with electrical thickness spraying correction equipment. Method 1. The radome that has passed the electrical thickness measurement after grinding still needs to be painted with a protective coating on its outer surface. The protective coating has a great influence on the final electrical performance of the radome, and the radome cannot be used after the surface coating is sprayed. Grinding the thickness of the radome; Method 2 has a uniform degree difference in the internal structure of the radome, and spraying introduces a new medium, and the appearance of...

Method 1. The radome that has passed the electrical thickness measurement after grinding still needs to be painted with a protective coating on its outer surface. The protective coating has a great influence on the final electrical performance of the radome, and the radome cannot be used after the surface coating is sprayed. Grinding the thickness of the radome; Method 2 has a uniform degree difference in the internal structure of the radome, and the spraying introduces a new medium, and the appearance of the new medium affects the electrical performance of the radome

Both of these two manufacturing methods are due to the electrical thickness measurement and reprocessing of the radome during the manufacturing process, resulting in long production cycles and high manufacturing costs.
