Abstract

The invention discloses a piezo-infiltration molding method for latent composite material radome. The technical problem to be solved is to provide a low-cost overall preparation method for composite material radome, so that the prepared composite material radome has strict dimensions and wall thickness. Uniform, smooth inner and outer surfaces, excellent dielectric properties, and high overall load-bearing performance. The technical solution is to prepare the mold and materials first, then prepare the fiber-reinforced preform, close the mold and seal it, then connect the valve and pipeline, carry out resin mixing, glue storage tank, and then carry out resin pressure infiltration, including normal pressure impregnation. Infiltration and pressure infiltration, and finally curing and demoulding and post-treatment. The preparation of the composite material radome by the present invention is easy to operate and low in cost; it can flexibly adjust the pressurization speed of the resin glue liquid to the mold cavity, and the adjustment range is large, which is especially beneficial to the slow impregnation and integral molding of the composite material radome with a thick-walled structure. .

Description

The pressure infiltration forming method of latent composite material radome Technical field The present invention relates to a kind of preparation method of composite material member, especially a kind of for protecting submarine communication system Integral molding method of composite material radome. Background technique Submarine plays a pivotal role in the modern offensive and defensive system as the important combat power of modern navy. latent The advanced radar countermeasure and reconnaissance equipment equipped on submarines plays an increasingly important role in ensuring the safety of submarine platforms, concealed attacks and intelligence reconnaissance. important role. [0003] The radar antenna-radome system is one of the important hardware facilities of the submarine communication system. The radome is used to withstand deep Seawater pressure, isolated from the seawater environment, ensures that the antenna inside the cover can work normally under ha...
