Quartz fiber/polyimide composite material radome and preparation method thereof

The invention relates to a quartz fiber/polyimide composite material antenna housing and a preparation method thereof. The preparation method comprises the following steps: preparing a mold pressing mold; preparing a quartz/polyimide prepreg; cutting the quartz/polyimide prepreg, loading the cut quartz/polyimide prepreg into a mold pressing mold, and carrying out mold pressing forming and demolding by adopting a mold pressing net size forming process to obtain a prefabricated antenna housing; the method comprises the following steps: coating moisture-proof paint on an arc-shaped cover plate, a rectangular-ambulatory-plane frame and a heat insulation cushion block of a prefabricated radome, and after coating, coating a conductive coating on the rectangular-ambulatory-plane frame to obtain a quartz/polyimide composite radome; the technical problems that according to an existing composite material antenna, a heat insulation pad is bonded with an antenna housing body through a post-bonding method, the process is
