The application provides a high and low temperature resistant, acid and alkali resistant, and radiation resistant wave-transparent polyphenylene sulfide composite material, which is made of the following raw materials in parts by weight: polyphenylene sulfide resin 40-65 parts, high-density polystyrene resin 10-25 parts, low-dielectric glass fiber 15-35 parts, compatibility agent 3-8 parts, low-dielectric filler 10-25 parts, lubricant 1-3 parts, compatibilizer 3-6 parts, and antioxidant 1-2 parts. The application also discloses a preparation method of the wave-transparent polyphenylene sulfide composite material. The wave-transparent polyphenylene sulfide composite material provided by the application can meet the strict requirements of performance of wave-transparent materials in special environment fields such as aerospace, intelligent driving of automobiles, 5G / 6G communication and chemical industry.

The application provides a wave-transparent composite material panel, a radar cover and a manufacturing method. The wave-transparent composite material panel comprises a structure layer, a wave-transparent layer and a protective layer wrapped outside the structure layer and the wave-transparent layer, wherein the structure layer comprises at least two foam layers, the wave-transparent layer comprises at least two hollow fabric composite material layers, the two adjacent foam layers and the two adjacent hollow fabric composite material layers are spaced apart by the protective layer, the reinforcing body of the hollow fabric composite material layer is woven by glass fiber yarn, and the protective layer is formed by laying glass fiber cloth first and then pouring resin. The wave-transparent composite material panel can ensure the mechanical property and the wave-transparent property simultaneously.
