Abstract
The invention discloses a high-dielectric low-loss phenolic glass fiber composite material and a preparation method thereof. The composite is composed of the following components in percentage by weight: 64.2 to 65.0% of EW-200 glass fiber plain cloth, 29.8 to 30.2% of phenolic resin, 4.6 to 5.8% of barium titanate, and 0.2% of coupling agent. The provided composite material has the advantages of lightness, high strength, and high temperature resistance of a phenolic glass fiber composite material. Furthermore, barium titanate powder is added to increase the dielectric constant of the composite material, and thus the thickness of an antenna cover made of the composite material is reduced.
