Low-dielectric-constant glass fiber composite material and preparation method thereof
The invention relates to a low-dielectric-constant glass fiber composite material and a preparation method thereof. The composite material is prepared by filling epoxy resin with glass fiber. The glass fiber is composed of, in percent by weight, 51%-52% of SiO2, 20%-25% of B2O3, 10%-15% of Al2O3, 2%-6% of CaO, 2%-6% of MgO, 0.15%-0.3% of Na2O, 0-0.3% of K2O, 0-0.3% of Li2O, 0-0.9% of CaF2, 0-2% of TiO2, and 0-0.5% of ZrO2. The composite material possesses relatively good dielectric property, and possesses the dielectric constant of about 4.5 under 1 MHz. Also, the raw material cost is low, subsequent processing is easy, and the composite material is applicable as an enhanced material for a substrate of a printing circuit, and possesses relatively large commercial prospect.
