| description | The invention discloses a low-dielectric glass fiber reinforced PC/PPO composite material and a preparation method thereof. The raw material formula of the PC/PPO composite material consists of the following components in percentage by mass: 29.8 to 41.5 percent of polycarbonate, 29.7 to 38.0 percent of modified polyphenyl ether, 20.0 to 40.0 percent of short cut low dielectric glass fiber, 0.1 to 0.4 percent of antioxidant and 0.3 to 0.6 percent of dispersing agent. The Dk of the composite material is reduced to 2.83-3.10, the Df is reduced to 1.53 * 10 to 2.40 * 10, the application requirements of 5G/6G on low dielectric materials can be met, and the good compatibility and the low melt viscosity ensure that the composite material has high mechanical properties and excellent molding processing properties.
