Glass fiber modified epoxy resin composite material and preparation method thereof

The invention discloses a glass fiber modified epoxy resin composite material, which is prepared from the following components in parts by mass: 60 to 80 parts of epoxy resin, 10 to 30 parts of filler, 5 to 15 parts of epoxy resin reactive diluent, 20 to 40 parts of curing agent and 20 to 30 parts of glass fiber. The composite material provided by the invention overcomes the heavy smell of styrene volatilized in the production process through the composite material using epoxy resin instead of unsaturated resin, the styrene is a toxic substance with an irritating smell, has volatility, and can pollute the environment, so the governance cost is high; mechanical properties and heat resistance of the epoxy resin is better than that of the unsaturated resin; the preparation process is simple, the processing is easy, and the processing cycle is short. 本发明公开了种玻璃纤维改性环氧树脂的复合材料，所述材料由如下按质量组份组成：环氧树脂60-80份，填料10-30份，环氧树脂活性稀释剂5-15份，固化剂20-40份，玻璃纤维20-30份。本发明提供了的复合材料，通过环氧树脂替代不饱和树脂的复合材料，克服了在生产的过程中挥发出来的苯乙烯气味大，且苯乙烯是种具有刺激性气味，有毒的物
