Problems solved by technology

[0002] The oxygen index of epoxy resin is generally around 18-20, that is, it is flammable in the air, and it will burn under the continuous action of external heat source. At the same time, epoxy resin has insufficient toughness and poor impact resistance after curing. The defects of easy cracking and poor heat resistance, the mechanical properties, heat resistance and flame retardancy of FRP obtained with epoxy resin as a matrix are not very good, which limits its application

Description

technical field [0001] The invention relates to the technical field of glass fiber reinforced plastics, in particular to epoxy resin glass fiber reinforced plastics for the shell of a four-wheel electric vehicle. Background technique [0002] The oxygen index of epoxy resin is generally around 18-20, that is, it is flammable in the air, and it will burn under the continuous action of external heat source. At the same time, epoxy resin has insufficient toughness and poor impact resistance after curing. The defects of easy cracking and poor heat resistance, the mechanical properties, heat resistance and flame retardancy of FRP obtained with epoxy resin as a matrix are not very good, which limits its application. Contents of the invention [0003] Based on the technical problems existing in the background technology, the present invention proposes a kind of epoxy resin glass fiber reinforced plastics for the shell of four-wheel electric vehicles, which has high mechanical str...
