Modified glass fiber reinforced epoxy resin composite material and preparation method thereof

The invention discloses a modified glass fiber reinforced epoxy resin composite material and a preparation method thereof. The method comprises the following steps: firstly, drying organic montmorillonite and diluting epoxy resin; secondly, adding organic montmorillonite into the diluted epoxy resin, stirring and dispersing, and carrying out ultrasonic oscillation on the stirred mixed solution; carrying out vacuum degassing on the mixed solution subjected to ultrasonic oscillation, and adding a curing agent into the degassed mixed solution; glass fiber cloth is laid again, then resin is coated with the compression roller, and bubbles are removed; then, the materials are subjected to high-temperature curing and demolding; and finally, placing the cured composite material in a gamma irradiation device for irradiation. Compared with common GFRP, the modified glass fiber reinforced epoxy resin composite material has high mechanical strength, high thermal stability, thermal insulativity and electrical insulativity
