Problems solved by technology

[0003] As a structural engineering material with unique properties in the family of inorganic non-metallic materials, glass fiber has a series of excellent properties such as high strength, high modulus, corrosion resistance, and high temperature resistance, and is widely used in aviation, aerospace, transportation, electronics, etc. Various fields of the national economy, but the electrical insulation of the glass fiber itself limits the expansion of its application field. Chen et al. reported in Carbon47 (2009) 922-925 that an epoxy resin-based graphene composite material was prepared by an in-situ method , which has good electromagnetic shielding ability, and the electromagnetic interference frequency range reaches 8.2-12.4GHz
