Problems solved by technology

However, in ordinary polyester FRP, the bonding force between glass fiber and resin matrix is ​​weak, the physical properties such as bending strength are low, and the softening point is lower than 90°C, which is difficult to meet the requirements of some special occasions, such as aerospace, Automobiles, construction, fitness equipment, etc. need to be further enhanced; at the same time, in order to obtain the required conductivity, carbon powder or other metal micropowders are added to the resin, and the amount of conductive powder added is large, which is easy to produce FRP. performance degradation

Description

technical field [0001] The invention relates to the technical field of composite materials, in particular to a conductive glass fiber reinforced plastic product and a preparation method thereof. Background technique [0002] Glass fiber (original name in English: glass fiber or fiberglass) is an inorganic non-metallic material with excellent performance. Brittle, poor wear resistance. It is generally made of glass balls or waste glass through high-temperature melting, wire drawing, winding, weaving and other processes. The diameter of its single filament is several microns to more than 20 microns, which is equivalent to a hair 1 / 20~1 / 5 of silk, and each bundle of fiber precursors is composed of hundreds or even thousands of single filaments. [0003] Graphene, as an allotrope of carbon, is a single-layer two-dimensional crystal material with a honeycomb structure formed by the hybridization of carbon atoms according to sp2 orbitals. Graphene has good mechanical properties ...
