Problems solved by technology

[0005] External coating method, which sprays conductive paint or conductive paint on the surface of FRP products, but the conductive FRP prepared by external coating method is easily damaged due to the exposed conductive layer
[0006] The internal doping method, in which conductive materials are mixed in the preparation process of FRP; among them, some conductive materials mixed are conductive powder materials, such as carbon black, graphite, silver powder, etc.; some conductive materials mixed are conductive fibers, such as Metal fibers, carbon fibers, metal-plated fibers, etc.; however, in order to achieve the required conductivity, the conductive FRP prepared by the internal mixing method requires a large amount of conductive materials mixed into it, which can easily reduce the overall performance of FRP.

Abstract

The invention mainly aims to provide a conductive glass fiber reinforced plastic, a conductive glass fiber reinforced plastic plate and a preparation method of the conductive glass fiber reinforced plastic plate. The conductive glass fiber reinforced plastic comprises a base material and metal-plated glass fibers, and the metal-plated glass fibers comprise nickel-copper alloy-plated hollow glass beads with the particle size of 40-70 [mu]m, uncoated glass fibers and carbon fibers. The technical problem to be solved is to introduce the nickel-copper alloy-plated hollow glass beads into the glassfiber reinforced plastic and combine the metal-plated glass fibers and the carbon fibers to form a continuous conductive network, so that the glass fiber reinforced plastic has a good conductivity ata small addition amount and also has an excellent mechanical strength, thereby the glass fiber reinforced plastic is practical.
