In one embodiment, the resin composition may include an epoxy resin and a curing agent, and both the epoxy resin and the curing agent are transparent materials.

In one embodiment, the resin composition is a composition composed of an epoxy resin and a curing agent, for example, the epoxy resin is E44 epoxy resin, and the curing agent can be T31 curing agent, but the present invention is not limited to epoxy resin and curing agent. The specific type of curing agent. Wherein, in the resin composition, the epoxy resin accounts for 30% to 85% by weight, and the curing agent accounts for 20% to 50% by weight.

Next, a carbon fiber fabric layer is formed on the resin composition layer. Here, carbon fiber filaments can be woven to form a sparse carbon fiber fabric in advance, and the carbon fiber fabric layer can be formed on the resin composition layer by laying the sparsely woven carbon fiber fabric on the resin composition layer.

Finally, the above-mentioned mold is heated, specifically, the mold is heated based on a predetermined temperature, and the heating is continued for a predetermined period of time, so that in the mold heated to the predetermined temperature, a sheet-like shape can be formed based on the resin composition layer and the carbon fiber fabric layer.
