  • EPOXY-BASED RESIN COMPOSITION FOR CLEAR FIBER COMPOSITES AND EPOXY-BASED CLEAR FIBER COMPOSITES
    Publication number: 20240392086
    Abstract: An epoxy-based resin composition for clear fiber composites includes epoxy resins and an anhydride curing agent. The epoxy resins include at least one epoxy resin having a refractive index higher than a refractive index of glass fibers, and at least one cycloaliphatic epoxy resin. The amount of non-aromatic components in the epoxy-based resin composition is 60 wt % or higher, based on the total amount of the epoxy resins and the anhydride curing agent. An epoxy-based clear fiber composite for a cover plate in a solar cell panel includes a cured matrix resin and a fiber reinforcement. The epoxy-based clear fiber composite has a refractive index ranging from 1.520 to 1.530 or 1.550 to 1.565, while the difference between the refractive index of the fiber reinforcement and the cured matrix resin is 0.001 or less. A multi-layer epoxy-based clear fiber composite includes a plurality of the epoxy-based clear fiber composite.
