A fatal weakness in the use of epoxy resin-based composites is poor anti-aging performance. The main reason is the ultraviolet radiation in the 280-400nm band of solar radiation. The damage to the resin-based composites is very serious. Degradation of polymer chains causes rapid degradation of resin-based composites. The fumed nano-silica can strongly reflect ultraviolet rays, and the addition to the epoxy resin can greatly reduce the degradation of the epoxy resin by the ultraviolet rays, thereby achieving the purpose of delaying the aging of the material.
