Description

technical field [0001] The invention relates to a composite material, in particular to an anti-ultraviolet aging fiber-reinforced polymer-based composite material, which belongs to the technical field of functional polymer composite materials. Background technique [0002] Fiber-reinforced polymer matrix composites (FRP) are a type of composite materials composed of matrix resin and reinforcing fibers, which have the advantages of light weight, high strength, corrosion resistance, and heat preservation. Has been widely used in building materials, chemicals, automobiles, shipbuilding, electrical and other industries. [0003] In practical applications, FRP can produce large-scale parts according to actual needs, and the matrix resin used is mostly thermosetting resin, such as epoxy resin and phenolic resin. As a resin-based composite material, aging phenomenon is still an important defect in the performance of this type of material. In particular, FRP products are often req...
