Description

[0001] Technical field: [0002] The present invention relates to composite materials, in particular to vinyl resin-based composite materials and methods for their preparation. [0003] Background technique: [0004] Vinyl resin is an unsaturated polyester resin with a special structure that is soluble in styrene liquid and contains unsaturated double bonds. It has good corrosion resistance and is superior to m-benzene type unsaturated resin. Its mechanical properties are similar to those of standard epoxy resins. Vinyl resin is comparable, especially in fatigue resistance and dynamic load performance; in addition, compared with general resins, vinyl resin has good weather resistance, in addition to good glass fiber impregnation performance and process performance, suitable for various FRP molding process, including various composite material processes such as filament winding, pultrusion, hand lay-up, and spraying. Vinyl resin is a resin with excellent corrosion resistance de...
