What is the difference between GRP and SMC composite materials?

GRP, commonly known as fiberglass, and SMC, also known as sheet molding compound, differ mainly in material and function.
common ground:
GRP/SMC composite material buckle plate, the main functional features of the product are high strength, toughness, antibacterial, fireproof, moisture-proof, anti condensation, acid and alkali resistance.
difference:
1. Material
The matrix of GRP material is resin, which plays a bonding role. Resin is a thermosetting plastic, including epoxy and phenolic resins, and it is also an organic non-metallic material.
SMC is mainly composed of specialized yarn, unsaturated resin, low shrinkage additives, and various additives.
2. Function
The reinforcement of GRP material is glass fiber, which plays a reinforcing role.
The unique properties of SMC composite materials solve the disadvantages of aging, corrosion, poor insulation, cold resistance, poor flame retardancy, and short service life of wooden, steel, and plastic meter boxes. The excellent performance of composite meter boxes includes absolute sealing, waterproof, anti-corrosion, and anti-theft properties.
