Glass fiber reinforced plastic (GFRP) is a type of fiber-reinforced composite material. It has the characteristics of light weight, high strength, corrosion resistance, easy cutting and non-magnetic.
It is widely used in road bridge deck paving, foundation pit construction, coastal engineering, tunnel construction, subway diaphragm walls, retaining piles, etc.
Fiber-reinforced composite materials are materials formed from high-performance fibers, synthetic resin matrices, and curing agents using appropriate molding processes; high
Performance fiber is the reinforcing material, and synthetic resin is the matrix material. The fiber has high tensile strength and is the main provider of strength for glass fiber bars.
It mainly plays the role of bearing load. The matrix material has the function of bonding and transmitting shear force. Its physical properties can affect the physical properties of fiber reinforced materials.
