Composite materials 
 To high-strength glass fiber reinforced materials, synthetic resin as matrix material, and mixed with appropriate adjuvant composite made of composite material, known as glass fiber reinforced plastic (Abbreviation: frp) commonly known as glass fiber reinforced. 
 Applications 
 1, can be widely used in highways, bridges, airports, terminals, stations, water conservancy, underground engineering and other fields 
 2, suitable for sewage treatment plants, chemical plants, cell, manhole cover, coastal engineering and other corrosive environments 
 3, suitable for military engineering, security engineering, special projects off the magnetic environment to be insulated. 
 Features 
 High tensile strength: tensile strength than ordinary steel, reinforced with the specifications than 20%, and good fatigue resistance; 
 Light weight: only reinforced with the same volume of 1 / 4; density of 1.5-1.9 (g/cm3) between. 
 Corrosion resistance: acid and other chemicals, and corrosion resistant to chloride corrosion of low ph value of the solution, especially anti-carbon compounds and chlorine compounds, more corrosive; 
 Combination of strong material: thermal expansion coefficient closer than cement and steel, so frp reinforcement and concrete with a stronger bond strength; 
 Can design and strong: the elastic modulus and stability. Dimensional stability under thermal stress, bending and other shapes can be any hot forming; safety performance is good, not thermal, non-conductive, flame-retardant anti-static, the collision with the metal through the formulation change does not produce sparks; 
 Strong magnetic properties through: frp reinforcement is a non-magnetic material, the non-magnetic or electromagnetic components in the concrete need to do off the magnetic treatment; 
 Construction is convenient: users can request the production of different cross sections and the length of the standard and non-standard parts, the scene binds non-metallic tension band can be easy to operate
