FRP, refers to Fiber Reinforced Polymer(Plastic).Existing include G(lass)FRP/ B(asalt)FRP/C(arbon)FRP/A(ramid)FRP and so on.GFRP is common known as the Glass Fiber Reinforced Polymer(Plastic).
FRP is a new high performance material which made ofreinforced fiber with matrix resin by certain proportion formation. It’s couldachieve features of various kinds of applications requirement with differentresin. Matrix resin include Unsaturated Polyester, Epoxy, Vinyl-esterand Polyurethane resin etc.
Originally, invention of FRP is in order to solvethe problem of steel rebar corrosion. As tech development, FRP materialsderived a wide variety of products, could used in mining roadway, transit,coastal, municipal construction and other applications.
Comparison ofFRP and steel rebar
Steel | GFRP | BFRP | CFRP | |
Densityg/cm³ | 7.85 | 1.9-2.1 | 1.9-2.1 | 1.25 |
Tensile Strength (MPa) | 400-800 | 600-1000 | 700-1500 | 1500-2500 |
E-modulus(GPa) | 200 | >40 | >45 | >124 |
