GFRPis a new kind of composite material,which is glass fiber as reinforcement material,combines with epoxy (resin) and curing agent, then through pultrusionMolding process.
Advantage:
1. High corrosion resistance—The fiberglass used by the rebar are durable materials, and they are molded through the composite process. The life span is up to 100 years. They can be used as permanent support materials.
2. High tensile strength—The load is approximately double that of a steel bar with the same diameter
3. Low weight—The weight is only 1/4 that of a steel bar with the same diameter, therefore, the labor intensity is greatly reduced, and the transportation cost is reduced at the same time
4. Anti-static—It has no electrical conductivity, and no sparks will be produced when being cut, it’s particularly suitable for high gas zones;
5. Non-flammable—It’s non-flammable and has high thermal isolation;
6. Cuttability—It avoids damages to cutter heads, and does not delay excavation
7. Save cost—Use this material as reinforcing bars for road and bridge, could reduce secondary repair cost.
Applications:
Such as,construction, transportation industry,coal mine tunnel,parking structures, half coal roadway, slope support, subway tunnel, rock surface anchoring, sea wall and dam etc.
