GRP CHARACTER
◆ Fiber reinforced polymer composites are different from traditional construction materials such as steel or aluminum. Composite is composed mainly by fibers and resin. The fiber employs the fundamental principles of fibrous reinforcement to improve the properties of the matrix contained in the reinforcement.
◆ The resin acting as a glue holds the fiber together to transfer stress between the reinforcing fibers, and protects the fibers from mechanical and environmental damage.
◆ The fibers used in the production are fiberglass, carbon fiber, aramid fiber and basalt fiber. The resins used in the production are polyester, epoxy and phenolics.
◆ Products of certain properties and usage can be produced by changing the combination of fibers and resin, the ration between fibers and resin, and the distribution and direction of fibers.
ADVANTAGES OF GRP
High Strength
Higher strength than structure steel on a weight to weight ratio.
Impact Resistance
Return to original position without any permanent deflection or distortion.
Light Weight
Average 15% to 20% that of steel products.
Corrosion Resistance
Not susceptible to rusting, peeling nor flaking and impervious to a broad range of corrosive elements.
Non-conductive
Low thermal conductivity and non-conductive.
Electro-magnetic Transprency
Transparent to radio waves, microwaves and other electromagnetic frequencies.
Dimensional Stability
Marginally low coefficient of thermal expansion than steel and aluminum.
Low Temperature Performance
Excellent mechanical properties at low temperatures.
RESIN SYSTEM
Resin | Property |
Unsaturated Isophthalic Polyester (ISO UP) | This is the most widely used resin system. It offers good mechanical and corrosion resistance properties. |
Vinyl Easter (VE) | Vinyl Ester resin offers better corrosion and heat resistance, and stronger than Polyester resin. It is widely used in industries using heavy chemical and caustic materials. |
Epoxy (EP) | Offers very good strength, electrical properties, low temperature resistance. |
Acrylic (AC) | This resin provides high grade fire-retardant, and low smoke and toxicity properties. It is widely used in enclosed areas, mass transit and tunnel application. |
Polyurethane (PU) | Offers very good shearing and transvers strength properties. Easy to discoloring under weathering is its disadvantage |
