GRP Characteristics
◆ Unique Composition:
Fiber-reinforced polymer (FRP) composites differ from traditional construction materials like steel or aluminum. These composites primarily consist of fibers and resin, with the fibers enhancing the properties of the resin matrix through fibrous reinforcement principles.
◆ Resin Functionality:
The resin acts as a binding agent, holding the fibers together, transferring stress between them, and protecting them from mechanical and environmental damage.
◆ Material Variety:
○ Fibers: Commonly used fibers include fiberglass, carbon fiber, aramid fiber, and basalt fiber.
○ Resins: Production involves polyester, epoxy, and phenolic resins.
◆ Customizable Properties:
By altering the fiber and resin combination, their respective ratios, and the fiber distribution and orientation, GRP products can be tailored to deliver specific properties and meet diverse application needs.
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 Systems and Their Characteristics
Resin | Property |
Unsaturated Isophthalic Polyester (ISO UP) | ○ Properties: The most commonly used resin system, offering good mechanical strength and corrosion resistance. |
Vinyl Ester (VE) | ○ Properties: Superior corrosion and heat resistance compared to Polyester resin. Stronger and more durable. |
Epoxy (EP) | ○ Properties: Excellent strength, electrical insulation, and resistance to low temperatures. |
Acrylic (AC) | ○ Properties: High-grade fire-retardant properties with low smoke and toxicity emissions. |
Polyurethane (PU) | ○ Properties: Exceptional shearing and transverse strength. |
