What is FRP? |
|
| FRP is a compound of Fiber Glass and resin. |
|
|
FRP Compositions |
|
1) Resin: Unsaturated Polyester Resin, Epoxy Resin, Vinly Ester Resin, Phenolic Resin
2) Fiber Glass
3) Hardener
4) Filler

Advantages |
|
| ① Light and high strength |
Specific gravity is 25% of iron, 60% aluminum |
| ② non-corrosive |
Does not rust or rot.
Stronger than other plastics in water, grease and chemicals. |
| ③ Fine Casting |
Particular facility is not necessary and coloring is possible. |
| ④ Excellent heat transfer |
Fine electric wave permeability.
High in strength (used for aircraft and vessel surfaces and radar domes. |
| ⑤ Heat Resistant |
Heat insulation effect (refrigerator, container (fish))
specific heat: 2-3 times to metal.
Thermal conduction rate: 2-3 times less to metal. |
| ⑥ Permeability is possible |
Light is scattered. When applied to a greenhouse provides light in all directions helping plant growth. |
|
|
Disadvantages |
|
| ① Low modulus |
Lower rigidity compared to iron-aluminum-metal. |
| ② Low heat resistance |
Tested in high temperature for hours, general FRP: about 100℃, heat resistance resin: about 160℃ |
| ③ Combustible |
This resin is a combination of carbon, so to increase autolysis a non-combustible resin is added. |
