Characteristic properties of FRP

2014-08-06

Good corrosion resistance
Fiberglass (FRP) is a good corrosion resistance of composite materials, air and water oxidation as well as a variety of solvents, such as pH and salt concentration in general has a strong resistance, has been applied to all aspects of environmental protection, chemical corrosion, is gradually replacing carbon steel, stainless steel, wood, non-ferrous metals.

Lightweight, high strength

The relative density of between 1.5 to 2.0, only steel 1/4 to 1/5, but the tensile strength is close, even more than carbon steel, alloy steel and can be compared with the high specific strength. Thus, in aviation, rockets, spacecraft, high-pressure containers and other products needed to reduce the weight of applications, both with excellent results. Some epoxy FRP tensile, flexural and compressive strength can reach 400Mpa or more.

Good insulation properties

Is an excellent insulating material for manufacturing the insulator. Still under the protection of a good high-frequency dielectric properties. Microwave permeability is good, has been widely used in the radome.

Good thermal performance

FRP low thermal conductivity at room temperature of 1.25 ~ 1.67kJ / (m · h · K), only the metal of 1/100 to 1/1000, is an excellent insulating material. In the case of transient ultra-high temperature is ideal and ablative thermal protection material, to protect spacecraft withstand high-speed airflow above 2000 ℃ erosion.

Can be designed and strong

1, according to need, the flexibility to design a variety of structural glass and steel products to meet the requirements, with good integrity.
2, the material can be sufficiently selected to meet the properties of the product, such as: corrosion may be devised, and the instantaneous high temperature resistance, particularly high strength in a certain direction on the product, good dielectric properties, and the like.

Excellent craft
1, may be the flexibility to choose according to the shape of the molding process, technical requirements, uses and quantity of products.
2, the process is simple, once formed, the economic effect is prominent, especially for complex shapes, easy molding of a small number of products, but also highlight its technology superiority.
