Landscape frp sculpture

The relative density is between 1.5 and 2.0, only 1/4 to 1/5 of carbon steel, but the tensile strength is close to, or even more than carbon steel, and the specific strength can be compared with alloy steel. As a result, it has excellent results in aerospace, rockets, space vehicles, high-pressure vessels, and other applications that require self-weight reduction. Some epoxy FRPs can reach tensile, bending and compressive strengths of more than 400Mpa. The density, strength and specific strength of some materials are shown in Table 1-1.

Second, the corrosion resistance is good

FRP is a good corrosion resistant material with good resistance to the atmosphere, water and general concentrations of acids, alkalis, salts, and a variety of oils and solvents. It has been applied to all aspects of chemical corrosion protection and is replacing carbon steel, stainless steel, wood, non-ferrous metals, etc.

Third, the electrical performance is good

It is an excellent insulating material used to make insulators. Good dielectricity is still protected at high frequencies. Microwave transmission is good, has been widely used in radar radomes.

Fourth, the thermal performance is good

FRP has low thermal conductivity, 1.25~1.67kJ/(m·h· K), only 1/100 to 1/1000 of the metal, is an excellent thermal insulation material. In the case of instantaneous ultra-high temperature, it is an ideal thermal protection and ablation resistance material, which can protect the spacecraft from the erosion of high-speed air flow above 2000 °C.

Fifth, good designability

Not only can you flexibly design a variety of structural products according to your needs to meet the requirements of use, but also make the product have a good integrity. You can also fully select materials to meet the performance of the product, such as: can be designed to resist corrosion, resistant to instantaneous high temperatures, the product has a particularly high strength in a certain direction, good dielectricity, and so on.

Sixth, excellent craftsmanship

The molding process can be flexibly selected according to the shape, technical requirements, application and quantity of the product. The process is simple, can be molded at one time, the economic effect is outstanding, especially for products with complex shapes and small quantities that are not easy to form, and its craftsmanship is more prominent.
