The manufacturer tells you the scope and application of the composite well cover

The molding process of composite materials is flexible, and its structure and properties are highly designable. The structural strength of various components can be improved by one-step molding. The performance of different parts of components can be improved by the design of fiber types and different arrangement. By adjusting the composition, composition and arrangement of each component of the composite material, the component can not only bear different forces at different positions, but also can be made into composite multifunctional products with contradictory properties such as rigidity, toughness and plasticity, which are the advantages that traditional materials do not have. In the application technology of composite evacuation platform and cable support, the “designability” of composite performance plays an important role.

However, the corrosion resistance of the original metal materials has been difficult to solve, such as the corrosion of various metal cable supports and components in humid environment, acid rain, salt spray and so on. When applied to the underground environment with obvious marine climate in Guangzhou, the corrosion hazard is more obvious. Coupled with the stray current corrosion of subway engineering, the service life of metal materials is greatly reduced.

The composite well cover has high strength, low price and beautiful appearance. Can be any coloring, installation, maintenance, identification is convenient, because no recycling value, completely solve the problem of anti-theft. In the next three to five years, China will gradually replace the composite manhole covers, and the market potential is unprecedented.

Fiber reinforced materials are widely used and used in composites. For example, the specific strength and specific modulus of carbon fiber / epoxy resin composites are several times higher than those of steel and aluminum alloy. They also have excellent chemical stability, friction and wear resistance, self lubrication, heat resistance, fatigue resistance, creep resistance, noise elimination, electrical insulation and other properties. The composite of graphite fiber and resin can obtain the material with expansion coefficient almost equal to zero. Another characteristic of fiber reinforced materials is anisotropy, so the arrangement of fibers can be designed according to the strength requirements of different parts of the parts. The aluminum matrix composites reinforced with carbon fiber and silicon carbide fiber can maintain enough strength and modulus at 500 ℃.
