stone mountain carving generally have an outdoor lifespan of 8-10 years, which of course requires production. The required quantity of stone sculpture fibers and the thickness and symmetry of the entire stone sculpture must be achieved. The paint on the surface protective layer also has a lot to do with it. If general nitrocellulose paint is used outdoors, it is estimated that the surface color will need to be repaired in less than two years.
The material of
stone carving is fiber reinforced plastic, which is scientifically known as stone carving. It uses stone fiber and its products (stone cloth, belts, felt, yarn, etc.) as reinforcing materials. It is a composite material with synthetic resin as the matrix material. The concept of composite materials means that one material cannot meet the requirements of use, and two or more materials need to be combined together to form another material that can meet people's requirements, that is, composite materials.
For example, although a single type of stone fiber has high strength, the fibers are loose and can only bear tensile force, but cannot bear bending, shearing and compressive stress. It is not easy to be made into a fixed geometric shape and is a soft body. If they are bonded together with synthetic resin, they can be made into various hard products with fixed shapes, which can withstand not only tensile stress, but also bending, compression and shear stress. This constitutes a fiber-reinforced plastic matrix composite material.
Because its strength is equivalent to steel, it also contains stone carving components, and it also has the color, shape, corrosion resistance, electrical insulation, heat insulation and other properties of stone carving. Like stone carving, it formed the easy-to-understand name "stone mountain carving" , this term was proposed by Comrade Lai Jifa, the former Minister of the Ministry of Building Materials Industry, in 1958. Expanding from the building materials system to the whole country, the meaning of stone carving refers to reinforced plastics with stone fiber as reinforcing material and synthetic resin as binder. Abroad, it is called stone fiber reinforced plastic.
With the development of my country's stone mountain carving industry, the plastic-based reinforcing materials have expanded from stone fiber to carbon fiber, boron fiber, aramid fiber, alumina fiber and silicon carbide fiber. Undoubtedly, reinforced materials made of these new fibers Plastics are some high-performance fiber-reinforced composite materials, and the common name of stone mountain carving cannot be summarized. Taking into account the historical origin and development, stone mountain carving composite materials are usually used for such a name.
