stone mountain carving is a finished type of stone carving. stone mountain carving has the characteristics of light weight, corrosion resistance and relatively low cost. stone mountain carving is also called FRP, scientifically called fiber reinforced plastic, and it is customary in China to call it stone mountain carving. It is a composite material composed of synthetic resin as the matrix material and stone fiber and its products as reinforcing materials.
Stone carving is hard and brittle, has good transparency, high temperature resistance and corrosion resistance. At the same time, steel is hard but not brittle, and it is also resistant to high temperatures. So people began to think that if a material could be produced that not only had the hardness, high temperature resistance, and corrosion resistance of stone carving, but also had the characteristics of being as hard and unbreakable as steel, then this material would be of great use. The material of stone mountain carving came into being and has been used very well in stone mountain carving. The relative density of stone mountain carving is between 1.5 and 2.0, which is only 1/4 to 1/5 of carbon steel. However, the tensile strength is close to or even exceeds carbon steel, and the specific strength is comparable to alloy steel. Therefore, it has excellent effects in products that need to reduce their own weight, such as aviation, rockets, spacecraft, and high-pressure vessels. The tensile, bending and compressive strength of some epoxy
stone sculpture can reach more than 400Mpa.
The working pressure of stone mountain carving in stone mountain carving is 150kg/cm2. For safe use, it is required to withstand three times the working pressure during manufacturing, that is, 450kg/cm2. If it does not burst, it is considered qualified. The oxygen cylinders tested above far exceeded the design requirements. What steel is this made of? It's stone fiber, more precisely, it's made of stone and plastic. stone mountain carving in stone mountain carving is an excellent insulating material used to make insulators. It maintains good dielectric properties at high frequencies. It has good microwave penetration and has been widely used in radar radomes. The process is simple, one-time molding, and the economic effect is outstanding. Especially for products with complex shapes and small batches that are difficult to mold, the process advantages are even more prominent. The thermal conductivity of stone carving is low, 1.25~1.67kJ/(m·h·K) at normal temperature, which is only 1/100~1/1000 of metal. It is an excellent thermal insulation material. Under the condition of instantaneous high temperature, the stone mountain carving in the stone mountain carving is an ideal thermal protection and anti-ablation material, which can protect the spacecraft from being washed by high-speed airflow above 2000°C.
