The application of SMC composite materials in explosion-proof electrical equipment shell products has changed the situation that the original explosion-proof electrical equipment shell products are mainly made of steel and aluminum. The application of SMC materials has overcome the defects that the explosion-proof electrical equipment steel and aluminum shells are bulky and easy to produce sparks due to collision. The application of SMC materials in explosion-proof electrical appliances in China is still in its infancy. The explosion-proof electrical equipment shell or mainly metal shell. SMC SMC materials have the advantages of excellent corrosion resistance, light weight, easy engineering design and good flexibility. Its mechanical properties can be compared with some metal materials. The properties of the composite materials can be designed by adjusting the formula, so that the SMC composite materials have a series of advantages such as antistatic, flame retardant, good thermal stability, high strength, corrosion resistance, long service life and high production efficiency, These performance advantages make SMC composite suitable for explosion-proof electrical equipment enclosures. In general, the development direction of aerospace composites is high-efficiency heat insulation technology, long-term low ablation technology, multi-functional technology, low-cost technology, etc. Carbon / carbon composites are mainly low-cost technologies and technologies to further improve ablation performance and ablation shape symmetry. Therefore, the replacement of cast iron products with polymer composites was studied. Many manhole covers made of waste plastics or other polymer composites have also appeared in the SMC material market. SMC material is made of polymer composite materials. The manhole cover series products must have the following advantages: high strength and stiffness; No deformation and fracture under thermal and stress conditions; High wear resistance and heat resistance; Good forming process, low shrinkage and good dimensional stability; Low forming pressure, simple manufacturing process, wide range of materials and low price; With non recyclable performance, anti-theft (non recyclable). SMC materials used in the production of manhole covers have quickly become the mainstream of such products because of their excellent performance. This product has been tested in many cities, and its performance has reached the performance of inspection well cover. At the same time, it is both environmentally friendly and anti-theft. It has a huge market and is worth promoting. Therefore, SMC materials have a good market prospect in the application of manhole covers in urban roads. Body and body components body shell, hard shell roof, floor, door, radiator grille, front panel, baffle, luggage compartment cover, sun visor, SMC radiator, engine cover, headlamp reflector. SMC composites and SMC molded products have excellent electrical insulation, mechanical properties, thermal stability, chemical resistance and corrosion resistance.
SMC materials therefore, SMC products have a wide range of applications, mainly in the following application fields:
1. Application of electrical industry. SMC material
2. Application in automobile industry
3. Application in railway vehicles
4. Application in communication engineering
5. Application of explosion proof electrical equipment shell
After more than 40 years of research and development and research and production of functional composites, CASM has gradually matured from the basic theory of raw material development and application, manufacturing technology and equipment, product performance testing and standard institutions. We have created a unique Aerospace functional composite technology system to meet the needs of different types of aerospace products, It has made great contributions to the development of China's aerospace industry. Sheet molding compound is an important and widely used semi-finished product and molding composite material. Compared with steel auto parts, SMC formed auto parts have the following advantages: short production cycle, easy to refit and good investment benefit; Lighter weight and fuel saving; Freedom of design; The integrity of parts is good, and the number of parts is small; Good durability and insulation.
