Properties of SMC Composites Material,SMC (Sheet Molding Compound) composite material is a high-performance composite material composed of fiber-reinforced resin and filler, which has many excellent performance characteristics,it is compression molding process.
Sheet molding compound is a reinforced polyester containing glass or carbon fibers. Fibers, typically 1 inch or more in length, are suspended in a bath of resin, usually epoxy, vinylester, or polyester. The combination of long fibers and ultra-high-strength resins produces strong, economical materials.
Some main properties of SMC composite materials
1. Strength and stiffness
SMC composite materials have excellent strength and stiffness, and can withstand large loads without being easily deformed or broken. This makes it widely used as a structural material in many applications.
2. Lightweight-Properties of SMC Composites Material
Despite their high strength and stiffness, SMC composites are still lighter than many traditional metal materials, which helps reduce structural loads and improve energy efficiency.
3. Corrosion resistance
SMC composite materials have excellent corrosion resistance in many chemical environments, and can resist the erosion of acid, alkali, salt and other corrosive media, thus prolonging the service life of the material.
4. Thermal stability
SMC composite materials maintain stability under high temperature conditions and are not easy to soften or melt. This makes it suitable for applications in high temperature environments such as hoods, chimney covers, etc.
5. Insulation properties
SMC composite materials have good electrical insulation properties, can be used in electrical and electronic equipment, and also help prevent electromagnetic interference from electric heating equipment.
6. Sound absorption and heat insulation
SMC composite materials have good sound absorption and heat insulation properties, and can play a role in noise control and temperature regulation.
7. Mold forming
SMC composite materials can be molded into various complex shapes and sizes to achieve design flexibility and diversity.
8. Good appearance performance
The surface quality of SMC composite materials is good, which can achieve a smooth and beautiful appearance and reduce subsequent surface treatment processes.
9. Fatigue resistance
SMC composites exhibit good fatigue resistance, that is, fatigue cracking is not easy to occur under long-term cyclic loading.
10. Recyclability
Some components in SMC composites can be recycled, helping to reduce waste generation and reduce environmental impact.
To sum up, SMC composite materials have been applied in many fields due to their excellent performance characteristics, from automobile manufacturing, construction, electrical equipment to aerospace, etc., can give full play to their advantages.
The production method of SMC can guarantee the complete fusion of fiber and resin. The resin is applied to the film in paste form; next, the fibers are chopped and added to the paste. The material is then squeezed between two films; compacted until the desired thickness and texture are achieved. The correct sheet molding compound must be stored for several days before curing until it can be sold and used. It is important to note that the material does not fully cure during storage, and when heat and pressure are applied to it, the final cure will take place in the mold.
SMC is usually sold in rolls, cut into small pieces, called charges. Heat and pressure are applied to the charge through a process called compression molding, resulting in anything from simple designs to complex parts.
