Pre-oxidized fiberglass aluminum-coated fabric is a high-performance composite material specially designed for protection and insulation applications in extreme environments. This material combines the excellent properties of pre-oxidized fiber, glass fiber and aluminum coating to form a fabric with high flame retardancy, high temperature resistance, corrosion resistance and high strength.
Pre-oxidized fiber:
Basic ingredients: Pre-oxidized fiber is a material obtained by pre-oxidizing polyacrylonitrile (PAN)-based carbon fiber at high temperature. The pre-oxidized fiber has high thermal stability and flame retardancy. This process carbonizes the fiber without burning, thus having natural flame retardancy.
Features: Pre-oxidized fiber is not easy to burn and will not produce molten droplets at high temperatures. It is suitable for use in environments with high temperature and high fire risks.
Glass fiber:
Basic ingredients: Glass fiber is an inorganic fiber with silica as the main component, which is made by melt drawing process. Glass fiber has excellent mechanical properties, including high strength and high modulus.
Features: Glass fiber is resistant to high temperatures, corrosion, tensile and lightweight, and is widely used to enhance the strength and durability of composite materials.
Aluminum Coating:
Basic ingredients: The aluminum coating is a layer of aluminum film coated on the surface of the pre-oxidized fiberglass substrate. This aluminum film can be achieved through physical vapor deposition (PVD) or other aluminum plating processes.
Features: Aluminum has high reflectivity and can effectively reflect infrared and ultraviolet thermal radiation. In addition, the aluminum film also has good anti-oxidation and anti-corrosion capabilities.
Pre-oxidized fiberglass aluminum-coated fabric performance
- Flame retardancy: Pre-oxidized fiber exhibits excellent flame retardancy at high temperatures. Even when exposed to open flames, it will not burn or drip. This material does not produce toxic gases, making it very suitable for protective applications that require high safety.
- High temperature resistance: Glass fiber can withstand temperatures of up to 700°C, and the coated aluminum layer further enhances the material's high temperature resistance. The reflective properties of the aluminum film can also effectively reduce the surface temperature, thereby protecting the internal structure.
- Heat reflection and insulation performance: The high reflectivity of the aluminum film enables the material to effectively reflect most of the heat radiation, thereby reducing the conduction of heat. This property makes the fabric suitable for use as a thermal barrier or to protect equipment from high temperature environments.
- Corrosion and chemical resistance: The aluminum film has good resistance to chemicals such as acids and alkalis, making the fabric perform well in corrosive environments such as chemical plants. At the same time, the glass fiber itself is also corrosion-resistant, enhancing the overall durability of the material.
- Mechanical strength: Glass fiber provides high strength and low weight, allowing the material to have excellent tensile and tear resistance while remaining lightweight. Combined with the high temperature stability of pre-oxidized yarn, the material can still maintain mechanical integrity under extreme conditions.
Application scenarios of pre-oxidized fiberglass aluminum-coated fabrics
