Glass fiber is a micron-sized fibrous material made of glass by pulling or centrifugal force after high-temperature melting, and its main components are silica, calcium oxide, alumina, magnesium oxide, boron oxide, sodium oxide, and so on. There are eight types of glass fiber components, namely, E-glass fiber, C-glass fiber, A-glass fiber, D-glass fiber, S-glass fiber, M-glass fiber, AR-glass fiber, E-CR Glass Fiber.
E-glass fiber, also known as alkali-free glass fiber, has high mechanical strength, good heat resistance, water resistance, and electrical insulation, commonly used as electrical insulation materials, also used in the production of glass fiber reinforced plastic reinforcing materials, but poor acid resistance, easy to be corroded by inorganic acids.
C-glass fiber has high chemical stability, acid resistance, and water resistance better than alkali-free glass fiber, but the mechanical strength is lower than E-glass fiber, electrical performance is poor, used in acid-resistant filtration materials, can also be used in chemical corrosion-resistant glass fiber reinforced materials.
A-glass fiber is a class of sodium silicate glass fiber, its acid resistance is good, but poor water resistance can be made into thin mats, woven pipe wrapping cloth, and so on.
D-glass fibers, also known as low dielectric glass fibers, are mainly composed of high boron and high silica glass, which has a small dielectric constant and low dielectric loss and is used as a substrate for radome reinforcement, printed circuit board substrate, and so on.
S-glass fibers and M-glass fibers are widely used in aerospace, military, and environmental applications due to their high strength, high modulus, good fatigue resistance, and high-temperature resistance.
AR-Glass fiber is resistant to alkali solution erosion, has high strength, and good impact resistance, used as reinforcing cement.
E-CR fiberglass is a type of alkali-free glass but does not contain boron oxide. It has higher water resistance and acid resistance than E-glass, and significantly higher heat resistance and electrical insulation, and is used for underground piping and other materials.
Glass fiber has good heat resistance and chemical stability, high tensile strength, high elastic touch, low dielectric constant, small thermal conductivity, impact resistance, corrosion resistance and fatigue resistance, and functional designability. However, brittleness is large, poor abrasion resistance, and softness is poor Therefore, glass fiber needs to be modified processed, and compounded with other related materials to meet the needs of aviation, construction, environment, and other fields.
