Why choose fiberglass?
Glass fiber fabrics have many unique and outstanding properties, and provide design opportunities for improving existing products and developing new, lightweight, and cost-effective composite material products. Simply put, glass fiber has the following excellent properties:
Chemical resistance
Inorganic glass fiber textile fibers do not decay, mold, or deteriorate. In addition to hydrofluoric acid and hot phosphoric acid, they can also resist most acids.
dimensional stability
Due to changes in atmospheric conditions, the glass fiber yarn used for manufacturing glass fabrics will not stretch or shrink. The nominal elongation at break is 3-4%. The average linear thermal expansion coefficient of block E glass is 5.4 × 10-6cm/cm/℃.
Good thermal performance
Glass fiber fabrics have a lower coefficient of thermal expansion and higher thermal conductivity. Glass fibers dissipate heat faster than asbestos or organic fibers.
High tensile strength
Glass fiber yarn has a high strength to weight ratio. A pound of fiberglass yarn has twice the strength of steel wire. The ability to design unidirectional or bidirectional strength in fabrics greatly increases the flexibility of end-use products.
High heat resistance
Inorganic glass fibers do not burn and are basically unaffected by the high baking and curing temperatures commonly encountered in industrial processing. Glass fiber will maintain approximately 50% of its strength at 700 ° F and 25% of its strength at 1000 ° F.
Low moisture absorption
Glass fiber yarn is made of non porous fibers, so its moisture absorption is extremely low.
Excellent electrical insulation
High dielectric strength and relatively low dielectric constant, as well as low water absorption and high temperature resistance, make glass fiber fabrics excellent in electrical insulation.
Product flexibility
The extremely fine filaments used in glass fiber yarns, with various yarn sizes and configurations, different weaving types, and many special finishes, make glass fiber fabrics suitable for a wide range of industrial end uses.
low cost
Glass fiber fabrics can be competent and can be compared in cost with synthetic and natural fiber fabrics.
Therefore, glass fiber is an ideal reinforcement material, cost-effective, and easy to operate, making it one of the most widely used materials among many reinforcement materials.
