High-strength glass fiber, also known as S-glass fiber, is about 35% higher in strength than E-glass fiber, about 10-20% higher in elastic modulus, and has a temperature resistance of more than 800 degrees. High-strength glass fiber has excellent tensile strength and elastic modulus, and has been widely used in aerospace, weapons, nuclear energy, and high-end industrial equipment fields, such as aircraft radomes, missile housings, bulletproof helmets, helicopter rotors, etc.
