High-strength glass fiber

- Jul 15, 2019-

It is characterized by high strength and high modulus. Its single fiber tensile strength is 2800 MPa, which is about 25% higher than that of alkali-free glass fiber. The elastic modulus is 8600 MPa, which is higher than that of E-glass fiber. The FRP products produced by them are mostly used in military, space, bulletproof armor and sports equipment. However, due to the high price, it is still not popularized in civilian use, and the world's output is about several thousand tons.
