Basalt fiber 【product description】 Basalt fiber untwisted roving is a bundle formed by combining multiple parallel strands or single strands of parallel strands in an untwisted state. The tensile strength of 7-13μm untwisted roving is ≥0.65N/tex, t he modulus of elasticity is ≥95GPa, and the elongation at break is ≥2.6%. Basalt fiber not only has high strength, high modulus and impact resistance comparable to high-tech fibers such as PPTA (poly-p-aniline terephthalamide) and UHMWPE (ultra-high molecular weight polyethylene), but also has high temperature resistance and light resistance. It is good, especially the bonding strength of the interface combined with resin is very high, so various specifications of basalt roving can be used to weave, wind, and weave various composite material preforms. 【Application field】 1. Weaving unidirectional fabrics of various specifications for building reinforcement; 2. Winding various tubes, tanks and gas cylinders; 3. Weaving all kinds of checkered cloth, grid cloth and geotextile; 4. Building repair, reinforcement, high temperature resistant SMC (sheet molding compound), BMC (block molding compound), DMC (bulk molding compound), chopped fiber for road use; 5. Cooperate with resin to strengthen materials, etc.
