A Short Review on Basalt Fiber

A hard, dense, inert rock found world wide, basalt is an igneous rock, wh ich is solid ified volcanic lava. Cast basalt liners for steel tubing shows very high abrasion resistance in various industrial applications. In recent years, continuous basalt fibers ext ruded fro m naturally fire-resistant basalt are attracted attention as a rep lacement fo r asbestos fibers. In the last decade, basalt has emerged as a contender in the fiber reinforcement of co mposites. Some manufacturer of basalts claims it offers performance similar to S-2 glass fibers at a price point between S-2 glass and E-g lass, and may offer manufacturers a less -expensive alternative to carbon fiber. Basalt fibre (BF) is capable to withstand very high temperature and can act as fire blocking element.
