INTRODUCTIONNew materials offer the promise of innovative applications in airtransportation. one such new material is basalt fiber, basalt is a hard,dense, dark volcanic rock composed chiefly of plagioclase, pyroxene,and olivine, and often having a glassy appearance. the name "basalt"is usually given to a wide variety of dark-brown to black volcanic rocks,which form when molten lava from deep in the earths crust rises upand solidifies. basalt can be formed into continuous fiber havingunique mechanical and chemical properties.Use of basalt fiber in air transportation, requires a better knowledgeof many properties. the basalt fibers as reinforcing materials has tobe examined in epoxy and polyster matrix.
OVERVIEW OF WORK ON BASALT FIBERS For many years, basalt has been used in casting processes to make tiles and slabs for architectural applications. additionally, cast basalt liners for steel tubing exhibit ver y high abrasion resistance in industrial applications. in crushed form, basalt also finds use as aggregate in concrete. More recently, continuous fibers extruded from naturally fire- resistant basalt have been investigated as a replacement for asbestos fibers, in almost all of its applications. in the last decade, basalt has emerged as a contender in the fiber reinforcement of composites. proponents of this late-comer claim their products offer per formance similar to s-2 glass fibers at a price point between s-2 glass and e-glass, and may offer manufacturers a less-expensive alternative to carbon fiber for products in which the latter represents over-engineering.

PROPERTIES OF BASALT FIBERBasalt fibers possess several good properties which make it possible to use them as areinforcement in composites.•corrosion resistant,•strength, elasticity properties of basalt fibers considerably exceed mineral and glassfibers.•Due the elasticity of micro- and macrostructure, basalt fibers are vibration-resistantcompared to similar products•Environmentally and ecologically harmless•free of carcinogens and other health hazards.•heat and sound isolation,•vibration damping,•High strength• High modulus•Corrosion resistance•High temperature resistance•Extended operating temperature range
