Basalt is a mineral of volcanic origin, dark or black. It is a heavy, tenacious and resilient rock. Its density is approximately 5% higher than that of glass.
Basalt fiber results from the treatment of basaltic rock, composed of minerals such as plagioclase, pyroxene and olivine. As a by-product of basalt's own casting process (single ingredient used in fiber production), basalt fiber is of superior quality to other known fibers for thermal stability, heat and sound insulation, vibration, durability and lightness, that is, in a summary form, it can be said that basalt fiber is a type of fiber with better performance with regard to the physical-mechanical properties.
Basalt fiber has recently developed compared to the traditional fibers used in the manufacture of polymer composites, such as glass fiber, carbon fiber and aramid. Its strength and modulus properties are located between those recorded by the E-glass fiber and S-glass fiber. In addition, they have a higher working temperature, good chemical and impact resistance, corrosion resistance and less release of gases in the burning.
The low price of basalt fiber, which may be lower than that of fiberglass-E, justifies the increasing use of this fiber. For these reasons, basalt fiber is increasingly used in a wide range of applications, including the manufacture of pressure vessels, cylinders, profiles, automotive parts, wind turbines, reinforcing concrete structures, fireproof textile material (in aerospace and automotive industries), marine applications, military industry, aerospace industry, and various other products and fields of application.
The use of basalt in the manufacture of composite materials has many unparalleled advantages. This results in the use of composites to optimize the properties of materials, including mechanical, chemical and physical properties, as well as thermal, electrical, optical and acoustic properties. Due to its high strength and lightness, resulting from the physico-mechanical properties of basalt fiber, the composite materials thus have a wide field of industrial application.
The use of basalt fiber as a reinforcement of composite polymer matrix materials is relatively recent compared to the known glass and carbon fibers. The first attempts to produce Basalt Fiber go back to the year 1923, when the Frenchman Paul Dhé registered in the USA the first patent for continuous filaments of basalt. After World War II, researchs were developed in the USA, Europe and the former Soviet Union to obtain extruded fibers and to study the first applications in the military and aerospace fields. It was only after 1990-1992, with Perestroika, that this technology came to be in the public domain and, consequently, boosted research on the civilian application of basalt fiber.
It is in this context that framed by the International Conference under the theme "APPLICATION OF BASALT POWDER IN AGRICULTURE AND INDUSTRY - Its advantages as Fertiliser and Reinforcement of Composite Materials", the fourth theme of the Conference is included as part of the event: "THE ROLE OF BASALT FIBER IN INDUSTRIAL INNOVATION: RUSSIA as Case Study in the industrial application of basalt powder".
