“…V. Dhand, Fiore V, Singha K. A [15][16][17], among others, believe that basalt fiber is an environmental protection natural fiber, which is very suitable to be used as a reinforcement material for manufacturing light and low-cost polymer composite materials, with higher cost-effectiveness and better performance than glass fiber. In addition to environmental protection, basalt fiber has the advantages of good chemical stability (acid and alkali resistance) [18,19] and high-temperature resistance [20], which is more suitable for use in an extreme environment.…”

The new sandwich composite structure formed by basalt fiber resin-based sheets and Nomex honeycomb has the advantages of being lightweight and environmentally friendly, as well as having excellent electromagnetic performance. It has very important application prospects in traditional and emerging fields. In this paper, the mechanical properties of this new sandwich composite structure are studied. The results show that, under the condition of flatwise compression, increasing the height of the honeycomb is conducive to improving the compressive capacity of the structure. However, the height should be controlled within a certain range in case of instability and yield of the honeycomb; under the bending conditions, the bending failure mode of the composite structure has gone through five stages. Owing to the honeycomb manufacturing process, the orientation of the honeycomb also has a great influence on the bending strength of the structure. After further analysis, it is found that basalt fiber sheets contribute the most to the bending stiffness of the structure, and the main role of honeycomb is to provide out-of-plane support. In both cases, the failure of specimens is ductile, and the combined structure still has a small amount of bearing capacity and maintains structural integrity. Research on this new type of composite structural material is very beneficial for promoting the application and development of green and lightweight special functional materials.

“…The most important components of basalt fiber are SiO 2 , Al 2 O 3 , Fe 2 O 3 , CaO and MgO [2]. It could be noted that tensile strength and heat resistance of basalt fiber samples can be improved by increasing the content of SiO 2 and Al 2 O 3 [22].…”

“…There have been relatively few systematic studies about dependency of the chemical and mechanical properties on the basalt fiber's chemical compositions or research of the initial raw materials [22], while at the same time, the very fact of such influence is generally recognized in community of basalt fiber producers. Considering that the chemical and mechanical properties of basalt fibers depend on the diameter of fibers, surface coatings and additives [41], as well as on the chemical compositions of the constituent fibers, there was carried out chemical analysis of all 3 types of fibers to determine the origin of degradation changes within geometric structure and the mechanical properties of presented basalt fiber types in an alkaline environment of the concrete.…”

Selection of basalt fiber with resistance to concrete alkaline environment

Due to a growing interest in basalt fibers as a reinforcing material for concrete, it becomes necessary to study behavior of such fibers and their interaction with the concrete matrix. Basalt fibers have prospective mechanical and processability properties, as well as good cost-effectiveness when used as concrete reinforcement. However, alkali resistance properties of basalt fiber are rather weak. Three types of basalt fibers from various manufacturers are presented, which were produced from different basalt raw materials and with distinct production technologies. All presented basalt fiber types were studied before mixing with concrete and after it has cured. Size and morphology, young's modulus, tensile strength, bending modulus and flexural properties as well as chemical analysis tests were carried out on the types of basalt fibers under consideration. One type of basalt fibers showed better alkali resistance properties due to the special selection of raw materials for the basalt fibers production.

The study considers the mechanical properties and temperature resistance of partially pyrolysed composites reinforced with various fibres. The composites were prepared by pyrolysis at 650 °C, where only partial conversion of the polymer to the inorganic SiOC structure takes place in the matrix. Such a hybrid matrix bears resemblance to polymeric materials in a density and Young's modulus, but oxidation resistance and creep behaviour are closer to silicate glasses. Pyrolysis also ensures that the whole composite material is non-flammable with very low potential for releasing toxic gases during a fire. Three types of glass fibres (E-glass, R-glass, E-CR-glass fibres), two types of basalt fibres, and two types of high-strength (HS) carbon fibres were used as reinforcements. The mechanical properties-Young's and shear moduli, flexural strength, and fracture toughness-were measured at room temperature. Thermogravimetric measurements and creep tests of these composites allowed estimation of their temperature resistance and fire resistance. The results obtained suggest that the materials under investigation can be applied as panels or shells in the building industry and in transportation facilities.
