“…The representative fibers are glass fiber, carbon fiber, aramid fiber, and basalt fiber; the honeycomb materials include aramid honeycomb, aluminum honeycomb, and so on. With the increasing demand for lightweight and performance-based materials in the structural field, new composite materials such as foam, fiber, and honeycomb have been used more and more widely [7,8]. The representative fibers are glass fiber, carbon fiber, aramid fiber, and basalt fiber; the honeycomb materials include aramid honeycomb, aluminum honeycomb, and so on.…”

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.

“…Basalt fibers (BF) are a new type of inorganic fiber produced by melting basalt at high temperatures (approximately 1200 °C to 1500 °C) [ 14 , 15 ]. They have excellent resistance to high temperatures [ 15 ]. Below 200 °C, the average tensile strength of BF is hardly affected [ 16 ].…”

“…Furthermore, they are relatively inexpensive and ecologically safe due to their manufacturing process, which does not require a substantial amount of energy and chemical additives to obtain an appropriate thermal strength and crystal structure [ 18 ]. Owing to the contents of SiO 2 , Al 2 O 3 , MgO, CaO and TiO 2 in basalt, BF have good chemical stability, chemical resistance, corrosion resistance and water resistance [ 15 , 19 ]. Other advantages, such as a high Young’s modulus, uniform dispersion and good compatibility with cement-based materials, have also been widely recognized [ 14 , 20 ].…”

This study investigated fundamental mechanical properties of a basalt fiber reinforced engineered cementitious composite (BF-ECC) with different volume fractions of basalt fiber (BF), water–binder ratio (W/B) and fly ash (FA) content. The compressive strength, splitting tensile strength, flexural strength and static modulus of BF-ECC were studied at 3, 28 and 56 days, respectively, to explore their development along the ages. Furthermore, the scanning electron microscopy (SEM) analysis was conducted to evaluate the microstructure of BF-ECC. Experiment results demonstrated that bond quality between the BF and the matrix is good, which leads to a significant increase in the flexural strength and splitting tensile strength. The pozzolanic effect of FA obviously improved the splitting tensile and flexural strength of BF-ECC after 56 days of curing, and the appropriate content of the FA content in the BF-ECC ranges from 50% to 60%.

“…Já as fibras de basalto, produzidas a partir do derretimento da rocha vulcânica, tem ganhado espaço nos últimos anos sobretudo pelas boas propriedades de resistência, rigidez, durabilidade, resistência à ácidos e solventes e baixa absorção de água. Além disso, o processo de fabricação é mais barato que o das fibras de vidro e de carbono [7]. Em relação às propriedades mecânicas, as fibras de basalto possuem desempenho superior às fibras de vidro e inferior em relação às fibras de carbono [8].…”

As barras de aço comumente utilizadas na construção civil são suscetíveis à corrosão, sobretudo quando sujeitas à ambientes agressivos. Materiais constituídos por polímeros podem ser uma alternativa viável para substituição do aço nesses casos. Compósitos em fibra de basalto são um material relativamente novo e sua aplicação estrutural está iniciando no Brasil na forma de barras. Com intutito de conhecer melhor o comportamento desse material foram moldadas quatro vigas, duas reforçadas com barras de aço e duas com barras em fibra de basalto. As vigas foram submetidas à ensaios de flexão onde puderam ser observados os modos de ruptura e as relações carga-deflexão. Devido à limitações dos ensaios o esforço de cisalhamento foi preponderante na ruptura das vigas. As vigas dos dois materiais apresentaram uma carga última muito próxima e maiores deflexões foram verificadas na viga reforçada com fibra de basalto.
