“…Aminanda, et al [22] studied Nomex honeycomb and aluminum honeycomb, and found that Nomex honeycomb panels have more stable platform stress and better energy absorption performance than aluminum honeycomb panels; Amélie, et al [23] carried out experimental research on the sandwich structure subjected to medium-speed impact (120 m/s) as aviation armor, and found that Nomex honeycomb panels have lighter weight and higher impact resistance. In the civil industry, such as the Internet, 5G communication, radar antenna, and other military fields, the interference of the metal sandwich structure in electrical performance has seriously affected the development of the industry [24]. Table 1 shows the dielectric constant and dielectric loss of some high-tech fibers [25][26][27].…”

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 altered composition of the fiber increased the electrostatic interactions. The aggregation of basalt fiber was obvious during processing, providing a weak enhancement effect on the epoxy resin [ 26 ]. As shown in Figure 1 c, the surface of basalt fiber was relatively rough, indicating that the sodium hydroxide had etched the surface of the fiber.…”

Basalt Fiber-Based Flame Retardant Epoxy Composites: Preparation, Thermal Properties, and Flame Retardancy

et al. 2021

We aimed to study the impact of surface modification of basalt fiber (BF) on the mechanical properties of basalt fiber-based epoxy composites. Four different types of pretreatment approaches to BF were used; then a silane coupling agent (KH550) was applied to further modify the pretreated BF, prior to the preparation of epoxy resin (EP)/BF composites. The combination of acetone (pre-treatment) and KH550 (formal surface treatment) for basalt fiber (BT-AT) imparted the EP/BF composite with the best performance in both tensile and impact strengths. Subsequently, such modified BF was introduced into the flame-retardant epoxy composites (EP/AP750) to prepare basalt fiber reinforced flame-retardant epoxy composite (EP/AP750/BF-AT). The fire behaviors of the composites were evaluated by vertical burning test (UL-94), limiting oxygen index (LOI) test and cone calorimetry. In comparison to the flame-retardant properties of EP/AP750, the incorporation of BF-AT slightly reduced LOI value from 26.3% to 25.1%, maintained the good performance in vertical burning test, but increased the peak of the heat release rate. Besides, the thermal properties and mechanical properties of the composites were investigated by thermogravimetric analysis (TGA), universal tensile test, impact test and dynamic mechanical analysis (DMA).

“…Film-holding experiments showed that the CTAC-modified BF had the highest film-holding rate, film-holding volume, and film-holding strength. Zhu et al [56,57] from Xi'an Jiaotong University prepared composites with la-ethylenediaminetetraacetic acid (EDTA)-coated treated p-BFs and bisphenol A dicyanate (BADCy) for mechanical testing. The results showed that the initial decomposition temperature of the modified composite was 145 • C higher than that before treatment.…”

Basalt fiber (BF) has a high mechanical strength, excellent temperature resistance, good chemical stability, low energy consumption, and an environmentally friendly production process. In addition, BF-reinforced polymers (BFRPs) have good corrosion resistance and designability; thus, they meet the application requirements of electrical equipment, such as new conductors, insulating pull rods, and composite cross-arms. However, there are still a series of technical issues in the mass production of BF, and the stability of the products needs to be further improved. Therefore, the research on the production, modification, and application of BF is necessary. This paper discusses the chemical composition and production technology of BF, describes the morphology and properties of BF, summarizes the interface problems and modification methods of composites, and finally, introduces the application prospects of BF in the field of electrical materials, which is expected to provide a reference for the application and promotion of BFRP in the future.
