This experiment is to investigate delamination damage of carbon/basalt/epoxy hybrid composites on the drilling manufacturing process. The damage is caused by drilling on wet and dry conditions with a twist drill size of 8 [mm], and 10 [mm] have been conducted. This experiment was carried out based on the ASTMD 5470-12 standard. Three hybrid composites have been manufactured for samples such as H1, H2, and H3. Additionally, the carbon fibers reinforced epoxy composites (CFRP) and basalt fibers reinforced epoxy composites (BFRP) as experiment control had built. The aim is to assess the defect zone of carbon/basalt hybrid composite against the drilling. The examination results showed that the feed rate speed of various laminate configurations e.g., H1, H2, and H3, on drilling dried between twist drill of 10 [mm] and 8 [mm] diameters are 50.5 %, 25 %, and 33.2 %, respectively. Also, adding lubricant during the drilling work has reduced peel-out and push-out effectively. The delamination defect has been the high resulted in drilling using drill 10 [mm] in wet or dry conditions. In contrast, delamination defect has occurred minimum on drilling hole using twist drill 8mm in work wet and dry condition. It has still occurred. From this research, the combination sequence of basalt and carbon fiber has the possibility to experience the delaminate damage in dry drilling processes.

In this study, the flexural and impact properties of hybrid composites including the thin-ply unidirectional (UD) carbon fibers and basalt fabrics with different stacking sequences were investigated. Hybrid composites were fabricated by 2 layers of thin-ply UD carbon fibers and 6 layers of basalt fabrics in which the position of thin-ply UD carbon fibers was changed from the center to the outermost layers for different samples. Results indicated that by embedding the thin-ply UD carbon fibers in the laminates, both flexural and impact properties of the samples were considerably improved. The highest flexural strength (451 MPa) and modulus (37 GPa) values were achieved when the thin-ply UD carbon fibers were placed at the outermost layers; these values were respectively 24% and 44% higher than those of the sample without these fibers. However, results indicated that by placing the thin-ply UD carbon fibers at the center of samples, the failure behavior of samples was changed from catastrophic failure to progressive; and a pseudo-ductile behavior was observed in the mentioned samples. The highest pseudo-ductile strain value of 0.0054 was obtained by placing the thin-ply UD carbon fibers at the center of samples. Similar to the trend pseudo-ductility of samples, the flexural strain of samples improved by nearing the thin-ply UD carbon fibers to the center of samples. Similar to the flexural strain of samples, the results of Charpy impact tests indicated that by nearing the thin-ply UD carbon fibers to the outermost layers, the absorbed energy values decreased.

Structural Applications

New technologies in the automotive industry require lightweight, environment-friendly, and mechanically strong materials. Bast fibers such as kenaf, flax, and hemp reinforced polymers are frequently used composites in semi-structural applications in industry. However, the low mechanical properties of bast fibers limit the applications of these composites in structural applications. The work presented here aims to enhance the mechanical property profile of bast fiber reinforced acrylic-based polyester resin composites by hybridization with basalt fibers. The hybridization was studied in three resin forms, solution, dispersion, and a mixture of solution and dispersion resin forms. The composites were prepared by established processing methods such as carding, resin impregnation, and compression molding. The composites were characterized for their mechanical (tensile, flexural, and Charpy impact strength), thermal, and morphological properties. The mechanical performance of hybrid bast/basalt fiber composites was significantly improved compared to their respective bast fiber composites. For hybrid composites, the specific flexural modulus and strength were on an average about 21 and 19% higher, specific tensile modulus and strength about 31 and 16% higher, respectively, and the specific impact energy was 13% higher than bast fiber reinforced composites. The statistical significance of the results was analyzed using one-way analysis of variance.

In order to improve the mechanical properties of basalt fiber/epoxy composites, carboxylic CNTs were filled into the epoxy matrix of basalt fiber/epoxy composites. Firstly, the carboxylic CNTs filled epoxy composites with different carboxylic CNTs content were studied. Quasi-static and dynamic compression results show that when the content of carboxylic CNTs increased from 0wt% to 1wt%, both ultimate quasi-static and dynamic compressive strength of CNTs filled epoxy composites showed increasing tendencies. However when the content of carboxylic CNTs increased from 1 wt% to 1.5 wt% both ultimate quasi-static and dynamic compressive had decreasing tendencies. Base on above results, carboxylic CNTs (1wt%) filled basalt fiber/epoxy composites were fabricated by mould pressing method. Quasi-static and dynamic compression results showed that both ultimate quasi-static and ultimate dynamic compressive strength of carboxylic CNTs filled basalt fiber/epoxy composite were enhanced compared with those of basalt fiber/epoxy composites without CNTs. However, the critical failure strain were all lower than those of basalt fiber/epoxy composites without CNTs. Failure mechanism analysis showed that the carboxylic CNTs was beneficial for forming good interfacial bonding between epoxy matrix and basalt fibers, and the advantage of high axial tensile strength of basalt fibers could be fully utilized, which is responsible for the enhanced ultimate compressive strength of carboxylic CNTs filled basalt fiber/epoxy composites.

Basalt fiber (BF) is an environmentally friendly material which can reduce environmental problem. In this study, CF/BF composite materials that can reduce the volume of carbon fiber (CF) by hybridizing BF and CF were studied. BF was specially laminated on the surface of CF so that the CF does not come into contact with the external environment. Basalt fibers were designed based on the arrangement angles and volume fraction. Evaluation by tensile, bending and intermittent shear tests, showed that the volume fraction of BF was more influential than the arrangement angles. When the volume fraction of BF was approximately 27%, high mechanical properties were obtained at all arrangement angles used in this experiment.

Mechanical Behaviors

This study focuses on tensile and flexural behaviors of epoxy composites, which have been reinforced by oxidized polyacrylonitrile fibers and high-performance fibers (carbon, glass, and Kevlar). In hybrid composites, the parameters of hybridization show positive or negative hybrid effects on its mechanical properties. The results of energy absorption achieved from the tensile test depicted that reinforced hybrid composites by two plies of oxidized polyacrylonitrile fiber and two plies of carbon, Kevlar, and glass fibers with energy absorption of 916, 700, and 899 kJ m–3 had the maximum hybridization parameter, which were 1.1, 0.64, and 1.54, respectively. Also, the mentioned hybrid composites with flexural stresses of 279.4, 198.5, and 167.3 MPa had the maximum hybridization parameter in a flexural test, which were 3.01, 2.68, and 1.80, respectively. Hybrid composites, which were reinforced by three plies of oxidized polyacrylonitrile fiber/one ply carbon fibers, three plies of oxidized polyacrylonitrile fiber/one ply of glass fibers, and two plies of oxidized polyacrylonitrile fiber/two plies of Kevlar fibers, had the maximum pseudo strain in their group, which were 0.12%, 0.65%, and 0.17%, respectively. The microstructure investigations depicted crossing cracks among oxidized polyacrylonitrile fiber and cutting the oxidized polyacrylonitrile fiber, which were caused to increase the hybridization parameters in mechanical tests. Also, it was found that as compared with carbon, glass, and Kevlar fibers, oxidized polyacrylonitrile fiber had a ductile fracture, which was the reason for the pseudo-ductility behavior in hybrid composites.

High-performance composites based on basalt fibers are becoming increasingly available. However, in comparison to traditional composites containing glass or carbon fibers, their mechanical properties are currently less well known. In particular, this is the case for laminates consisting of unidirectional plies of continuous basalt fibers in an epoxy polymer matrix. Here, we report a full quasi-static characterization of the properties of such a material. To this end, we investigate tension, compression, and shear specimens, cut from quality autoclave-cured basalt composites. Our findings indicate that, in terms of strength and stiffness, unidirectional basalt fiber composites are comparable to, or better than epoxy composites made from E-glass fibers. At the same time, basalt fiber composites combine low manufacturing costs with good recycling properties and are therefore well suited to a number of engineering applications.

Promising lightweight composite materials, bridging the gap between Polymer and Ceramic Matrix Composites, are manufactured as polymer derived ceramics by the use of polysiloxanes and basalt fibers. Such competitive free formable Hybrid Composites are supposed to be capable for lightweight applications in a temperature range between 300 °C and 850 °C and short time exposure up to over 1000 °C, even in oxidative atmosphere. Cheap raw materials like basalt fibers and siloxane resins in combination with performing manufacturing technologies can establish completely new markets for intermediate temperature composites. These attributes enable the Hybrid Composites as ideal material for fire retardant applications in automotive engineering and public transportation, as well as in fire protection systems in electrical and civil engineering applications. In this study, the most prominent fields of application and engineering solutions for Hybrid-CMC are reviewed and the results of the thermal resistivity analysis effectuated on basalt fiber reinforced SiOC samples are presented. This study consisted of several air exposures between 1 h and 50 h and temperatures in the range of 650 °C to 1100 °C. Remaining mechanical resistance was characterized by Impulse Excitation Technique (IET) and Interlaminar Shear Strength (ILSS) tests. Basalt fiber reinforced samples exhibited a decent level of mechanical performance even after the most demanding exposures. Due to the poor oxidation resistance of carbon fibers, Cf/SiOC composites were completely degraded after long-term exposure at 500 °C in air.

The main aim of this study was to investigate the effect of basalt fiber (BF) reinforcement in wood–plastic composites (WPCs). Basalt/wood hybrid composites based on polypropylene (PP) were prepared with different percentages of the reinforcement (the total fiber content was 10 wt%, 15 wt%, and 20 wt%). The BCS17-6.4-KV16 chopped basalt fibers with nominal diameter of 17 μm, cutting length of 6.4 mm, and wood fibers—Lignocel C 120 with the particle size of 70–150 µm—were used as a reinforcement. Composites were produced by the injection molding method. The density of the produced composites and their processing properties such as Vicat softening point and shrinkage were determined. In addition, the thermal expansion behavior of filled plastic composites was investigated. Mechanical tests were subsequently performed to evaluate the tensile, flexural, and impact properties at various temperatures (i.e., at −24 °C, 23 °C, and 80 °C) and after soaking in water. Scanning electron microscopy images were acquired to assess the effects of reinforcement and homogenization of mixtures and to determine the characteristics of the microstructure. The results showed that the hybridization process improved the tensile and flexural properties of reinforced wood composites. Moreover, the incorporation of high-strength basalt fibers into the composite led to increased stiffness. Even a small addition of 10 wt% total fibers led to a significant decrease in shrinkage and coefficient of thermal expansion.
