“…Unmodified PLA polymer was used as a reference sample. The composition of the composites was determined based on previous studies, and by reviewing the literature where it is shown that a high amount of fillers hinders the preparation process and the introduction of BF into the polymer matrix at an amount of > 20 wt% does not cause a significant reinforcement [18]. WF and BF were compounded with PLA using a co-rotating twin-screw extruder 1 3…”

In this study, biodegradable biocomposites based on polylactide with basalt fibres (BFs) or wood fibres (WFs) of 7.5 or 15 wt% were prepared by injection moulding. Various tests, including tensile test, bending test and impact test, were carried out to investigate the mechanical properties of the composites. Additionally, the samples were tested at different temperatures. Depending on the type of fibre, differences were noted in their mechanical properties; the addition of WF caused a decrease in strength and the higher the fibre content, the higher the decrease was noted from 18% up 25% in the case of tensile strength. However, the Young modulus was improved by 45% for composites with 15 wt% of WF. The addition of BF improved all the properties, especially Young modulus was improved by over 45%. Despite the low strength observed in neat polylactide at high temperatures-394 MPa, the addition of WF or BF improved the flexural strength more than twofold up to 1684 MPa (PLA/15BF). Moreover, the addition of natural fibres caused an increase in dimensional stability as shown by the decrease of the coefficient of thermal expansion which dropped over 50% for composites with 15 wt% of BF, which significantly expands the areas of use of materials. After 4 weeks of biodegradation, only a slight decrease approximately 5% was observed in the mechanical properties together with an increase in crystallinity. Overall, the results confirm that the prepared composites can be successfully used in engineering applications with long-term operation.

“…Epoxy/basalt fiber composites can integrate the advantages of the two materials and are expected to own excellent properties . Unfortunately, since basalt fibers are composed of inorganic oxides which have weak interfacial bonding with the organic epoxy matrix, the combination and cooperation between the two materials are poor .…”

Epoxy/basalt fiber composites were modified by 2D montmorillonite (MMT), 0D nanoSiO2, or 2D MMT/ 0D nanoSiO2 double nanoparticles. Mechanical tests showed that all the modified composites had considerably improved interlaminar shear strength and notch impact strength compared with the unmodified epoxy/basalt fiber composites, and that the double nanoparticle‐modified composites displayed the greatest improvement. X‐ray diffraction, transmission electron microscopy, and scanning electron microscopy revealed that co‐addition of 2D MMT and 0D nanoSiO2 into epoxy/basalt fiber composites produced a unique microstructure. The MMT was completely exfoliated into nanoscale mono‐sheets and interacted with nanoSiO2 particles to assemble into networks. The networks trapped many epoxy molecules within them and they tightly surrounded basalt fibers to form buffer layers. These results indicate that double nanoparticles of different dimensionality promote epoxy molecules to infiltrate between, combine with and coat basalt fibers more effectively than single nanoparticles, which facilitates better cooperation of epoxy and basalt fibers in resisting external forces. Modification with dimensionally different nanoparticles is an effective pathway to improve the performance of epoxy/basalt fiber composites and broaden their application fields. POLYM. ENG.

“…Basalt powder contains so many minerals in that the structure of the minerals were important, if there is any changes in the structure of minerals which in term affect the property of the powder these changes are easily identified with the XRD and FTIR analysis [1]. Powder formed basalt shows an improved property when mixed with the raw natural fiber in terms of tensile, flexural strength and dynamic mechanical performance and morphological investigations [2]. FTIR and x-ray diffraction helps to study about the various patterns of organic structure and mineral composition of the composite, the presence of rich calorified minerals in the natural fibers will produce good strength blended with basalt powder [3].…”

The objective of this research is to examine the low velocity impact (LVI) and effect of compression after impact (CAI) properties on flax fiber and basalt powder reinforced polyester composites. For this study the 10 layers of flax fiber, basalt powder by varying from 5% to 30% the composites were prepared. In the LVI analysis composite (10 layers of basalt/10% of basalt powder) shows better results about 1755 N of force and for CAI also same composite B experienced with less deformation and more residual energy to absorbing the force of about 2250 N. The addition of filler material up to certain limit will support the reinforcing fiber to achieve some enhanced property. The morphological changes and their properties were assessed using Fourier Transform Infrared Spectroscopy (FTIR) and x-ray diffraction Analysis (XRD) studies for particulate basalt powder. The presence of Pyroxene group of rocks in basalt powder responsible for stability in high temperatures seen using XRD analysis. The band width around 3390-3425 cm −1 shows the presence of hydroxyl group (OH) in the basalt powder. This proved that the materials are Polar Hydrophilic in nature examined with FTIR spectroscopy.
