“…The value of E f for both the basalt fabric and basalt/unidirectional fabric was measured to be equal to 85 GPa, as it is also reported in ref. , whereas the value of E f for the glass fabric was estimated to be equal to 70 GPa. In addition, another well‐known equation was employed as follows:

\begin{matrix} lefttrue \\ {normalE}_{normalc} = {normalV}_{normalm} {normalE}_{normalm} + η {normalV}_{normalf} {normalE}_{normalf} \end{matrix}

where η the Krenchel factor, denoting the orientational character of the fibers.…”

In the present study the effectiveness of two different biodegradable polymers, namely Polylactic acid (PLA) and ECOVIO (EC), a blend of a copolyester and PLA, as matrix materials for basalt fiber composites, prepared with the "film stacking method" has been investigated. Comparison with composites based on glass fiber mat has also been performed. The addition of basalt fibers, leads to a significant improvement in tensile and flexural strength and stiffness. The ECOVIO/basalt fiber composites exhibited the highest percentage enhancement, while the failure strain decreased dramatically. Therefore, the basalt fabrics appear to have a competitive mechanical performance with the glass fiber mats employed.

Fibres have been used in construction materials for a very long time. Through previous research and investigations, the use of natural and synthetic fibres have shown promising results, as their presence has demonstrated significant benefits in terms of the overall physical and mechanical properties of the composite material. When comparing fibre reinforcement to traditional reinforcement, the ratio of fibre required is significantly less, making fibre reinforcement both energy and economically efficient. More recently, waste fibres have been studied for their potential as reinforcement in construction materials. The build-up of waste materials all around the world is a known issue, as landfill space is limited, and the incineration process requires considerable energy and produces unwanted emissions. The utilisation of waste fibres in construction materials can alleviate these issues and promote environmentally friendly and sustainable solutions that work in the industry. This study reviews the types, properties, and applications of different fibres used in a wide range of materials in the construction industry, including concrete, asphalt concrete, soil, earth materials, blocks and bricks, composites, and other applications.

“…Obtained results determine that all fillers linearly increase the elastic modulus of the PLA matrix ( fig. 11), and this effect is associated to the higher moduli of the fillers compared to the hosting matrix (85 GPa [33], 170 GPa [34] and 10.6 GPa [35] for basalt, talc and sepiolite, respectively). Despite the higher elastic modulus of talc platelet compared to basalt fibers, the shape and the orientation of the basalt fibers induce an higher stiffening effect in the PLA matrix, with a maximum increase of elastic modulus of about 121%.…”

In this work, basalt microfiber reinforced poly(lactic acid) (PLA) composites filled with talc nanoplatelets (2D) and sepiolite nanofibers (1D) were prepared at different compositions and tested to assess the effects of filler geometry. Thermal analysis results show that crystallinity of amorphous PLA can be enhanced up to 24% by adding basalt and talc. Thermal stability of PLA is increased by basalt microfibers whereas talc and sepiolite prompted early degradation in binary composites. In ternary systems, i.e. PLA/basalt/talc and PLA/basalt/sepiolite, thermal stability was further increased. Mechanical tensile and flexural properties were remarkably increased for a specific composition basalt (30 wt%) and talc (10 wt%) with a final enhancement of 176% and 261% for modulus and 46% and 43% for strength respectively in tensile and bending configuration. For the composition, the coefficient of thermal expansion is significantly reduced up to 54% of the corresponding pristine PLA value. The increase of thermal conductivity is mainly related to the presence of 1D sepiolite, with a variation of ~54% for the 10 wt% PLA/sepiolite binary system. Finally, a significant increment of impact property was observed by unnotched Charpy impact tests for talc (+97%) and basalt (+140%) composites.
