“…CF reinforced epoxy composites are characterized by very high stiffness at elevated temperature values, higher than BF or GF [41]. Despite BF and GF's similar chemical structures, epoxy composites produced with a comparable fiber fraction of BF are usually characterized by higher storage modulus values at elevated temperatures [42]. Chinnasamy et al [43] presented the thermomechanical behavior of epoxy glass-aramid composites and showed that synthetic fibers' additions caused an increase in stiffness at elevated temperatures.…”

Aramid (AF), glass (GF), carbon (CF), basalt (BF), and flax (FF) fibers in the form of fabrics were used to produce the composites by hand-lay up method. The use of fabrics of similar grammage for composites’ manufacturing allowed for a comprehensive comparison of the properties of the final products. The most important task was to prepare a complex setup of mechanical and thermomechanical properties, supplemented by fire behavior analysis, and discuss both characteristics in their application range. The mechanical properties were investigated using tensile and flexural tests, as well as impact strength measurement. The investigation was improved by assessing thermomechanical properties under dynamic deformation conditions (dynamic mechanical–thermal analysis (DMTA)). All products were subjected to a fire test carried out using a cone calorimeter (CC).

“…In the last decades, basalt, initially widely used exclusively for aeronautical and defense applications, has been of extraordinary interest in the development of polymeric composites, especially in the form of reinforcing fibers as a valid alternative to conventional glass ones [ 1 ]. Subramanian and Austin [ 2 ] were the first to report the role of interfacial adhesion of pre-functionalized basalt fibers with silane groups in thermosetting polyester matrix composites.…”

Environmentally friendly composite plates intended for load-bearing applications were prepared and systematically characterized in terms of mechanical performances and morphological features. Sample plates combining two extrusion grades of bio-polyamide 11, one of which is plasticized, and two basalt fiber fabrics (plain weave and twill architectures) were obtained by film stacking and hot pressing, and their mechanical properties were investigated by quasi-static flexural and low-velocity impact tests. The comparative analysis of the results, also interpreted by the bending damage analysis, through optical microscope observations, and impact damage analysis through visual inspection and indentation measurements demonstrate that, besides interfacial adhesion issues, the mechanical performance of the laminates need to be optimized through a careful selection of the constituents in the light of the final application. In particular, if the goal is a gain in impact strength, the use of the plasticized matrix is beneficial, but it brings about a loss in stiffness and strength that can be partially compensated by properly selecting a more performing fiber fabric architecture. The latter must also be easily permeated by the matrix to enhance the efficiency of stress transfer from the matrix. Overall, our results can be exploited for the development of bio-composites for particularly demanding applications.

“…The interest in basalt fibre reinforced composites cannot be any longer confined to the academic environment, as confirmed by a recent market report [1] according to which the global basalt fibre market is estimated to grow at a CAGR (Compound Annual Growth Rate) of around 14.2% over the next decade to reach approximately $392.5 million by 2025. Basalt fibre is now well established as a competitor to the more widely used glass fibre as a reinforcement for polymer matrices [2] [3]. Basalt fibres (BFs) feature a natural origin that, if combined with mechanical properties at least comparable with those of traditional E-glass fibres, may at the same time overcome the environmental issues and the typical limitations of vegetal natural fibres, such as flax, hemp, jute, sisal and so forth.…”

In an attempt to improve mechanical properties of basalt fibre/epoxy composites, the present work provides a comparison between the effects of a commercial coupling agent, a thermal de-sizing treatment and a plasma polymerization process on the fibre/matrix interfacial strength. The different basalt fibres were characterized in terms of surface morphology, by FE-SEM observations, and chemical composition, performing FT-IR analysis. The interfacial adhesion has been investigated by single fibre fragmentation test (SFFT) on single fibre composite samples. The plasma polymerization process was able to produce a homogeneous tetravinylsilane (pp-TVS) coating on the surface of basalt fibres, which resulted in a significant increase in the adhesion between basalt fibre and epoxy resin. The surface roughness of the untreated and treated basalt fibres has been measured by Atomic Force Microscopy (AFM) and a relationship between the surface roughness and the adhesion quality between the basalt fibres and the epoxy matrix was found. High-resolution microtomography (µ-CT) has been used to support the analysis of the damage modes during fragmentation tests.
