Abstract The objective of the research was to determine if basalt fiber reinforced polymer composites are feasible, practical, and a beneficial material alternative for transportation applications. No significant differences in stiffness and strength were found between basalt fabric reinforced polymer composites and glass composites reinforced by a fabric of similar weave pattern. Aging results indicate that the interfacial region in basalt composites may be more vulnerable to environmental damage than in glass composites. However, the basalt/epoxy interface may also be more durable than the glass/epoxy interface in tension- tension fatigue because the fatigue life of basalt composites is longer. A wide disagreement between the literature properties of basalt fibers and the properties measured in this study renders any further consideration of basalt reinforced composites highly problematical. Composites manufacturing issues with basalt fabric were also investigated. The measurement results of the in-plane permeability for basalt twill 3×1 fabric material showed that a high correlation exists between the two principal permeability values for this fabric. This is in contrast to the lack of correlation found in other weave patterns, and may point to an important material selection criteria for mass production of composites by liquid molding. 17.

Liberec 2016 Abstract: With the advancement and continuing integration of composite materials and technology in today's modern industries, research in this field is becoming more and more significant. Basalt fibers are very promising materials due to their fire resistance related to magmatic origin, superior mechanical properties and relatively low cost. On the other hand, being a relatively new kind of fiber, they are still not studied extensively. There are very few indications in technical papers about their behavior after aging treatments. The current study investigates the possibility of using basalt with other types of yarns and consequently the effect of hybrid woven structure on load bearing capacity and durability. This thesis conveys a better insight into characteristics of Basalt fibers specifically, alongside commonly used fibers to design and develop hybrid woven fabrics for Textile Reinforced Concrete (TRC) materials.

Abstract Sandwich fiber metal laminates (FMLs) grabs significant growing attention among disparate engineering industries such as defense, aerospace and commercial vehicle manufacturers, due to its improved mechanical, thermal and electrical properties. Over the past few decades, FMLs were used as an impeccable identical for classical fiber composites like carbon and E-Glass. This prospective work interrogates mechanical behaviour of Basalt/Kevlar/AA 8090 reinforced FML fabricated by hand layup - compression moulding process. The low-velocity impact, flexural and tensile behavior of fabricated FMLs were calculated by various mechanical testings done as per ASTM standards. Fractured surface of the FML also analyzed by scanning electron microscopic images for understanding the fracture behavior of the proposed outcome.

    Article Mechanical Properties of a Unidirectional Basalt-Fiber/Epoxy Composite David Plappert 1,* , Georg C. Ganzenmüller 1 , Michael May 2 and Samuel Beisel 1 1 Institute for Sustainable Systems Engineering, Albert-Ludwigs Universität Freiburg, 79100 Freiburg i. Br., Germany; [email protected] (G.C.G.); [email protected] (S.B.) 2 Fraunhofer Ernst-Mach-Institute for High-Speed Dynamics, EMI, 79100 Freiburg i. Br., Germany; [email protected] * Correspondence: [email protected] Received: 23 June 2020; Accepted: 27 July 2020; Published: 29 July 2020 Abstract: 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. Keywords: basalt fibers; natural fibers; polymer-matrix composites (PMCs); mechanical properties; mechanical testing 1. Introduction Modern basalt fibers are a suitable high performance reinforcement for polymer composites. The mechanical properties of unidirectional basalt fiber reinforced polymers (BFRP) are similar to, or better than E-glass fiber reinforced polymers (GFRP)—elongation and stress at break are comparable [1] while their Young’s Modulus is higher by up to 35% [2].
