“…Moreover, basalt is biologically inert, and the weathering of basalt rocks increase the mineral content of soil which further strengthens its natural character. Basalt fibres are typically produced by two different technologies: Junkers method and spinneret technology [19]. The shorter basalt fibres are prepared by the Junkers method and the continuous fibres are prepared by the spinneret technology [20].…”

Abstract. This paper focuses on the reinforcing of Poly(lactic acid) with chopped basalt fibres by using silane treated and untreated basalt fibres. Composite materials with 5-10-15-20-30-40 wt% basalt fibre contents were prepared from silane sized basalt fibres using extrusion, and injection moulding, while composites with 5-10-15 wt% basalt fibre contents were also prepared by using untreated basalt fibres as control. The properties of the injection moulded composites were extensively examined by using quasi-static (tensile, three-point bending) and dynamic mechanical tests (notched and unnotched Charpy impact tests), dynamic mechanical analysis (DMA), differential scanning calorimetry (DSC), heat deflection temperature (HDT) analysis, dimensional stability test, as well as melt flow index (MFI) analysis and scanning electron microscopic (SEM) observations. It was found that silane treated chopped basalt fibres are much more effective in reinforcing Poly(lactic acid) than natural fibres; although basalt fibres are not biodegradable but they are still considered as natural (can be found in nature in the form of volcanic rocks) and biologically inert. It is demonstrated in this paper that by using basalt fibre reinforcement, a renewable and natural resource based composite can be produced by injection moulding with excellent mechanical properties suitable even for engineering applications. Finally it was shown that by using adequate drying of the materials, composites with higher mechanical properties can be achieved compared to literature data.

“…It is generally known that the strength of a glass is mainly governed by the size of defects present in the material [5] (i.e., weakest link statistics), resulting in higher strength for fibers than for bulk glass and an increasing trend for the tensile strength of fibers with decreasing fiber diameter [5][6][7]. Although tensile testing methods are most often applied to continuous fibers, the mechanical behavior of shorter, cylindrically-shaped fibers (e.g., discontinuous chopped or wool fibers) can also be quantified [8]. The tensile strength of continuous and discontinuous glass fibers is affected by parameters such as the chemical composition, 0022-3093/$ -see front matter Ó 2008 Elsevier B.V.

“…Note that Mg 2+ and Ca 2+ can associate with the chemical bonds ‐Si‐O‐Si‐ and ‐Si‐O‐AL‐ in the network. These components do not participate in forming the primary network structure and can be considered to be network modifiers . Table summarizes the aforementioned analysis of the functions and effects of different chemical components on the stability of the network structure of basalt fibers.…”

“…The tensile strength of BFRP composites is determined by three major factors, the manufacturing technology, matrix compatibility and fiber strength . The factors of the manufacturing technology and matrix comparability primarily affect the uniform loading carrying ability of the individual fibers in the composite.…”

This article studies the correlation between the tensile strength and the chemical composition of basalt fiber roving and analyzes rovings with different chemical compositions to derive equations that predict the roving strength. The tensile properties of different types of basalt fiber roving that were impregnated with two types of resins were first tested, while the chemical compositions of the basalt fibers were analyzed. The functional roles played by different chemical constituents and their contributions to the tensile strength were analyzed and used to verify the correlation between the strength and the effective composition. A numerical method was used to derive equations to predict the strength of the basalt fibers. The results show that the tensile strengths of the impregnated basalt fiber roving vary from 2313 to 2714 MPa, depending on the manufacturers, and were 7–25% higher than that of E‐glass fiber roving. The chemical constituents of the basalt fibers play four different functional roles, network formers, network intermediates, network changers and network modifiers. Chemical composition groups are subsequently identified that have positive, negative and uncertain effects on the tensile strength. The weighting factors of the chemical composition are regressed, resulting in predictions for the tensile strength that are in good agreement with experimental measurements. The results from this study can be used to predict the strength of basalt fibers in basalt mineral analysis. POLYM. COMPOS., 40:2959–2966, 2019. © 2018 Society of Plastics Engineers
