“…XRD and FTIR were performed to evaluate the surface modification of chemically treated and un-treated basalt fibers, these result shows that maximum pristine layer of basalt fiber with less changes in the surfaces when it is amorphous, but the crystallinity nature of the fiber exhibits more chemical and physical surface changes [5]. The tensile strength and fracture properties of basalt fiber/epoxy composites shows ,that the treated fiber exhibits more deterioration and good bonding on the interphase than the untreated fiber and these modifications are studied with the help of XRD, TEM and FTIR analysis [6,7]. Functional groups and crystalline structure of the fiber responsible for the modification happens in the properties of the composite structure, while seeing flax fiber which has natural crystallinity would produce good mechanical properties [8].…”

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.

“…However, due to the poor adhesive property of BF with EP, the application of basalt fiber-epoxy composite is very limited. The introduction of modified basalt fiber has been considered as one of the most effective methods to improve the performance of EP composites [ 17 , 18 , 19 ]. Nevertheless, in comparison to the wide studies in the state of the art related to the GF, CF and/or natural fibers, the investigation on BF and its based epoxy composites is still very limited in both of fundamental and applied aspects.…”

We aimed to study the impact of surface modification of basalt fiber (BF) on the mechanical properties of basalt fiber-based epoxy composites. Four different types of pretreatment approaches to BF were used; then a silane coupling agent (KH550) was applied to further modify the pretreated BF, prior to the preparation of epoxy resin (EP)/BF composites. The combination of acetone (pre-treatment) and KH550 (formal surface treatment) for basalt fiber (BT-AT) imparted the EP/BF composite with the best performance in both tensile and impact strengths. Subsequently, such modified BF was introduced into the flame-retardant epoxy composites (EP/AP750) to prepare basalt fiber reinforced flame-retardant epoxy composite (EP/AP750/BF-AT). The fire behaviors of the composites were evaluated by vertical burning test (UL-94), limiting oxygen index (LOI) test and cone calorimetry. In comparison to the flame-retardant properties of EP/AP750, the incorporation of BF-AT slightly reduced LOI value from 26.3% to 25.1%, maintained the good performance in vertical burning test, but increased the peak of the heat release rate. Besides, the thermal properties and mechanical properties of the composites were investigated by thermogravimetric analysis (TGA), universal tensile test, impact test and dynamic mechanical analysis (DMA).

“…Recently, many efforts have been made to improve the durability of BFRP in seawater. Among these, adding nanomaterials, e.g., silanized montmorillonite (Si–MMT) [ 17 ], nanotubes (HNTs) [ 18 ], etc., to the polymer matrix is one option that can improve the interface interaction between the BF and the polymer matrix, thereby increasing the bonding strength between the enhanced interface [ 19 ]. These studies were mostly focused on BFRP composite materials, however, and the performance of BF is also critical especially after the destruction or degradation of BFRP.…”

Effect of Seawater Environment on the Structure and Performance of Basalt Continuous Fiber

2021

Basalt continuous fibers (BFs) have been widely applied in the construction industry including marine applications, however, the corrosion mechanism of BFs in a seawater environment is still not well understood. In this work, we explored the effect of the seawater environment on the weight loss, tensile strength, surface morphology, and microstructure structure of BFs via soaking the BFs in seawater solutions at different temperatures and durations. Results show that the weight loss ratio of BFs decreases at the first stage (around 18 h) of soaking at 80 °C, 85 °C, and 90 °C and then increases for longer soaking durations, while the tensile strength has the opposite change. This enhancement of tensile strength and chemical resistance (at the first stage of seawater soaking) is dominated by the ion-exchange induced ‘blunting’ mechanism, even though the results from a Fourier transform infrared (FT-IR) spectrometer and energy-dispersive spectroscopy (EDS) revealed the damaging of the Si–O–Si tetrahedral structure during the corrosion process. This work revealed the full corrosion process and corresponding mechanism of BFs in a seawater environment.
