“…In FEMD/BF composites, HCl first entered (Supporting Information, Figure S3) and catalyzed further reaction of furan, thereby elevating the crosslinking density and strength retention of FEMD. Extending the time of soaking in HCl may decompose FEMD and damage basalt fiber, which both significantly decreased the strength of FEMD/BF composite. On the other hand, with increasing soaking time (more than 45 h) in HCl, the strength retentions of all composites decreased, which became obvious at a higher epoxy content.…”

A furan/epoxy blend applicable to composite manufacture was studied and corresponding basalt fiber-reinforced composites were prepared. The processability, mechanical properties, and reasons for the improved mechanical properties of this blend were investigated by rheology machine, mechanical testing machine, and scanning electron microscopy. With excellent processability, furan/epoxy was suitable for manufacturing composites. Furan/epoxy with the ratio of 5/5 showed the best properties, and the impact strength, flexural strength and flexural modulus were 15.43 kJ/m 2 , 102.81 MPa, and 3209.40 MPa, respectively. The river-like fracture surface of the furan/epoxy system was well consistent with the mechanical properties. The mechanical and anti-corrosive properties of basalt fiber-reinforced furan/epoxy composites were also studied. The mechanical properties of composites changed the same as those of furan/epoxy matrix did. Furan resin effectively improved the anti-acid but not anti-alkali property of composites, probably because furan could be cured in acidic condition and basalt fiber was resistant to acid and alkali.

“…Only a limited number of studies have been conducted on basalt FRP composites. These reports conclude that the alkaline resistance of basalt fibers is superior to that of glass fibers, whereas the acid resistance is poorer [7,8] . An investigation of special alkaline-proof basalt fibers showed that their alkaline resistance was superior to their acid resistance, especially in terms of the effect on the flexural modulus [9] .…”

This paper investigates the degradation of basalt fiber reinforced polymer (BFRP) bars used for concrete construction in an alkaline environment. The relationships between tensile strength, elastic modulus, shear strength and moisture absorption rate over time are analyzed using a tension test, short-beam test and moisture absorption weighting. The tensile strength degradation of BFRP bars was further compared with that of Glass FRP (GFRP) bars in the literature. The results indicated that BFRP bars exhibit relatively good resistance to alkaline corrosion, maintaining more than 60% of their original strength after 9 weeks at 55 ° C in an alkaline solution. The moisture absorption of BFRP bars conforms to Fick ' s law, which shows that the degradation mechanism is controlled by matrix and related interface degradation. This finding is supported by comparison with the shear strength degradation trend. Compared to GFRP bars under similar alkaline conditions, BFRP bars exhibit a similar degradation rate during the initial phase, but maintain higher tensile strength and strength retention over time.

“…These properties increased with increased aging, but the mechanical properties of samples aged by water, acid and environmental weathering displayed a decrease in their properties. In another study, the resistance of basalt fibers in alkaline solution was noticed to be better than that of glass fibers while the acid resistance was found to be poorer [18,19].…”

This chapter describes an experimental investigation into the dynamic mechanical properties of coir and coconut husk particulate reinforced polymer composites which were prepared by the hot press method. The composite was immersed in a strongly acidic environment of pH 2.2 for a period of 14 and 28 days (14P and 28P). Values of storage modulus at different vibrational frequencies recorded for the polymers at low temperatures where the molecules are still tightly compressed and the region of first solid state transitions are:
