The superior advancement of composite materials has necessitated the development of different types of fibers that can provide outstanding characteristics at a reasonable cost. A new generation of FRP composites released in the previous decade is Basalt Fiber Reinforced Polymer (BFRP). This research studies the physical and mechanical properties of BFRP bars compared with Glass FRP (GFRP) bars. Variables investigated in this study were the types of fibers (basalt and glass), bar diameter (10 mm and 12 mm), and the fiber volume fraction (50% and 65%). According to the test results, BFRP bars with the same fiber volume fraction as GFRP bars had much improved mechanical properties (approximately 1.28 times those of GFRP bars). Furthermore, the fiber volume fraction has been shown to have a significant influence on the mechanical properties as well as the creep behavior of BFRP bars. Based on the test results, BFRP bars show a promising future as a substitute for GFRP.
