ABSTRACT
This study aims to increase the bending strength of glulam beam with Basalt-Bioplastic FRP. Bioplastic is bio-based plastic which does not use petroleum-based materials. This study uses FRP which uses the basalt fiber as the reinforcing fiber and the unsaturated polyester containing 26% bio-based plastic. The Basalt-Bioplastic FRP plates were inserted into the glulam beam on upper and lower sides. This study first conducted material test of Basalt-Bioplastic FRP. The results showed that Basalt-Bioplastic FRP has almost the same tensile strength as Glass FRP (GFRP), which made Basalt-Bioplastic FRP reliable material for structural reinforcement. Secondly, the four-point bending tests were conducted with the glulam specimens with 2160 mm in span length. Two types of the specimens were prepared: unreinforced specimens and reinforced specimens with the Basalt-Bioplastic FRP. Four-point bending tests on three specimens for each types revealed that the reinforced specimens had higher bending strength than the unreinforced specimens.
