Abstract
This paper presents an experimental research aimed in increasing the bending strength performance of selected timber members made from Yellow Meranti and Bintangor species. A series of glass fiber reinforced polymer (GFRP) strips are glued on the timber face with different pattern alignment, which is diagonal (45°) and straight (90°) that is bonded using epoxy resins in order to increase the bending strength. The bending strength test under three-point loading was conducted for solid timber member for the respective species accordance to ASTM D143-09: 1992. The results shown the timber member reinforced with the GFRP strips slightly improved by 2 and 5 % of the bending strength. The failure modes of the selected timber specimen were also observed. Both controlled specimens shown visible damage that is cracking at mid-span for Yellow Meranti specimen and shear failure for Bintangor specimen. While, for reinforced specimens, some of the specimens possess no visible damage and some possess the shear failure.
