Abstract :This study was carried out to determine the changes in air-dry density and fiber-parallel compressive strength of basalt fiber-reinforced polymer (BFRP) woven fabrics (WF) and plaster mesh (PSM) reinforced sessile oak laminated timber. One component polyurethane (PUR) glue was used as the adhesive. The BFRPWF abd PSM were added as a reinforcement layer between wood veneers to improve properties of laminated composite material. The BFRPWF and PSM were tested in three different locations non-reinforced laminated oak lumber (LOL), reinforced laminated oak lumber with the BFRPWF (LOL- BFRPWF), and reinforced laminated oak lumber with the PSM (LOL-PSM). Tests were performed on the LOL, LOL- BFRPWF, and LOL-PSM to investigate their air-dry density (δl2), and compression strength (σb). The test results showed that the reinforcement process increased both δl2 and σb parallel to the grains. The LOL-BFRPWF samples give better results than PSM and control samples. Accordingly, the samples of LOL-BFRPWF and LOL-PSM samples have the potential to serve as viable options for both furniture and building materials.
