Isıl işlem uygulanmış, karbon fiber ve cam fiber ile güçlendirilmiş lamine kaplama kerestelerin (LVL) bazı fiziksel ve mekaniksel özellikleri.

Wood is one of the oldest widely used building materials. There is an increasing demand for its use in different areas for different purposes. In order to meet this demand, wood-based structural composites have been developed. In this study, some physical and mechanical properties of laminated composite samples obtained from beech (Fagus orientalis Lipsky) wood, which were heat treated and reinforced with carbon and glass fiber using phenol formaldehyde (FF) glue, were investigated. For this purpose, heat treatment was applied to wood materials at 150, 175 and 200°C for 3 hours and test samples were prepared. Density (D), modulus of elasticity in bending (MOE), bending strength, (MOR) compressive strength parallel to grains (CS//) and bonding strength parallel to grains (SS) were determined for the test samples. The test results showed that the bending strength (MOR) and modulus of elasticity in bending (MOE) values of the reinforced samples with carbon and glass fiber increased. However, while it caused significant changes in the compressive strength parallel to the grain (CS//) values depending on the applied heat treatment temperature and the type of reinforcing material, decreases in the bonding strength parallel to the grain (SS) values were determined. In general, the MOR and MOE values of the reinforced test samples with carbon fiber were higher than the reinforced samples with glass fiber, while the CS// and SS values were lower.
