Effect of Boric Acid Treatment on Mechanical Properties of Laminated Beech Veneer Lumber
In spite of many alternative materials like iron, plastic, and concrete, which can be used instead of solid wood in different areas, wood remains superior as a natural engineering material. Due to depletion of forest resources, forest products industries are faced with a crisis in obtaining suitable raw materials in suffi cient amount. Therefore, layered composite materials like vertically and ...
متن کاملAnalysis of the Microstructure and Mechanical Properties of Laminated Veneer Lumber
In this paper, four different nondestructive testing (NDT) methods and static bending tests were done on poplar (Populus ussuriensis Kom.) and birch (Betula platyphylla Suk.) Laminated Veneer Lumber (LVL). The effects of compression ratio on the modulus of elasticity (MOE) and modulus of rupture (MOR) of LVL with vertical load and parallel load were investigated. There were four compression rat...
متن کاملMechanical Properties Analysis and Reliability Assessment of Laminated Veneer Lumber (lvl) Having Different Patterns of Assembly
Laminated Veneer Lumber (LVL) panels made from poplar (Populus ussuriensis Kom.) and birch (Betula platyphylla Suk.) veneers were tested for mechanical properties. The effects of the assembly pattern on the modulus of elasticity (MOE) and modulus of rupture (MOR) of the LVL with vertical load testing were investigated. Three analytical methods were used: composite material mechanics, computer s...
متن کاملDetection and Location of Defects in Laminated Veneer Lumber by Wavelet Package Analysis
Large numbers of vibration signals of wood-based panels are unsteady and complicated, which means that detection can be difficult. The wavelet transform is an effective method to detect these signals, which are otherwise difficult to detect using the Fast Fourier Transform (FFT). This paper presents a study on nondestructive detection of bubble defects seen in poplar laminated veneer lumber (LV...
متن کاملDetermination of Screw Withdrawal Strength of Heat- Treated and Reinforced Laminated Veneer Lumber
The withdrawal resistance of screws in heat-treated and reinforced laminated veneer lumber (RLVL) was determined in the radial, tangential, and transverse directions. For this reason, laminated veneer lumber (LVL) and RLVL with carbon fibers were produced from heattreated oak (Quercus petraea (Liebl.)) veneers using phenol formaldehyde as the adhesive. Wood samples were heat-treated at 140, 170...
