Mechanical 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 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 کاملEffect 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 کاملEvaluation of Water Absorption and its Influence on the Physical-Mechanical Properties of Bamboo-Bundle Laminated Veneer Lumber
To investigate the possibility of using bamboo-bundle laminated veneer lumber (BLVL) as a cooling tower packing material, the water absorption rates, thickness swelling rates, and flexural properties of three different composite materials were studied. The BLVL was combined with either 12% or 24% phenol formaldehyde resin (PF), and the moso bamboo strips were exposed to water baths at three dif...
متن کاملThe Effect of Joint Form and Parameter Values on Mechanical Properties of Bamboo-Bundle Laminated Veneer Lumber (BLVL)
Bamboo-bundle laminated veneer lumber (BLVL) was produced by joint lengthening technology. The objective of this study was to evaluate the effect of joint form and the values of key parameters on mechanical properties of BLVL. Two joint forms, i.e., finger joint and scarf joint, and two corresponding joint parameters, i.e., finger length and scarf angle, were investigated in laminates. The resu...
