The Effects of Some Factors on the Impact Bending Strength of Laminated Veneer Lumber
In this study, the impact bending strengths and specific impact bending strengths were determined for solid wood and laminated veneer lumber (LVL) produced from eucalyptus (Eucalyptus grandis W. Hill ex Maiden), poplar (Populus x euramericana I-214), and beech (Fagus orientalis L.) woods using urea formaldehyde (UF), melamine urea formaldehyde (MUF), and phenol formaldehyde (PF) adhesives. The ...
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...
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 کاملthe effect of taftan pozzolan on the compressive strength of concrete in the environmental conditions of oman sea (chabahar port)
cement is an essential ingredient in the concrete buildings. for production of cement considerable amount of fossil fuel and electrical energy is consumed. on the other hand for generating one tone of portland cement, nearly one ton of carbon dioxide is released. it shows that 7 percent of the total released carbon dioxide in the world relates to the cement industry. considering ecological issu...
Effects of Press Pressure on Glue Line Thickness and Properties of Laminated Veneer Lumber Glued with Melamine Urea Formaldehyde Adhesive
Laminated veneer lumbers (LVLs) were manufactured from half-round sliced I-214 hybrid poplar clone veneers with MUF adhesives using press pressures ranging from 2.5 to 15 kg cm -2 . The results showed that the press pressures affected the glue line thickness (GLT) and the physical and mechanical properties of the LVLs. Higher specific gravity (SG) and mechanical properties, but lower GLT were d...
