The present study deals with the physical and mechanical properties of dry-formed medium density fibreboard (MDF) made from renewable biomass kenaf (Hibiscus cannabinus L.) stem as a function of adhesive level and refining conditions. Raw material was prepared by heating for 5 min at pressure levels of 6 and 8 bars. Experimental samples with a target density of 700 kgm -3 were produced with 10,...

The characterization of poplar wood assumes a strategic position to increase the competitiveness entire forest supply chain. From this aspect, identification quality represents primary objective for researchers and private landowners. can be defined via traditional visual methods based on experience technicians or using tools, such as incremental drills sound hammers. properties these traits, o...

This work elucidates on a case study of industrially manufactured cross-laminated timber (CLT). Two methods are used to calculate specimens section modulus: Sgross and Seffective. The first assumes that behave as continuous material, whereas the second considers cross laminations (shear analogy method). Although shear method is indicated for construction purposes, applications, such trench shori...

For the sake of improving product quality and economy, a series cold-pressing experiments were carried out to investigate material properties engineered wood flooring with emulsion polymer isocyanate adhesive. Effect pressing time, pressure, adhesive spreading rate on modulus elasticity (MOE) rupture (MOR) was analyzed based orthogonal experimental design. According results, both MOE MOR positi...

vibration generated by vehicles during road transport has an important effect on the agricultural products damage process, particularly vegetable and fruit. modulus of elasticity is one of the most important mechanical properties of fruits and its variation can be described as one of the damage criteria during transportation. this research was conducted to evaluate the effects of vibration para...

The density and modulus of elasticity (MOE) distribution can provide information on the effectiveness parametric non-parametric methods in calculating characteristic value MOE. In this study, we aim to determine optimal model actual measured data lumber. We also estimate lumber’s MOE compare difference between natural planted larch. Approximately 1200 pieces dimension lumber 4 m × 140 mm 40 siz...

YU, H. Q., JIANG, Z. H., HSE, C. Y. & SHUPE, T. F. 2008. Selected physical and mechanical properties of moso bamboo (Phyllostachys pubescens). Selected physical and mechanical properties of 4–6 year old moso bamboo (Phyllostachys pubescens) grown in Zhejiang, China were investigated at different vertical and horizontal positions. Two way analysis of variance and Tukey’s mean comparison tests in...

To effectively improve the strength of Plectocomia pierreana rattan cane without reducing its toughness, the cane was impregnated with a new water-soluble melamine-urea-formaldehyde (MUF) resin modified with low-molecular-weight polyethylene glycol (PEG), marked as PMUF. The PMUF synthetic process was optimized using an orthogonal test L9(3). Results showed that the dimensional stability, densi...

Carbon fiber fabric reinforced laminated veneer lumber (RLVL) pieces were prepared by using heat-treated beech (Fagus orientalis Lipsky) veneers with polyurethane (PU) adhesive as the binder. was tested in three different locations solid material and non-reinforced samples (on bottom line, upper lines-symmetrical). Prior to manufacture of LVL RLVL, heat treatment conducted a laboratory oven at ...
