Brashaw. Patrick K. Donahue. Abstract. Thermal modification can increase resistance to biological degradation, reduce equilibrium moisture content, and improve the dimensional stability of solid wood. In this study, oriented strand board (OSB) and two types of plywood were thermally modified as a posttreatment at 1408C, 1508C, 1608C, 1708C, and ...

Mechanical and physical properties of thermally modified plywood ...Thermal modification can increase resistance to biological degradation, reduce equilibrium moisture content, and improve the dimensional stability of solid wood. In this study, oriented strand board (OSB) and two types of plywood were thermally modified as a posttreatment at 140°C, 150°C, 160°C, 170°C, and 180°C. Plywood moduli of rupture (MOR) and elasticity (MOE) decreased up to 54 and 22 percent, respectively, at the 180°C treatment, while OSB MOR and MOE decreased ...

post-thermal treatment of oriented strandboard (osb) - SciELOThe objective of this research was to determine the physical and mechanical properties of oriented strandboard (OSB) using strands of Cupressus glauca Lam., before and after a thermal treatment, as well as to evaluate the susceptibility of the boards to fungi attack. boards with nominal density of 0.70 g/cm<sup>3</sup> were produced with 5% and 8% of urea-formaldehyde (UF) resin. Physical and mechanical properties were evaluated according to ASTM D 1037 (1991) standard and compared&nbsp;...

Thermal properties of wood-based panels: specific heat ...It was also shown that high accuracy required for the specific heat measurements was achieved for experiments in which high-mass samples were used, in contrast to measurements for such samples in traditional DSC systems. The results for the specific heat were within the range from 1420 to 1450 J/kg K for LDF and all types of particleboard. The effect of the investigated material density on the specific heat was not found. The only exception was in case of OSB for which the specific&nbsp;...

SELECTED PROPERTIES OF WOOD STRAND AND ORIENTED ...Thermal and mechanical properties of southern pine and willow strands and properties of southern pine oriented strandboard (OSB) from small-diameter logs were investigated in this study. The effects of density and species group on tensile strength, dynamic moduli, and thermal stability of wood strands, and of strand quality (i.e., wood fines) on three-layer OSB properties were analyzed. strand tensile strength and dynamic storage moduli (E) increased with the increase of strand&nbsp;...

Oriented strand board - Wikipediaoriented strand board (OSB), also known as flakeboard, sterling board and aspenite in British English, is a type of engineered lumber similar to particle board, formed by adding adhesives and then compressing layers of wood strands (flakes) in specific orientations. It was invented by Armin Elmendorf in California in 1963. OSB may have a rough and variegated surface with the individual strips of around 2.5 cm × 15 cm (1.0 by 5.9 inches), lying unevenly across each other and comes&nbsp;...

Thermophysical Properties of OSB Boards versus Equilibrium ...The basic thermophysical properties of oriented strand boards were determined experimentally for use in humid conditions (OSB3) depending on the moisture content. The dependency between the thermal conductivity, thermal diffusivity, specific heat capacity, and the moisture content in the range of 0% to 10%, was examined. The non-stationary extended dynamic plane source (EDPS) experimental method was used. EDPS method was modified for anisotropic materials, i.e. with&nbsp;...

The identification procedure was validated and its credibility was assessed. It was shown that data on thermal properties available in the literature should not be recom- mended to model the heat transfer. 1 Introduction. The importance of accurate and effective prediction of heat transfer processes in wood-based panels is increasing with respect to&nbsp;...

Thermal properties of wood-based panels: thermal conductivity ...The effect of temperature on thermal conductivity was not clearly manifested. The thermal conductivity values were decreasing or increasing with temperature. In some cases this influence was practically insignificant (i.e. OSB), while for low density fiberboard the effect of temperature on thermal conductivity was the highest. The identification procedure was validated and its credibility was assessed. It was shown that data on thermal properties available in the literature should not be&nbsp;...

Technical Information - OSBDue to its high mechanical properties and the orientation of the strands within panels, OSB is particularly suitable for load-bearing applications in construction and is widely used for flooring, roof decking and wall sheathing, but there is also a wide field of other applications where OSB as a wood-based panel product can be utilised. Different grades of the product are available for different levels of loading and different environmental conditions. Guidance on the use of OSB in these&nbsp;...
