Dimensional stabilization of wood treated with furfuryl alcohol catalysed by borates
(Springer, 2004)Furfuryl alcohol has a sufficiently small molecular size, which allows impregnation into wood and can be polymerized in the cell walls. Polymerization can be accomplished using a catalyst, heat or penetrating radiation. ... -
Withdrawal strength and moment resistance of screwed T-type end-to-side grain furniture joints
(Forest Products Soc, 2004)Tests were carried out to investigate the withdrawal strength and bending moment resistance of screwed T-type, end-to-side grain joints constructed of Turkish beech (Fagus Orientalis L.), European oak (Quercus petraea L.), ... -
Withdrawal capacity of pinned and unpinned round mortise and tenon furniture joints
(Forest Products Soc, 2004)Tests were conducted to determine the withdrawal capacity of cross-pinned round mortise and tenon joints. Tenon diameters ranged from a nominal 0.6 to 1.0 inches. Cross-pins were about one-half the diameter of the tenons. ... -
Bending moment capacity of round mortise and tenon furniture joints
(Forest Products Soc, 2004)Tests were conducted to determine the effect of cross pinning the tenons of round mortise and tenon joints on the bending moment capacity of the joints. Tenon diameters ranged from a nominal 0.6 to 1.0 inches. Cross-pins ... -
Effect of hole diameter, hole distance from the edge, and material properties on lateral pin holding strength of medium density fiberboard and particleboard
(Forest Products Soc, 2004)There is no established standard which evaluates the lateral holding resistance of wood composites. The method of test offered in this study intends to determine the lateral resistance of panels used in case constructions ... -
A comparative study on stability and decay resistance of some environmentally friendly fire-retardant boron compounds
(Springer, 2005)Environmental concern accelerated development of new wood preservatives having low mammalian toxicity in addition to high protective effectiveness. PHN 130 and PHN 130 G have been developed recently by KOHMIX Ltd. in Japan ... -
A new boron impregnation technique of wood by vapor boron of boric acid to reduce leaching boron from wood
(Springer, 2005)This study was designed to reveal impregnation ability and to enhance leaching resistance of boron from borate-treated wood. Vapor boron treatment was applied in cornpressed and uncompressed states at high temperatures ... -
Moment capacity of traditional and alternative T-type end-to-side-grain furniture joints
(Forest Products Soc, 2005)The bending moment capacity of traditional and alternative T-type end-to-side-grain joints constructed of Oriental beech (Fagus orientalis Lipsky), European oak (Quercus borealis Lipsky), and Scotch pine (Pinus sylvestris ... -
Moment resistance of multiscrew L-type corner joints
(Forest Products Soc, 2005)This study investigated the effects of screw diameter and length, loading, board material, board surface condition, and gluing, on moment resistances of three-screw L-type corner joints. Wood-based composite panels utilized ... -
Bending moment capacity of rectangular mortise and tenon furniture joints
(Forest Products Soc, 2005)This study investigated the effects of wood species, adhesive type, rail width, tenon depth, and tenon length oil bending strength and flexibility of mortise and tenon T-type end to side grain joints. Sugar maple, red oak, ... -
