THE GLUING OF WOOD WITH SYNTHETIC ADHESIVES

South African Forestry Journal, 1964
SUMMARY The bonding of wood by means of glue has been practised for many centuries. Adhesion between an adhesive and wood is the result of unbalanced secondary valency forces (Van der Waal's forces) present on the interfaces. It is fundamental to good adhesion that the adhesive must (a) wet the surface it is required to adhere to and (b) penetrate the ...

Gluing Wood in Aircraft Work

Transactions of the American Society of Mechanical Engineers, 1928
Abstract The author discusses the glues used in aircraft, and describes the gluing operation and its application to different species of wood. He also makes recommendations for the gluing of different woods with both animal and casein glues, giving data on glue-water proportions, glue spread, temperature of wood, pressure to be applied ...

Glued Laminated Wood Construction in Europe

Journal of the Structural Division, 1958
History and current status of wood laminating industry in Europe; adhesives, wood species and production methods varying from United States practices; more efficient design by use of I-beams enables European engineers to save up to 25% lumber and still provide stiffer construction than comparable American rectangular beam designs.

Structural panel of lamelada wood glued crossed

2023
Engineered wood products have their commercial origin in the 19th century. Through the union of the seals with the aid of a waterproof adhesive, the system proved stronger than the lumber itself rekindling the interest in wood constructions, which declined after the period of the industrial revolution (ZMIJEWKI; WOJTOWICZ-JANKOWSKA, 2017).

The strength of press-glued and screw-glued wood-plywood joints

Holz als Roh- und Werkstoff, 2003
The effects of screw-gluing and gap-filling phenol resorcinol formaldehyde (GPRF) adhesive using different glue line thicknesses on the shear strength of wood-plywood joints were studied to determine the use of screw-gluing fastening (SG) method and GPRF adhesive.

Resistance-curves and wood variability: Application of glued-in-rod

International Journal of Adhesion and Adhesives, 2016
Abstract The current study investigates the withdrawal strength of glued-in rods as part of linear elastic fracture mechanics. An experimental campaign was performed in order to observe the effect of the specie (spruce and oak) on the axial strength of glued-in rods for given geometrical configurations.

Quality assessment of glued ash wood for construction engineering

European Journal of Wood and Wood Products, 2015
Delamination resistance and tensile shear strength (TSS) are essential for load-bearing timber structures. Thus these two factors were investigated on industrially bonded ash wood (Fraxinus excelsior L.) to check for the suitability of adhesively bonded ash wood as a building material. Two melamine urea formaldehyde (MUF) resins, two polyurethanes (PUR)

Radio-Frequency Heating Applied to Wood Gluing

Proceedings of the IRE, 1943
Dielectric heating by radio-frequency power has been established as a practical means for rapidly gluing wood with thermosetting adhesives. To the radio engineer, such an application involves the correlation of power concentration, frequency, voltage gradient, dielectric constant, and power factor for the determination of reasonable operating ...

The prediction of damping in nailed and glued wood structures

Journal of Sound and Vibration, 1971
Abstract Improvement of damping of small amplitude vibrations can be obtained by properly optimizing glued and nailed joints. In this paper methods for accurately predicting such damping are developed which require simple tests on small specimens. The analytical predictions are confirmed by experiments on structural members. These results can lead to

Development of Wood Adhesives and Gluing Technique

Journal of Fluids Engineering, 1932
Abstract Study of adhesives used in furniture and other relics of earlier civilizations yields little of value to present-day craftsmanship. This paper therefore discusses only the more recent developments in glues and the technique of using them.
