Research of strength of gluing of wood

IOP Conference Series: Earth and Environmental Science, 2020
Abstract Wood is widely used in industrial and civil engineering. It has many valuable physical, mechanical and other operational properties that make it widely possible to use it not only in construction, but also in other sectors of the economy.

ARCHES WITH GLUED WOOD. THE HISTORY OF DEVELOPMENT

Current problems of architecture and urban planning, 2021
Building structures made of solid and glued timber have long been widely used in many countries of the world, they have existed for several centuries. Their appearance is due to the fact that the available material, wood of natural origin, often could not be obtained with the desired section and quality.

Rotational wood welding: Mechanical properties of thermally treated oak [PDF]

Glasnik Šumarskog Fakulteta: Univerzitet u Beogradu, 2022
The paper examined the strength of rotationally welded joints between untreated beech dowels and samples of thermally modified and unmodified oak wood (used as substrates). The results were compared with the control group where beech dowels were

On the Endurance of Glued-Laminated Wood

journal of the Japan Society for Testing Materials, 1962
In the present report we have experimented on the bending fatigue strength of glued-laminated wood which is made of Japanese cypress and is glued with urea resin or phenol resin. For comparison, same experiments have been carried out also on solid Japanese cypress and beech with controled moisture content and air dried.

OVERVIEW OF GLUED WOOD BUILDING MATERIALS

Materials of the All-Russian scientific and practical conference "Modern machines, equipment and IT solutions for industrial complex: theory and practice", 2021
Currently, environmental friendliness is one of the main requirements for products of any kind all over the world. The use of wood as a building material fully meets this requirement. Every year the share of wooden housing construction increases, and not only in the segment of low-rise, but also multi-storey wooden houses and structures.

Researches on influence of wood sanding direction on wood gluing

Journal of the Indian Academy of Wood Science, 2022
AbstractThe wood surface quality is most determined by the way in which it has been processed before and by the tools used for this purpose. Machining has its effect primarily on the structural shape of the surface formed after the tool–wood contact and also on the roughness of the surface obtained after a specific process. In most cases, wood surfaces

Competitive polycondensation of model compound melamine-urea-formaldehyed (MUF) resin system by 13C NMR

Journal of Bioresources and Bioproducts, 2020
Melamine-urea-formaldehyde (MUF) resin is an excellent adhesive in the field of wood adhesives, however the competition mechanism is questionable which affects the structure control and performance optimization of the resin.

Study of the Antagonism of Biocontrol Strains Against the Blue-Stain Fungus of Rubberwood

Journal of Fungi
Wood blue staining is one of the most common wood defects, which commonly occurs in rubberwood and Masson pine. It not only affects the appearance of the wood, but also its properties. In this study, rubberwood from Xishuangbanna was examined. During the
