Field of application and prospects of the use of lvl-composites in ukraine
Abstract
Domestic and foreign researchers carried out a detailed analysis of the work of LVL composites abroad and in Ukraine. The field of application and prospects for the use of LVL composites in Ukraine and abroad are highlighted. The area of further perspective research of LVL-composites is given.
Wood is a valuable natural material, and the world’s reserves are decreasing significantly every year. Materials, products, elements, and structures based on the wood of various species are wildly popular, both in Ukraine and far beyond its borders. Ukraine is one of the leading European exporters of raw wood products. Many times in everyday life, at work, and in public places, our eyes are pleased with products made of wood.
Equally important factors are studies of different mechanical characteristics of wood-based materials that work under different types of loads and in different environments. Materials, products, elements, and structures made of glued and modified wood (various composites), including those based on wood veneer, are gaining great popularity. They are used in many industries, including construction. These include LVL composites.
A composite is a material made of two or more components and has new improved properties compared to others. Composite materials usually imitate the best characteristics of the components: increased strength, reduced deformability, resistance to corrosion, lightweight, thermal insulation, etc. Among the main modern wood-based composite materials are: Laminated Veneer Lumber, (LVL), Cross-Laminated Timber (CLT) і Glued Laminated Timber (GLT).
The most promising and innovative among them in the conditions of Ukrainian realities is laminated veneer lumber. LVL is a material made from pine and spruce veneers that are glued together to create a material that is primarily strong and dimensionally stable.
In the future, it is necessary to conduct experimental and theoretical studies of the mechanical properties of the above-mentioned composites under different operating conditions and types of loading from the beginning of loading to destruction, as well as to propose a calculation method.
