Special Issue Information

Dear Colleagues,

This Special Issue, entitled “Advances in Timber-Composite Processing and End-Products in Building Design”, will focus on high-quality original research articles and reviews on the latest approaches to the development of wood-based ecological materials, advanced wood processing features, and further advances in research on their industrial production and applications in building design. Wood is one of the oldest known materials in construction. It has been used for centuries to produce natural, renewable building elements that provide an alternative to steel or concrete. Despite the production of some successful and attractive wood-based materials (GLT, CLT, LVL...), wood also has shortcomings and various limitations, such as limited fire resistance, dimensional instability, mechanical anisotropy, creep and mechano-sorptive deformations, and susceptibility to various biotic and abiotic damages. Therefore, the aim of this Special Issue is to provide up-to-date knowledge on the latest processes for manufacturing wood- and lignocellulose-based building materials in order to present building products with improved or modified relevant properties. In addition, this Special Issue also provides space for presenting new technological solutions and identifying features and drawbacks of current materials that need improvement. Therefore, we encourage you to submit scientific papers or reviews on wood-based building products that expand the current knowledge on processing and end-uses, and identify potential new applications.

Beech (Fagus Sylvatica L.) is a prevalent tree species in Slovenia and is suitable for manufacturing glulam beams. However, beech wood has certain limitations that can potentially be mitigated by combining it with Norway spruce (Picea abies (L.) Karst.) wood to create hybrid beams. This study aimed to determine the bonding performance of commonly used melamine–urea–formaldehyde and polyurethane adhesives for these hybrid beams. Moreover, how varying the proportion of beech wood in a hybrid beam affects its mechanical properties was examined. Shear and delamination tests (method B) were conducted, and EN 14080:2013 requirements were met in all cases. The four-point bending tests of the beams showed that hybrid beams containing 20% of beech wood in the cross-sectional height on each side of the neutral axis exhibited a similar modulus of elasticity values as pure beech beams, but their strength was not equally improved. Hybrid beams with 11% of beech wood did not show any improvement in bending stiffness or strength compared to pure spruce beams. It was noted that the presence of beech wood in a hybrid beam can influence its failure mode. Furthermore, analytical calculations showed that a symmetrical lay-up is preferable to an asymmetrical one to increase the effective modulus of elasticity. Full article
