Special Issue Information

Dear Colleagues,

The decarbonisation of our society can be achieved by increasing the use of wood. In this context, bonded wood products and associated bonding technologies will play an important role in the future. The bonding of wood is a complex process and this technology is based on an interdisciplinary approach covering the fields of chemistry, machinery, and product design. While the understanding of wood bonding has made great progress during the last few years, bonding technologies must be further developed to be competitive. Wood glued products will remain attractive if the adhesive technologies enable, at one time, a fast and sustainable assembly with the material being fully recyclable at the end of its lifetime. The use of green adhesive and innovative curing technologies has demonstrated great potential for solid wood gluing and wood-based panels production. This leads to the need for a better understanding of the field of applications of such advanced technologies.

This Special Issue will cover all the topics from adhesive manufacturing to adhesive curing and bonded wood products. Papers can include reviews and recent unique research on adhesive development, adhesive application and adhesive curing.

Manuscripts can be submitted until the deadline. All submissions that pass pre-check are peer-reviewed. Accepted papers will be published continuously in the journal (as soon as accepted) and will be listed together on the special issue website. Research articles, review articles as well as short communications are invited. For planned papers, a title and short abstract (about 100 words) can be sent to the Editorial Office for announcement on this website.

Submitted manuscripts should not have been published previously, nor be under consideration for publication elsewhere (except conference proceedings papers). All manuscripts are thoroughly refereed through a single-blind peer-review process. A guide for authors and other relevant information for submission of manuscripts is available on the Instructions for Authors page. Forests is an international peer-reviewed open access monthly journal published by MDPI.

In this study, varying ambient climates were simulated in a test building by changing temperature and relative humidity. Beech glued laminated timber (glulam, Fagus sylvatica, L.) was freshly installed in the test building and monitoring of the change in wood moisture content of the glulam resulting from the variations in climate was carried out. Subsequently, finger-jointed beech specimens were exposed to the variations in relative humidity measured in the course of the monitoring experiment on a laboratory scale, and thus an alternating climate regime was derived from the conditions in the test building. Its influence on the delamination of the finger-joints was evaluated. In addition, it was examined whether beech finger-joints using commercial adhesive systems fulfil the normative requirements for delamination resistance according to EN 301 (2018) and whether different bonding-wood moisture levels have an effect on the delamination of the finger-joints. In the context of the monitoring experiment, there was a clear moisture gradient in the beech glulam between the inner and near-surface wood. The applied adhesive systems showed almost the same delamination resistance after variation of relative humidity. The normative requirements were met by all PRF-bonded and by most PUR-bonded beech finger-joints with higher bonding wood moisture content. Full article
