Structures Obtained from Thin Wood of Spruce and Maple, by Lignin Activation

Abstract

The wood obtained from forest thinning, with small dimensions (Ø=14 cm), is today a potential raw material for furniture design. The main objective of the paper is to present the possibility of obtaining new structures by an innovative method of joining. Two species, a resinous one (spruce, Picea abies L.) and a broad-leaved one (maple, Acer platanoides L.) were selected for this research. The results have shown that the joints between dowels and support are uniform and compact, even if the structures combine two wood species with specific characteristics. The high lignin content of this raw material could be an advantage. The conclusion is that the newly proposed structures represent potential alternatives for the classical joints with adhesive.
