Effect of dowel wood species on dowel tensile strength in wooden length joints bonded with different adhesives

Abstract

In this study, dowel tensile strength values of wooden length joints prepared using dowels obtained from ash (Fraxinus excelsior Lipsky), chestnut (Castanea sativa Mill.) and oak (Quercus petraea Lieble) were investigated. Experimental samples were prepared from Eastern beech wood. Polyurethane (PU-D4) and polyvinyl acetate (PVAc-D4) glues were used as adhesives. In the experiments, 2 types of glue, 3 species of dowel wood and a total of 60 test samples were prepared from 10 pieces of each sample. The tests were carried out under static load according to BSI 6948 standards. According to the test results, the highest dowel tensile strength value was obtained in the test specimens prepared with ash dowel and polyvinyl acetate (PVAc-D4) glue, the lowest dowel tensile strength value was obtained in the test specimens prepared using polyurethane (PU-D4) glue with chestnut dowel.
