Research on Tensile Strength of Wood Single Lap Gluing Joint

The tensile strength of joints is one of the most important indexes which can affect joint quality. The effect of gluing length, specimen width and thickness of wood single lap joints on the maximum tensile load and tensile strength has been researched through the experiment method. The maximum tensile load increases with the increase of gluing length, specimen width and thickness, but the increase degrees are different; the tensile strength is consistent with the increase of gluing length, but does not change obviously with the increase of specimen width and even decreases with the increase of specimen thickness. The conclusions of this paper will have guiding significance for the design of wood single lap joints.
