Impact Bending Strength as a Function of Selected Factors

Milan Gaff, Daniel Ruman, Vladimír Záborský, Vlastimil Borůvka


This article examines the influence of selected factors (wood species, densification, thickness, glue type, and number of cycles) on the impact bending strength (IBS) of solid and laminated wood. The evaluated properties were measured on samples of European beech (Fagus sylvatica L.) and common aspen (Populus tremula L.). Two types of glues were used for laminated wood: polyvinyl acetate (PVAc) and polyurethane (PUR). The highest IBS values were recorded in laminated beech specimens glued with polyvinyl acetate glue that were not subjected to cyclical loading.
