The Influence of Alternating Lower and Higher Temperatures on the Bending Characteristics of Glued Norway Spruce (Picea abies (L.) H. Karst.) and European Larch (Larix decidua Mill.) Wood

Popis výsledku v původním jazyce

This article deals with the effect of alternating lower (freezing) and higher (heating) temperatures on the static bending characteristics of glued Norway spruce (Picea abies (L.) H. Karst.) and European larch (Larix decidua Mill.) wood. Two types of wood, PUR (polyurethane), and EPI (emulsion polymer isocyanate), were used for the experiment. The thermal loading of glued wood was carried out at temperatures -15 degrees C/70 degrees C and -25 degrees C/70 degrees C. Static bending characteristics were determined on glued wood samples and compared with the reference samples. Freezing causes an increase in the bending properties of both glued spruce and larch wood. The highest in bending strength was obtained for EPI-glued larch wood subjected to -25 degrees C/70 degrees C loading temperature, which is by as much as 20% increase from the reference value. The maximum improvement in the modulus of elasticity was achieved for EPI-glued larch with around 11% increase, although the increased values of bendi
