Originální abstrakt

This research aimed to evaluate the shear strength of the lap joints of beech wood. A one-component polyurethane adhesive, filled with basalt fibers, for waterproof joints, was used for bonding. The shear strength of the bonded joint was determined according to standard EN 302-1. It was found that the shear strength of the bonded joint is higher for wood that was glued with filled one-component polyurethane in the amount of 3% basalt fibers. While the average value of the shear strength of lap joints glued with one-component polyurethane without the filler in the hydrothermal stress was 8.8 N/mm2, the lap joints with basalt fibers achieved more than a 14% higher average shear strength of 10.1 N/mm2. For wood that was bonded with the modified adhesive, the experimental measurement also showed a higher proportion of joint failure in the wood than in the adhesive, as was the case with the reference bonded with one-component polyurethane without basalt fibers.
