Improving the Tensile Shear Strength of Lap Joints of Beech Wood by Adding Basalt Fibers to Polyurethane Adhesive
Original language description
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.
