| Abstract: | An drei verschiedenen Klebstoffen wurde der Einfluss von Temperatur und relativer Luftfeuchte auf die Scherfestigkeit im Zugscherversuch geprüft. Es wurden zwei handelsübliche Klebstoffe (PVAc, Harnstoffharz) und ein labortechnisch hergestellter 1KPUR bei erhöhter Temperatur und relativer Luftfeuchte geprüft. Ergänzend wurde mittels Video Image Correlation die Verzerrung im Bereich der Klebfuge ermittelt und daraus ein Schubmodul der Klebfuge berechnet. Studies on the influence of temperature and timber moisture on the failure behaviour of selected adhesives under tensile shear load. The influence of temperature and relative humidity on shear strength was tested in a tensile shear test with three different adhesives. Two standard adhesives (PVAc, urea resin) and a 1KPUR (one-component polyurethane adhesive) produced in the laboratory were tested at a high temperature along with relative humidity. In addition distortion around the glue joint was measured by means of video image correlation and a shear modulus of the glue joint calculated from this. |
