Kostensparende Holzverbindungen durch eingeleimte Metallbleche unter Verwendung neuartiger Kleber mit erhoehter Leimfugendichte. T. 1 Text, Kurzfassung

The influence of joint thickness, temperature and static load duration on the adhesive strength of metal plate in glued adhesive wood joints was investigated. Based on previous investigations and additional screening tests, 4 adhesive materials were selected for a more intensive investigation; polyurethan PU 2 (two-component adhesive), polyurethan PU 4 (one-component adhesive), the conventional epoxide resin EP 1 and the flexibilized epoxide resin EP 2b. On account of a two large compliance, PU 4 is not suited for application. The flexibilized epoxide EP 2 b possesses a high adhesive strength at 20 C, which, however, strongly decreases with increasing temperature. PU 2 exhibits improved adhesive properties in the temperature region between 20 - 40 . EP1 is suited for application in the whole investigated interval (20-70 C), although EP1 is still not optimized for the present application case.
