TEMPERATURE AND HUMIDITY INFLUENCE ON THE STRENGTH OF THERMOPLASTIC ADHESIVE JOINTS OF SOFTWOODS

B.Ya. Kshyvetsky

Abstract


Using pine wood as an example, the results of studies of the effect of ambient humidity and temperature on the strength of thermoplastic adhesive joints of softwoods under operating conditions are given. In the studies, a mathematical model was used to predict the strength of thermoplastic adhesive wood joints. As a result of the studies conducted, it was found that the strength and water resistance of thermoplastic adhesive joints of pine wood are strongly dependent on the structure and chemical components of pine wood itself as well as whether cross-linked or uncross-linked PVA compositions are used. The investigation also gives an insight into the pattern of change in the strength of thermoplastic adhesive pine wood joints according to varying ambient humidity and temperature.
