The effect of humidity on the shear strength of glued wood based and plastic joints

Popis výsledku v původním jazyce

The main objective of the paper is to determine the effect of humidity on the mechanical properties of glued structural joints. Shear strength of glued joints is investigated in terms of two environments with specific climatic conditions, it means dry environment of residential and public building interiors at the tempeature of t = 23 +- 2oC, and relative humidity of WR = 45 +- 5% and wet environment at the temperature of t = 23 +- 2oC, relative humidity of WR = 90% +- 5% (bathrooms, laundries, swimming pools). Two types of materials, including their combination, particle board (PB) with the thickness of 12 mm and artificial stone (plastic material) with the thickness of 12 mm were tested. Epoxy and polyurethane adhesives were used for glued lap joints. In general, the air humidity of the environment does not have a statistically significant effect on the shear strength of the glued joints. For bonding the same materials, the maximum value of shear strength were achieved using polyurethane (PUR) adhesive and the material combination - plastic-plastic and air humidity of 90%. For bonding materials with various properties (PB and plastic) epoxy adhesive is the most suitable.
