Shear and adhesion strength of open and closed system heat-treated wood samples

چکیده
This paper investigated the effects of heat treatment in open (atmospheric pressure) and a closed (under system on shear adhesion strength Scots pine (Pinus sylvestris) wood. In addition, pull-off adherence testing was carried out coatings with water-based, polyurethane-based oil/wax-based varnishes. Shear decreased significantly after (31 % to 39 %) system, while it between 2 38% without glue. The wood samples glued glue higher than at laboratory scale. lower modified could be attributed other factors, such as reduced chemical bonding or mechanical interlocking adhesives, brittle substrate. With increasing, temperature decreased. Maximum (4,80 MPa) observed control coated varnish.

Shear Bond Strength of Metal brackets to Zirconia Treated with Er:YAG Laser Sandblasting and Silane
Background and Aim: Application of zirconia ceramics has increased. Since the commonly used surface treatment for porcelain, i.e. acid etching is not efficient for zirconia surfaces, evaluation of other surface treatment methods for zirconia is important. The aim of this study was to compare the shear bond strength (SBS) of metal brackets to zirconia treated with different powers of Er:YAG lase...
متن کاملSize Effect in Crack Shear Strength of Wood
It is known for long time that the size of a structure has an important effect on its fracture stress. This phenomenon is called size effect and it seems that it can be attributed to the influence of a damaged zone which develops around the fracture area. Investigations have been made on size effect in shear fracture on two species of wood : Maritime Pine and Norway Spruce. The experimental fra...
