Özet

This study was carried out to determine the effects of using cast-polyamide on modulus of rupture (MOR) and modulus elasticity (MOE) of oriented strand board (OSB) which were produced in four different conditions. Firstly, control panels were manufactured, and also OSB panels produced by adding cast-polyamide with 20 % - 30 % ratio compare with weight of oven dry wood particle both out layer and inner layer. Phenol formaldehyde was used at 6 % ratio. Strands were used to the production of panels made up 50 % of core layer and 50 % of outer layers. Test panels were pressed in 6 min., 40 kg/cm2 press pressure and 185±3°C press temperature by aiming for a target density of 0.67 g/cm3. The values of modulus of rupture and modulus elasticity were determined by using according to related standard.
