Variations were as follow: -Combinations of Eucalyptus and Poplar wood were (%100, %0), (%66.5,%.5), (%.5,% 66.5) and (%0,% 100) respectively. -Resin content ( %8 and %10) Physical and mechanical properties of boards such as MOR, MOE, IB, TS2 and TS24 were examined accordin to EN standard. The effects of various raw materials combinations on bendin properties were sinificantly different. Maximum of MOE and MOR were observed in %66.5 of Poplar wood and %.5 of Eucalyptus wood. s expected, Physical and mechanical properties of boards were improved by increasin of resin content. Results indicated that TS2 and TS24 were increased with increasin of Poplar wood in combinations. lso the lowest amounts of these properties were obtained in eucalyptus and poplar wood mixture of %100 and %0 respectively. Keywords: Particleboard, poplar, eucalyptus, resin and MOR.
