THEORETICAL EVALUATION OF THE ORIENTATED PARTICLEBOARD'S MODULUS OF ELASTICITY BY MICRO-MECHANICS

Based on the composite mechanics, the micro-mechanics model the orientated particleboard was founded Utilizing probability theory, the modulus of elasticity (MOE) of the orientated particleboard in main direction was obtained and the theoretical evaluation of MOE of the orientated particleboard was solved and the conlusions are verified indirectly It is an attempt to apply modern design method and micro-mechanics to man-mand board mechanics and will put forward the study of computer imitation of the orientated particleboard The conclusions in this paper also can be applied of different kinds of trees So we can design particleboard according to different requirements of strength, different ratio of different kinds of trees and the best oriented angle square difference to achieve the most satisfactory structrue and the strength proportion of vertical and horizontal direction
