THE EFFECT OF MAT MOISTURE CONTENT GRADIENT ON PHYSICAL & MECHANICAL PROPERTIES OF PARTICLEBOARD

In this investigation, experimental boards were produced using beech wood particle, mat moisture content gradient at 0,3 and 6%, two press temperature sat 165and 1850 C and two press times at 3 and 5 minutes. 36 sample boards produced and the physical and mechanical properties of those tested.The re...
