Investigation on the effect of press temperature and time on physical and mechanical properties corn stalk MDF

The objective of this investigation was the utilization of corn stalk in Medium Density Fiberboard (MDF) production. Therefore 27 laboratory MDF boards were produced using three press temperatures of 165, 175 and 185 °C and three press duration of 3, 3.5 and 4 minutes. The mechanical and physical pr...
