Effect of cemical modification of lignocellulosics fiber on physical and mechanical properties in MDF

The goal of this study was to investigate the use of bagasse fibers as raw material for making laboratory medium density fiberboard (MDF). Effect of treatment (with maleic anhydride and without maleic anhydride) of fibers and the press temperatures (180 ºC , 190 ºC , and 200 ºC) on the mechanical a...
