Water absorption of lignocellulosic phenolic composites
The main objective of this study is to investigate the effect of filler content and filler size on the water absorption behaviour of phenolic composites filled with oil palm shell flour, rice husk flour and coconut shell flour. Lignocellulosic phenolic composites with three different filler sizes (&...

The main objective of this study is to investigate the effect of filler content and filler size on the water absorption behaviour of phenolic composites filled with oil palm shell flour, rice husk flour and coconut shell flour.
