The Influence of Silica Content on Mechanical Properties of Polypropylene/Wood Powder/Silica Composite

The influence of different contents (0, 5 and 10% W/W)of silica and poplar wood powder ( 30 ,40 and 50% W/W of total weight of composite) on strength properties of Polypropylene/Wood powder/Silica composite was evaluated. Various components of composite was melt mixed using two screw counter retatin...
