- Abstract
In this research effort, the impact of fillers' composition on wood-plastic composites (WPC) made of poly (lactic acid) PLA was tested. The composites varied in filler type (bark, sawdust) and its content in the boards (40, 50, 60%). The composites were manufactured in a two-stage process consisting of extrusion and flat pressing. Analogically prepared HDPE boards were a reference. Composites were tested for density, density profile, and screw-holding ability. Boards based on PLA performed better screw-holding ability than HDPE. The greatest influence was exerted by the share of matrix/filler. An increase in the content of lignocellulosic particles from 40 to 60% (regardless of the type of matrix: PLA or HDPE) generally reduced screw-holding ability. The type of filler (sawdust, bark) was almost 3 times more important in the case of HDPE boards compared to PLA boards.
