Abstract

The objective of this research was to investigate effects and interactions of extruding factors on the mechanical and physical properties of composites produced from recycled polypropylene and rubberwood flour. Central composite design (CCD) and response surface methodology (RSM) were applied to study the effects of temperatures in zones 1 and 2, as well as screw rotation speed of a twin-screw extruder. The results revealed that an increase of temperature in zone 1 resulted in increased tensile strength (TS) and hardness, but the modulus of rupture (MOR) and water absorption (WA) of the composites were reduced. Increased temperature in zone 2 decreased the TS and MOR of the composites, but the hardness and WA clearly increased. Furthermore, the TS, MOR and WA of the composites decreased with an increase of screw rotation speed, but hardness increased.
