| Summary: | The effects of plastic grades and composition contents on creep behavior of extruded
composites from polypropylene and rubberwood flour were investigated. Virgin polypropylene
gave lower creep strain than recycled polypropylene, both in composites and as unfilled plastic. An
increase of rubberwood flour content reduced the creep deformation of the composites, both virgin
and recycled plastics. Maleic anhydride-grafted polypropylene as a coupling, 5 wt% addition
increased the creep strain of the composite materials. Likewise, an addition of 1 wt% ultraviolet
(UV) stabilizer content significantly enhanced the creep deformation. The results recommend that
the amount of UV stabilizer should be as small as possible to limit its negative effects. Fourelement
Burger model offered a good fitting on the creep behavior of each composite formulation. |
