Abstract
This study investigates the effect of wood acetylation on the mechanical properties and creep resistance of wood/recycled-polypropylene composites (WRPCs) using the time–temperature superposition principle (TTSP). The results revealed that the flexural and tensile strength of WRPCs increased with increasing weight percent gain (WPG) of acetylated wood particles up to 13%. Additionally, the TTSP-predicted creep compliance curve fit well with the long-term experimental data. The creep resistance of WRPCs with acetylated wood particles was greater than that of WRPCs with unmodified wood particles, especially for the WRPC with 13% WPG of acetylated wood particles.
