Abstract
AbstractThe present study investigates the influence of micron‐sized diatomite dosage on the physical, mechanical, rheological, and creep properties of poplar wood/polypropylene (PW/PP) composites to enhance their toughness and practicality. The diatomite‐PW/PP composites were prepared using the melt extrusion method, replacing different proportions of PW with diatomite, and subsequently evaluated for their properties. The results indicate that adding diatomite enhances the density while reducing the brightness and water absorption of the composites. Scanning electron microscopy, analysis reveals a uniform distribution of diatomite in the range of 5–10 wt%, which effectively serves as a filler and reinforcing agent, consequently improving the toughness of the composite system. Specifically, the impact strength, tensile strength, and elongation at break are enhanced by 25.9%, 9.5%, and 35.7%, respectively. Furthermore, creep rheological analysis demonstrates improved processability and creep resistance in the composite system.
