Thermal and Rheological Properties of Hemp Fiber/Polybutylene Succinate (PBS) Composites

Abstract:

Natural fiber reinforced biopolymer composites have gained attention due to their eco-friendliness, biodegradability, sustainability, and mechanical properties. In this study, hemp fiber-reinforced polybutylene succinate (PBS) composites were prepared with various fiber loadings ranging from 0 to 40 wt%, with increments of 10 wt%. The hemp fibers were treated with NaOH to remove impurities on fiber surface. The thermal and rheological properties of hemp fiber/PBS composites were analyzed. The results indicated that the addition of hemp fiber significantly enhanced the rheological properties, with increased fiber concentration. However, the thermal properties of the composites did not improve with the addition of hemp fibers because of the lower thermal stability of natural fibers. The optimal hemp fiber concentration in PBS matrix was 30 wt% since it provided a balance between thermal and rheological properties.
