Abstract Scope |
Field-retted natural bast fibers, such as jute, can be an ideal candidate for selecting as reinforcement in biobased polymer matrix polylactic acid (PLA), with the objective of manufacturing fully biodegradable composites. However, producing high reinforcement content (fiber packing) with degradable matrices without chemical treatment is troublesome. Moreover, field-retted fiber comes with a lot of technical fiber (fiber bundles together) that may not be able to fully separate even after chemical treatment. In this work, we address this issue with the concept of developing a new dry fiber architecture preform based on the individualization of technical fiber, where all the fibers are aligned in parallel direction. This concept enables us to ensure the highest amount of fiber packing in the preform as well as in the composites without any physical or mechanical damage to the fibers. The newly developed composites provided maximum mechanical properties compared to the analogs reported in the literature. The higher packing of fiber (50%) and single fiber strength (~350 MPa) and stiffness (~30 GPa), compared to the technical fiber strength (~158 MPa) and (~12 GPa), influenced higher reinforcement of fiber in the composites and PLA matrix degradability. Overall, this work opens up the opportunity to manufacture environmentally prevailing structural composites in the context of a circular bioeconomy. |
