Influence of date-palm-fibers (DPFs) content and nanocrystallite FeCrCuMnTi high-entropy alloy fillers in polypropylene matrix on mechanical and structural performance of thermoplastic composite materials
Investigation of mechanical properties in polypropylene composites with date palm fibers and high-entropy alloy fillers, suggesting enhanced performance.
Key Points
The PP-5DPFs (75 µm)-2.5HEA composite significantly improved tensile strength by 41.9% compared to neat PP.
Field emission gun scanning electron microscopy revealed strong fiber-matrix adhesion with minimal voids in composites.
Smaller fibers (75 µm) provided enhanced dispersion and bonding, while larger fibers (150 µm) led to aggregation and inefficiency.
High-entropy alloy fillers effectively boosted crystallinity and stress distribution, minimizing the effects of fiber aggregation.
