Advancing Sustainable Structural Solutions: Hemp Fiber-Reinforced Polymer (HFRP) Reinforcement Bars for Concrete Applications through Material Selection, Simulation, and Pathways for Future Development

This paper investigates innovative Hemp Fiber-Reinforced Polymer (HFRP) rebars as a sustainable alternative to conventional Carbon Steel (CS) and Glass Fiber-Reinforced Polymer (GFRP) rebars used as reinforcement in concrete structures. The feasibility of HFRP rebars is assessed, focusing on mechanical properties and sustainability advantages. A virtual tensile test on a modeled M19 HFRP rebar, conducted using Autodesk's Fusion 360, demonstrates tensile strength comparable to CS 235 and greater environmental sustainability than GFRP, despite a slight reduction in stiffness. The study also considers the potential of graphene fiber integration to enhance mechanical properties, underscoring HFRP's adaptability. Findings suggest that HFRP rebars, being lightweight, eco-friendly, and cost-effective, are appropriate for applications requiring moderate strength and durability. However, further studies are essential, including large-scale production trials and rigorous laboratory testing, as well as research on long-term durability in harsh environments, to fully validate HFRP rebars for broader infrastructure applications.
