Hemp Rebar Added to Library at Material ConneXion
September 10th, 2025
This Summer, Hemp Rebar developed by FibreWerks Inc., led by Associate Director of CASE Dr. Alexandros Tsamis, was added to the Material Connexion (MCX) material library. Material ConneXion is a world-class materials library and consultancy. With a library of over 10,000 innovative and sustainable material alternatives, MCX works with companies to update their “current manufacturing supply and support product ideation by finding and recommending materials that enhance performance, aesthetic, and sustainability.” (Material ConneXion, 2025).
Hemp Rebar was added to the Naturals, Polymers, Composites categories of the library. This composite rebar is a hemp-based natural fiber-reinforced thermoplastic (NFRT) solution. It is a non-corroding bio-composite reinforcement material designed for use in cementitious applications. The composition of this material is 50% hemp fiber and 50% polypropylene or other bio-derived or upcycled thermoplastics. The integration of hemp fibers provides mechanical strength, while thermoplastics ensure durability and processing flexibility. Hemp Rebar is a non-corroding and non-magnetic composite which makes it a robust alternative for construction applications requiring long-term durability and low maintenance. The technology covers all conventional diameters found in steel, stainless steel, or fiberglass rebar, making it adaptable to standard construction specifications. It is also particularly advantageous in environments prone to high corrosion, such as coastal and marine regions, as well as roads and pavements exposed to heavy salt usage.
CASE is excited to announce this achievement from RPI’s spinout company, FibreWerks, and to have Hemp Rebar gain recognition alongside thousands of groundbreaking materials that are paving the way for a more sustainable and resilient built environment. You can view the Hemp Rebar sample amongst others in the robust material library at Material ConneXion in New York City by appointment only.
