Bio-based epoxy resins are limited by high melt viscosity (η∗> 50 Pa s at 25 ◦C) 3, 61 and insufficient mechanical performance (tensile strength 100 MPa, glass transition temperature Tg > 120 ◦C, topology freezing temperature 40 85% 71. This study constitutes the first reported fully hemp-derived vitrimer composite system and establishes processing–structure–property relationships for recyclable, structural-grade biocomposites.
