| Abstract Scope |
This study explores the use of recycled polyethylene terephthalate (PET) fibers as reinforcement in concrete structures, focusing on improved mechanical performance and sustainable material development. PET fibers were added at a 0.5% volumetric ratio and evaluated through both physical testing and finite element modeling. Four-point bending tests were simulated using ANSYS to assess structural behavior under realistic loading conditions, comparing fiber-reinforced and plain concrete beams, with and without notches. The addition of PET fibers enhanced ductility, delayed crack initiation, and redistributed stresses, leading to more resilient structural performance without significantly compromising compressive strength. Numerical models confirmed reduced stress concentration and increased deformation capacity in fiber-reinforced configurations. These results highlight the potential of recycled PET fibers to contribute to durable, eco-efficient concrete technologies, while demonstrating the value of integrating experimental data and computational simulations in the design of fiber-reinforced cementitious composites. |
