Many polymer systems still struggle to achieve an optimal balance of properties, particularly when recycled components are integrated. The inherent brittleness of recycled polyethylene terephthalate (RPET) and its limited compatibility with other polymers restrict its use in high-performance engineering materials.

Abstract Despite the increasing interest in recycled polymer composites and natural fiber reinforcement, relatively few studies have systematically examined low-density polyethylene (LDPE)/recycled polyethylene terephthalate (r-PET) blend systems reinforced with cellulose fibers recovered from used disposable paper cups, particularly through a direct comparison of untreated and methacrylic acid-grafted fibers.
