摘要

This research investigates the mechanical, wear, water absorption, and flammability properties of polyester composites reinforced with PET core treated with silane, waste glass fiber plastic particles, and tanned leather fibers. Composite fabrication involved layering silane-treated PET core and tanned leather fibers within a polyester-glass fiber matrix, followed by curing and post-curing processes.The findings show that specimen A2, which contains 40 vol% industrial leather and 3 vol% silane-treated GFRP filler, performs better in a variety of tests. A2 obtained a coefficient of friction of 0.32, a specific wear rate of 0.019 mm³/Nm, a tensile strength of 141 MPa, and a flexural strength of 161 MPa. The composite’s exceptional flame-retardant qualities and resistance to moisture are demonstrated by its low water absorption of 0.43% and UL-94 V-0 flammability rating, which has a flame propagation speed of 9.78 mm/min. The consistent dispersion of silane-treated filler, which improves wear resistance, thermal stability, and stress distribution, is responsible for these gains. Specimens B2 and C2 (3 vol% GFRP filler) only slightly decreased in performance during service circumstances. After 30 days of age at 50 °C, B2 retained a flexural strength of 156 MPa and a tensile strength of 136 MPa. C2 maintained a tensile strength of 124 MPa and a flexural strength of 149 MPa following 30 days of age at 70 °C. The findings show that silane treatment significantly improves the composite’s resistance to service conditions by enhancing interfacial adhesion. Improved adhesion and even filler dispersion in A2 were found by SEM analysis, which helped to maintain mechanical properties. All things considered, the study shows that these composites have excellent wear performance, flame resistance, and durability, which makes them appropriate for a variety of uses in the automotive, aerospace, and marine industries.
