Şeker Kamışı Posası Takviyesi Epoksi Kompozit Performansını Artırıyor

Özet (abstract)

The inherent brittleness and poor wear resistance of epoxy resin (EP) limit its industrial applications. Herein, sugarcane bagasse (BG) was used as a reinforcing filler in BG/EP composites. The effects of BG particle size and content on the mechanical and tribological properties of the composites were systematically investigated. The composite containing 19 wt% of 300–400 mesh BG exhibited a tensile strength of 83.1 MPa and a toughness of 19.6 MJ m −3 , representing increases of 27.6% and approximately 9.7%, respectively, compared with pure EP. Its wear rate was reduced by 96.4%. Scanning electron microscopy showed that BG was uniformly dispersed and embedded in the EP matrix, with close interfacial contact. Energy decomposition and hydrogen-bond statistics from molecular dynamics simulations indicated that hydrogen bonding and van der Waals interactions enhanced the interfacial bonding between the fibers and the matrix. This “island-chain” reinforcement mechanism (dispersed BG domains connected by hydrogen-bond-mediated interfacial interactions) facilitates stress distribution and suppresses microcrack propagation during wear. Preliminary laboratory-scale application tests showed that, following 60 min of cumulative polishing, the mass loss of the 19 wt% BG/EP polishing disc was 53.7% and 45.6% lower than that of the pure EP disc and the commercial resin-based polishing disc, respectively. In the epoxy-flooring braking test, the trolley’s stopping distance on 19 wt% BG/EP was 13.5% shorter than that on pure EP and comparable to that on commercial epoxy flooring. These results provide an experimental basis for the value-added utilization of BG in resin-based wear-resistant functional materials.
