Method & Evidence

AimHow does the stacking sequence and hybridization of glass, carbon, kevlar, and basalt fibers affect the mechanical properties and abrasive wear rate of polymer composites?

MethodExperimental investigation with statistical optimization

ProcedureHybrid composites were fabricated with varying fiber types and stacking sequences. Mechanical properties (tensile and flexural strength) were measured. Abrasive wear tests were conducted using a pin-on-disc tester under different sliding distances and velocities. Response surface methodology (Box-Behnken design) was used to analyze the data, and a firefly algorithm was employed to identify optimal process parameters for minimizing specific wear rate (SWR). Worn surfaces were analyzed using scanning electron microscopy.
