Mechanical and Tribological Behavior of Hybrid Polymer and Hybrid Sandwich Composites

The present chapter addresses the mechanicalMechanical and tribologicalTribological behavior of advanced particulate, hybridHybrid polymerPolymer and hybridHybrid sandwich compositesComposite. Different fillersFiller such as egg shell, arhar, graphitic carbon nitrideGraphitic carbon nitride (g-CN) (g-C3N4), and titanium dioxide (TiO2)Titanium dioxide (TiO) were added to epoxy resinEpoxy resin to prepare the variety of compositesComposite. The experiments were carried out on universal testing machine, erosionErosion and pin-on-disc apparatus to assess the mechanicalMechanical and tribologicalTribological behavior, respectively. The influence of parametersParameter such as fiberFiber orientation, fillerFiller sizeSize and content, and fiberFiber volume fractionVolume fraction were discussed. Nano egg shell particulate compositesParticulate composites have shown superior mechanicalMechanical and erosionErosion propertiesProperties when compared to micron particles. The notable breakthroughs in terms of mechanical strengthMechanical strength and erosionErosion resistanceResistance were observed with 2 wt.% activated carbonActivated carbon than 4 wt.% biocharBiochar and 10 wt.% raw arhar fillersFiller. Hybrid polymer compositesHybrid polymer composites with 12 layered bi-directional glass fiberGlass fiber (GF) filled with 2 wt.% g-C3N4Graphitic carbon nitride (g-CN) nano particlesGraphite nano particles have been more beneficial compared to conventional compositesComposite. In contrast to hybrid polymer compositesHybrid polymer composites, novel hybridHybrid sandwich compositesComposite prepared with glass fiberGlass fiber (GF) and TiO2Titanium dioxide (TiO) have shown altered material characteristicsCharacteristics in a single compositeComposite sample as confirmed from erosion wear testErosion wear test.
