Role of Zirconia Filler on Mechanical Properties and Dry Sliding Wear Behavior of Glass/Basalt Hybrid Fabric Reinforced Epoxy Composites

Abstract:

This paper presents the effect of zirconia filler on mechanical properties and dry sliding wear of bidirectional hybrid (glass and basalt fiber) fabric reinforced epoxy (G-B/E) composites. Fabrication was done by hand layup method followed by compression molding. The effect of zirconia filler loading on mechanical characteristics like hardness, tensile and flexure of fabricated G-B/E composites were determined according to ASTM standards. Also, wear behavior under dry sliding condition was performed using pin-on-disc machine for different applied normal loads/sliding distance. Experimental results reveal that incorporation of zirconia filler improves the mechanical properties. Further, the wear test results indicated addition of zirconia into G-B/E hybrid fiber composites plays important role on specific wear rate under the tribo-conditions selected for the study. Further, inclusion of zirconia into G-B/E composites shows improved wear resistance and addition of 6 wt. % of zirconia exhibits least specific wear rate compared to other hybrid G-B/E composites. In addition, Scanning electron microscope images of selected mechanical test fractured coupons also have been discussed.
