Deformation and fracture behavior of treated fly ash-filled polycarbonate-toughened epoxy resin composites

Thermoset/thermoplastic blends, namely diglycidyl ether of bisphenol A/polycarbonate (epoxy/PC) system, with different weight percentages of PC, were cured using aliphatic curing agent triethylene tetramine (TETA) and mechanical properties of the cured resin were studied. Further, series of silane coupling agent treated fly ash in 6 wt% PC/epoxy resin blend matrix cured with TETA were prepared by hand lay-up method. Variation in deformation behavior in the form of mechanical properties namely, tensile, flexural, compression, and impact behaviors with filler content was evaluated. Fractographic study of blends and composites using SEM was investigated
