Biodegradability and recyclability compel the researchers as well as engineers to explore for new material advancement. In this work, fly ash, a residual material from thermal power plants is utilized as reinforcement. Hybrid polymer, a mixture of natural and synthetic polymers, is utilized as matrix. The impacts of type of synthetic resins, percentage of natural polymers and percentage of fly ash on tensile behavior of fly ash reinforced hybrid polymer matrix composite are studied. Isophthalic polyester resin, General purpose resin and Vinyl ester are used as synthetic resins. Cashew nut shell resin (CNSL) is the natural polymer employed as a part of this work. Design of experiments (DOE) notion i.e. Taguchi orthogonal L9 array is selected to carry out the fabrication of specimens. Then the developed specimens are tested for investigating its tensile behaviors in regard to its various constituents using INSTRON. ANOVA technique is implied to find the level of influence of various parameters on tensile behavior of composites. © 2017 Elsevier Ltd.
