Abstract
Syntactic foams are porous particulate composites fabricated by mixing hollow particles called micro-balloons into a matrix material such as metal, polymer, ceramic etc. Fillers i.e. micro balloons are used to decrease the amount of expensive matrix material and/or to enhance or tailor some properties of matrix materials. The different variations in density and properties of syntactic foam could be obtained by changing the material, volume fraction and/ or density of micro balloons. Here the hybrid syntactic foams were synthesized by adding two different filler materials that are hollow glass microballoons and flyash cenospheres into vinyl ester matrix. Two types of hybrid systems are created one with 50% total filler content and another with 60% total filler content in a matrix whereas, within these hybrid systems an internal composition of two fillers were varied in a step of 25 vol% with respect to each other. Hybridization of two different types of ceramic microballoons in vinyl ester matrix gives maximum 111% increase in impact strength with respect to plane hollow glass microsphere syntactic foam. Hybridization also causes lncrease in flexural strength and Flexural modulus by 39% and 58% respectively.
