Low Density Polyethylene/Polymeric Microballon Syntactic Foam: Strain Rate Dependent Compressive Response

Syntactic foams of five different densities were prepared with low density polyethylene (LDPE) matrix and polymer micro-balloons at five different concentrations. The prepared samples were subjected to compressive loading at different strain rates. The compressive strength of the foam material is decreased with increase in weight percentage of polymer micro-balloon filler material in it. The compressive strength of foam is found to be better at higher strain rates when compared to samples tested at lower strain rates.
