    Abstract
    Current foam materials do not meet the requirements for high performance. Minimal research has been done on thermoplastic polyurethane (TPU) foams fabricated by non-synthesis approach. In this study, Hollow GlassMicrospheres (HGMS) reinforced TPU foamwas fabricated by compression molding using TPU polymer. Interfacial adhesion between the filler and the matrix was enhanced by surface modification of the HGMS. The morphology of fabricated foam was studied using Scanning Electron Microscope (SEM). Density, hardness and mechanical tests were done to study the foam properties. Increasing the foaming agent content from 1% to 2% led to a decrease in tensile strength of the foam by about 50%. The tensile strength decreased by about 40% when the filler content was increased from 0% to 3%, while the compressive strength of the composite foam increased by about 47% when the filler content was increased from 0% to 7%. Increasing filler content led to a decrease in the density and increase in hardness of the foam. After a 75% compressive force, SEM observation of 7% HGMS reinforced TPU foam had a more stable structure than 5% HGMS reinforced foam which depicts enhancement in mechanical properties, a property desired for high impact absorption applications.
