This work involves the study of the thermal, mechanical and physical properties of epoxy filled with nanoegg shell particles. Nanoegg shell particles of near uniform size and shape were prepared by high-speed ball milling technique. The influence of nanoegg shell particle concentration (1 to 5 wt.%) on epoxy curing rate, thermal stability, dynamic mechanical properties and the tensile, hardness, impact and water uptake properties was evaluated. The result showed improvement in most of these properties except for storage modulus in the rubbery phase. Microscopic examination revealed strong particle–matrix adhesion strength, with optimum improvement of all properties at 2 wt.% nanoegg shell filler concentration.
