Improvement of some mechanical properties of epoxy using uncarbonized and carbonized eggshell powder

Abstract

During the previous years, utilization of natural bio-fruit waste has received way more attention than ever before, this because the low cost of bio-fibers and to improvement some properties of polymer composite and also to reduce the environmental west. Egg shell powder, with grain size (100μm) was added with 5,10,15,20 and 25% weight fraction to epoxy to improve some mechanical properties like: hardness, impact, compression, tensile and bending.
