تحضير متراكبات من الأيبوكسي و مسحوق قشور البيض لاستعمالها في طلاء السطوح

Abstract EN

In this work , impact strength and the water absorption ratio of powders of white and brown local chicken eggshell reinforced epoxy with different volume fractions ( 1 , 2 , 3 , 4 and 5 % ) were studied .

The experimental results show that composite filled by ( 1 % Vol .

)of white eggshell powder exhibited maximum impact strength and high resistance to tape water , so we choose this volume fraction to use the epoxy composite in coating .

Optical microscopic observations are taken to develop a better understanding of the phenomena taking place in the material system at microscopic level .
