Abstract: Manufacturing and evolution of complimentary operated engineering materials from unwanted substances has gained worldwide engrossment. The materials made from bio waste can able to get over the synthetic material due to their isolated properties like inexpensive, non-toxic, nonabrasive, biodegradable, pollution emission free and ecofriendly. The Calcium Carbonate rich egg Shell causes serious environment hazards. Effort has been made to incorporate these bio waste egg shell materials into the matrix which form composites to boost up the mechanical properties. So the objective of this study is to make composites which should have a good compressive strength as well as low density. Most of the researchers emphasizes towards the making of light weight material which are significant to automobile, aerospace, electronics industries. Now special care has been increased gradually in the composite industries to make it greater potentiality of application in the field of medicines, chemical industries, and marine and also for household things. Keeping these requirements into mind, the present investigation is mainly focused on the mechanical properties of egg shell reinforced composites. Chicken egg shell were collected, washed with deionized water to remove the inner layer membrane, then dried and powdered. X-ray diffractometry (XRD) and Field Emission Scanning Electron Microscopy (FESEM) were used to characterize the crystalline size, constituent compounds and surface morphology respectively. The internal adhesion between the surface of reinforcement and matrix (Lapox) was enhanced by doing the chemical treatment of egg cell with NaOH solution. The composites were made by hand layout technique. Three sets of modified (NaOH treated) and unmodified (Raw) samples were prepared for the flexural tests. Result shows the enhancement of mechanical properties with increase in NaOH concentration.
