Evaluation of Mechanical Properties of Polyamide-Egg Shell Powder Composite Materials

Abstract

A composite is a structural material which consists of two or more constituents. The constituents are combined at a macroscopic level and are not soluble in each other. One constituent is called the Reinforcing Phase and the one in which it is embedded is called the Matrix Phase. The reinforcing material may be in the form of fibers, particles or flakes. The matrix phase materials are generally continuous. Fibers are used to carry the load and matrix is used to bind and transmit the load to fibers. Fibers can be produced with various materials, such as metals, glass and plastics etc.  Now a day's natural fibers like animal feathers, plant fibers are used to produce the composites.

In the present work polyamide is used as a matrix materials, the egg shell particles are used as reinforced material to produce the composites. The mechanical properties such as tensile strength, impact strength, flexural strengths have to be tested.
