Design and analysis of composite materials based piston

Abstract

For decades, the piston has been designed to impart force to the crank shaft via a piston rod by expanding gases in the cylinder. During operation, the piston must withstand cyclic gas pressure and inertial stresses, resulting in fatigue damages such as piston head cracks, piston side wear and so on. Because of their small weight and high heat transfer rate, olden pistons were composed of C.I or aluminum. Following various studies, it was discovered that when cast iron is heated, it expands and covers the clearance level, causing the engine to seize. The mechanical and thermal properties of the piston are described in this paper when the study is conducted using five distinct methods.
