Abstract

                      This paper gives synopsis of the results obtained when conventional composite materials are replaced with the modern composite materials such as KEVLAR® composite materials in the manufacturing of automobile engine transmission box parts such as engine connecting rod, crank shaft, main shaft, lay shaft, gear wheels, dog clutches and cylinder casing, etc. The main intent for the replacement of material is to reduce the wear rate and frictional losses of engine during power transmission and to get the maximum torque output from the engine. In this article the main shaft manufacturing material (usually chrome steel, nickel chromal, forged steel, high speed steel etc.) is replaced with different Kevlar composites (Kevlar 29,Kevlar 49, Kevlar149). Fir this the main shaft is designed by using reverse engineering in Professional Engineer (PRO-E) and its analysis with the mentioned materials is done in solid works.
