Abstract:For
the past few decades, there has been a rapidprogress in the field ofmaterial science which has resulted in the reduction of cost and weight of materials. This modified systems developed by incorporating various advanced and smarter materialshas led to areduction in number of accidents andtherefore, the safety has increased, which again has been an utmost concern for any industry in modern times. The present work is an attempt to provide the readers with a comparative overview in the context of conventional and advanced materials focusing on a mechanical joint, i.e. the Knuckle joint. A Knuckle joint finds its extensive application for connecting two rods subjected to normal tensile load and requiring flexibility in its angular movements. Here, we are suggesting a modification over theconventionally used material, such as Aluminium alloythat is widely used for manufacturing the Knuckle joints.The results obtained from our study approves that the use of composite material not only decreases the weight of the material but it also improves the life of the component as the composite material shows less deformation in comparison to the conventional one. In the present work, CATIA V5R18 has been used for modellingthe 3D geometry of Knuckle Joint and ANSYS (Workbench 16.2) is been used for

finite element analysis of the same with the conventional and composites materials respectively. Composite analysis is based on Rule of mixtures. Keywords:Knuckle Joint, CATIA V5R18, ANSYS 16.2, FEM, Carbon FiberAluminum. 1.
INTRODUCTION
Knuckle Joint is a mechanical part which is used to connect two rods under tensile load when there is a requirement of asmall amount of flexibility, or angular moment is necessary. The line of action of theload is always axial or linear [1]. The axes of these two rods either coincide or intersect and lie in one plane. A knuckle joint is unsuitable to connect two rotating shafts, which transmit torque [2]. Knuckle Joint is named so because it is free to rotate about the axis of a knuckle pin.A typical knuckle joint has the following parts namely [3]. 1) Fork end 2) Eye end 3) Knuckle pin 4) Collar 5) Taper pin
