Abstract

Automotive front-end modules (FEMs) typically are multipieces assemblies that integrate a large number of components like: Engine Compartment, forward lighting, radiators and cooling fans, air conditioning (A/C) condensers, grille-opening reinforcement (GOR) panels, crumple zones, bumpers with decorative fascia, hood latches, washer bottles, plus electronics and wiring. Front End Module component consists of mainly four parts. They are: Frame, Polyamide Ribs, Front End Module Bracket, Z-Braces. The function of the frame is to carry the load coming from the hood latch. In the series, Frame is made of steel, since model weight is a major factor for such a huge component which also comes close to the engine compartment. It is highly recommended to optimize the frequency of Front Module by reducing the weight. Hence the project emphasize majorly on weight optimization of Front End Module assembly. Based on this fact, a proposal is made on changing the material of Front End Module Frame with composite. In this project frame of the Front End Module is made by carbon fiber reinforcement laminated composite. It is subjected to linear static analysis using ABAQUS solver software. From the results it is shown that frame made by laminated composite has 62 % reduction in mass when compared to steel. Also it is shown that the strength of frame made by steel and laminated composite is almost equal for 2KN load case and for 5KN load case there is drastic rise in strength of frame made by laminated composite. It is observed that carbon fiber material is the best replacement material for frame in terms of stiffness and mass only if cost is not a major issue.
