------------------------------------------------------------------***--------------------------------------------------------------------A bumper is typically manufactured from steel, Aluminum, Abstract – A Front Bumper beam is an important automotive component to protect passengers from injury and damage produced by severe collision. Composite materials can be used in Bumper beam to increase the structural performance and providing light weight solutions. Initially we considered 3 shapes of bumper beam i.e., D shape, B shape and C shape. Static Structural analysis was performed on these 3 shapes. The results are analyzed from the aspect of Equivalent stress and Total deformation. Then it is observed that C shape bumper beam gives better best result than other shapes. So, we used C shape bumper for further process. For designing of bumper beam 2 different composite materials are used i.e., jute fiber and synthetic glass fiber. Static structural analysis performed for both the composites. After FEA results, Optimized composite beams manufactured using hand lay-up method. Experimental validation of optimized composite beam was done on Universal Testing Machine by three-point bending test.
etc. It absorbs shocks from automotive accidents. The standard says it needs protection within the region sixteen to twenty inches higher than the paved surface.
Key Words:
As electrical cars are chiefly specialized in the efficiency of the battery and driving range. So, scale back the burden of the automobile is best plan to extend the potency of the electron volt. So, to beat this designated Al and stuff are designated to develop machine bumper. however, focus is on conjointly strength of the bumper. Develop differing kinds of form of bumper to extend the effectiveness of the most purpose of bumper.

1. INTRODUCTION In recent years the auto industries are principally concentrating on electrical cars development. however electrical automotives conjointly needed external body to protect passengers from car accident. And conjointly want BIW systems for assemblies [2]. The Bumper is most vital element and highlighted part in safety. The bumper is generally manufactured from steel.
There are differing kinds of stuff on the market in market and chiefly classified as natural stuff and artificial composite materials [1]. These constituent materials have notably dissimilar chemical or physical properties and are incorporated to form a cloth with properties in contrast to the individual parts. Inside the finished structure, the individual parts stay separate and distinct, characteristic composites from mixtures and solid solutions. Fiber- reinforced chemical compounds embrace carbon fiber bolstered polymer and glassreinforced plastic. If classified by matrix then there are thermoplastic composites, short fiber thermoplastics, long fiber thermoplastics or long fiber- reinforced thermoplastics.
A bumper may be a structurally connected or integrated with the front and rear ends of a motorized vehicle, to soak up the impact in a minor collision, ideally minimizing the repair prices. the aim of getting a bumper on your automotive is incredibly specific. many of us suppose that its purpose is to stop or reduce injury severity in a very crash [3]. In fact, bumpers don't seem to be thought of safety options supposed to shield occupants in the slightest degree. The aim of bumper is to scale back or forestall physical harm to the front and rear of vehicles in low-speed crashes. The bumpers are designed to shield the hood, trunk, grill, fuel, exhaust and cooling system.
