Automobile bumpers are built to withstand crash forces and shield the car's occupants from harm. They are usually seen at the front and back of a car. Safety grilles, often referred to as grille guards or bull bars, are extra parts that can be attached to the front of a car to provide further security. They are created to safeguard the front of the car and its occupants from harm in the event of a collision with an animal or other obstruction and are normally composed of metal. Plastic, steel, and aluminium are common materials used to make automotive bumpers and safety grilles. Although steel bumpers are strong and can resist a lot of damage, they are also hefty, which might reduce a car's fuel economy. To increase the overall strength and weight of the vehicle, some automakers have begun using cutting-edge materials like carbon fibre in bumpers and grilles. However, even though we are working to create a more environmentally friendly world, using plastic and non-biodegradable products may not be the best solution. The greatest method to improve fuel economy is to lighten vehicle components without compromising safety. The goal of this study is to create a biodegradable composite material that will be utilized to make car bumpers and safety grilles. Although polymer composite materials have been used in the automotive industry for many years, their application has been limited by financial and technical constraints. In this study, a biodegradable composite sandwich construction with a bamboo core and areca fibre lamination was created and bonded using epoxy and hardener. Since impact strength is one of the crucial characteristics of bumpers and safety grilles, the composite structure was manufactured using the vacuum bagging technique and then examined for impact qualities.
