With the increasing need for developing fuel-efficient and high-performance vehicles, light weighting has become a very important aspect in automotive industry. Hence conversion of the existing metal components to composites is gaining momentum. Composite materials are much lighter than metals and offer many advantages such as fuel efficiency, corrosion resistance and improved life which has resulted in the increased usage of composite materials. Front under-run protection device (FUPD) is a protective device which is fitted on the front side of a truck which prevents the vehicle in front from under-running below the truck and also absorbs impact energy in case of a collision. This paper discusses the design, development and certification from ARAI of the lightweight composite front under-run protection device (FUPD). It has resulted in 33.33% weight reduction compared to the earlier metal component.

The current battery carrier for commercial vehicles is made of steel and is designed to hold two batteries weighing approximately 80 kg to 100 kg. However, this battery carrier faces several issues including corrosion, chemical reactivity, high maintenance requirements and its heavy weight. To tackle these challenges, a fiber-reinforced composite battery carrier is designed and developed specifically for commercial vehicles. The objective is to identify a solution that can meet the performance requirements of both static and dynamic loading, thereby reducing the overall weight. The proposed composite battery carrier offers a lightweight design, requires minimal maintenance, possesses high tensile strength and stiffness and is corrosion and chemical resistant. Furthermore, it provides the flexibility to integrate battery cover locking arrangements for added convenience and security.
