A Review on Design and Analysis of Composite Leaf Spring Using Various Composites

Leaf spring is one of the most critical ingredients in an automobile. Which is using in the suspension system, as it constitutes 10-20% of the weight of the vehicles, specifically the unsprung weight. Thus, leaf spring is one of the possible parts for weight reduction in the automobile. So the global an automobile manufacturer has shown increased interest in the competition to design optimization and improved manufacturing processes. Reduction in automobile weight can be achieved by using design optimization, better composite material and optimized manufacturing processes. In this review paper, the emphasis was focus on the studies and research carried out on the leaf spring in the vehicle that aims to reduce weight and cost in the automobile manufacturing, put in this study according to the years of publication as reference for the researchers and for designers interested in this field.
