The global automotive composite leaf spring is a niche market and currently represents less than 1% of the total automotive leaf springs (metals + composites) market. It is likely to remain niche in the foreseeable future but possesses significant growth potential in the coming years. It is forecasted to grow at an attractive rate over the next five years to reach US$ 86.6 million in 2023. Increasing automobile production, an increasing demand for lightweight leaf springs to achieve stringent government regulations of many countries, such as CAFÉ Standards, and the market entry of new players targeting local markets are the major factors that are proliferating the growth of the composite leaf springs market in the automotive industry.
Composite leaf springs are not new to the automotive industry. Chevrolet Corvette has been using composite leaf springs on both front and rear locations at the transversal position since 1981. Composite leaf springs offer several benefits over steel leaf springs, such as high durability, greater flexibility, better vibration energy absorption, and fatigue resistance. Composite leaf spring is about five times more durable than similarly-sized steel leaf springs. The biggest advantage of composite leaf spring is its significant weight savings. It is about 1/7th the weight of a steel leaf spring.
