Market Dynamics

Market Drivers

Increasing Demand for Fuel Efficiency and Emission Reduction

The push towards greater fuel efficiency and reduced emissions is a significant driver in the global market. Governments worldwide have implemented stringent regulations aimed at reducing the carbon footprint of vehicles, which in turn necessitates the adoption of lightweight materials to improve fuel economy. For instance, the Corporate Average Fuel Efficiency (CAFE) regulations in the United States mandate that automakers attain a fleet-wide average fuel efficiency of 54.5 miles per gallon by 2025.

Similarly, the European Union's regulations mandate reducing CO2 emissions for new cars to 95 grams per kilometer by 2021. These regulations are driving the demand for materials such as high-strength steel, aluminum, and carbon fiber composites, which can significantly reduce vehicle weight and enhance fuel efficiency.

Market Restraint

High Manufacturing Cost of Automotive Lightweight Materials and High Waste Generation

Despite several benefits of lightweight materials, such as enhanced fuel efficiency and reduced emissions, the demand for these materials is still expected to be restrained by the high manufacturing costs. Another problem with alternative material solutions is the high amount of waste generation. At the end of its life, steel can be extracted from cars, which can be further recycled and reused to make another car or some other steel product without compromising its strength. However, in the case of alternative materials, especially carbon fiber-based materials, recycled material cannot be used for making other cars due to decreased strength. They need to be treated before being used in other products, thus further leading to a higher cost.

Market Opportunities

Advancements in Manufacturing Technologies

In response to the rising demand for vehicles with innovative designs and features, advanced manufacturing technologies are substituting conventional manufacturing techniques. These technologies include resin transfer molding, additive manufacturing, and microinjection molding. The primary benefit of incorporating such advanced manufacturing techniques is the ability to produce comparatively lighter and stronger materials. Moreover, these advanced manufacturing technologies are intended to operate with little to no material waste.

For example, additive manufacturing technology results in comparatively little material waste. The development of carbon fiber, which has one of the highest weight-to-strength ratios, has been substantially aided by this manufacturing technology. This technology is also compatible with varying plastics, composites, and metal grades. With the 2020 Model 18 Roadster sports car, BMW (Germany) has demonstrated its additive manufacturing capabilities. These innovative processes and technologies assist the automotive industry in meeting the growing demand for lightweight materials, thereby creating opportunities for market growth.
