Automotive Lightweighting: An Overview of Techniques and Materials

Automotive lightweighting involves integrating lightweight structural design and manufacturing technologies with various lightweight materials to reduce the overall mass of vehicles.

This reduction is achieved while ensuring vehicle usability, safety performance, and cost control.

The goal is to improve vehicle dynamics, reduce fuel consumption, and lower exhaust emissions.

Research indicates that reducing a vehicle’s weight by 10% can improve fuel efficiency by 6-8%, and every 100 kg reduction can lower fuel consumption by 0.3-0.6 liters per 100 km and CO2 emissions by 5 grams per km.

Therefore, driven by environmental and energy-saving needs, automotive lightweighting has become a global trend, with the use of lightweight materials being the primary direction for development.

High-performance fiber composites and thermoplastic elastomers (TPE) are key materials widely used in this field, showing significant promise for future development.

Carbon Fiber: A Key Material for Automotive Lightweighting

Carbon fiber, with a carbon content of over 90%, is a fibrous carbon material with a density less than one-quarter that of steel but with a tensile strength 7-9 times greater.

It retains excellent properties, such as light weight, high strength, strong design flexibility, high damping, high-temperature resistance, corrosion resistance, and impact resistance, even in inert environments at 2000°C.

Major automotive manufacturers have been leaders and promoters of carbon fiber reinforced polymer (CFRP) for lightweighting.

Replacing traditional metal materials with CFRP can reduce the weight of car chassis and bodies by 40%-60%.

Initially used in high-end sports cars like Lamborghini and Ferrari, CFRP applications have expanded to high-end sedans such as BMW and Mercedes-Benz and will continue to extend to regular sedans and large buses.

All-carbon fiber wheels and carbon fiber rims with alloy spokes are 35% and 25% lighter than forged alloy wheels, respectively, significantly reducing the vehicle’s overall weight.

CFRP brake discs exhibit excellent braking stability, reducing vehicle speed from 300 km/h to 50 km/h within 50 meters without being affected by the brake disc temperature rising sharply to 900°C during the process.

BMW is a pioneer in applying CFRP in the automotive field, leading the way in its full-scale application in car bodies, interiors, and exteriors.

Other manufacturers like Toyota, Mercedes-Benz, and Hyundai have also adopted CFRP in various car components, including bodies, chassis, wheels, and roofs.

Benefiting from national strategic planning and policy support, numerous Chinese enterprises have also undertaken research on carbon fiber applications for automotive lightweighting.

Glass Fiber Reinforced Plastics: A Versatile Lightweight Material

Glass fiber reinforced plastics (GRP), with thermoplastic or thermosetting resins as the matrix, are lightweight, high-strength, heat-insulating, sound-insulating, waterproof, easy to color, and easy to mold.

These properties make GRP suitable for manufacturing car bodies and various parts for sedans, buses, and trucks, achieving weight reduction and improved vehicle weight utilization.

Developed countries in Europe, America, and Japan extensively use SMC composites in all types of vehicles, including suspension parts, bodies, and interior components, with the highest usage in bumpers, roofs, front-end modules, hoods, and acoustic panels.

The urgent need for lightweight, recyclable, and easily processed materials in the automotive industry has driven the market share of glass fiber reinforced thermoplastic composites (GMT), primarily used in bumpers, to grow continuously.

Natural Fibers: Eco-Friendly and Renewable Materials

Natural fibers like bamboo, hemp, wood, and cotton have environmental friendliness and renewability advantages.

Bamboo fiber reinforced composites combine light weight, high strength, and high rigidity.

Car interior panels made from bamboo fibers are less prone to damage in accidents due to bamboo’s unique toughness, reducing the product weight by 20%.

Wood-plastic composites (WPC) using hemp and flax fibers as reinforcement in polymers can be molded or injection-molded into car parts like doors and seats.

Strengthening natural fiber components with reinforcements can produce seat frames, armrests, dashboards, hoods, side collision protection parts, and chassis components.

Synthetic Fibers: Meeting Modern Automotive Demands

Synthetic fibers such as polyester, nylon, aramid, acrylic, and spandex meet modern automotive demands for safety, comfort, durability, and stability.

These fibers have excellent strength, color fastness, breathability, flame resistance, moisture absorption, pilling resistance, and antistatic properties, making them widely used in automotive interiors like seat fabrics, seat belts, and airbags.

Thermoplastic Elastomers (TPE): Accelerating Lightweighting

Thermoplastic elastomers (TPE) combine the plasticity of plastics and the elasticity of rubber, offering recyclability, good mechanical properties, easy processing, and excellent weather and aging resistance.

TPE materials have rapidly replaced traditional rubber materials in the automotive industry since the 1990s due to their weight reduction capabilities, improved part performance, and enhanced recycling rates.

The growing demand for automotive lightweighting and stricter global fuel economy standards have significantly driven TPE demand, with a projected average annual growth rate of 5.5% over the next five years.

TPE Varieties and Applications

– Styrenic Block Copolymers (SBCs): The most produced and rapidly developing TPE, SBCs have excellent ozone, oxidation, UV, and weather resistance, comparable to EPDM rubber for non-dynamic applications, used in seals, shift knobs, brake handles, and trim.

– Thermoplastic Polyolefin Elastomers (TPO) and Thermoplastic Vulcanizates (TPV): Composed of rubber and polyolefins, TPO/TPV are primarily used in automotive parts for their impact resistance, water, acid, and alkali resistance, meeting diverse product requirements through extrusion, co-extrusion, injection molding, etc. Applications include windshield seals, window seals, glass guides, wiper strips, headlight seals, fuel tank caps, air ducts, fuel hose guards, and electrical wire covers.

– Thermoplastic Polyurethane (TPU): A block copolymer with high mechanical strength, wide hardness range, excellent vibration damping, strong adhesion, sound insulation, wear resistance, oil resistance, water resistance, flexibility, and aging resistance. TPUs are used in tires, seats, headrests, floor mats, dashboards, sun visors, door panels, shift lever knobs, vibration pads, bushings, airbags, and seals.

– Thermoplastic Polyester Elastomer (TPEE): A linear block copolymer with high mechanical strength, fatigue resistance, oil resistance, and weather resistance, but poor hot water resistance. TPEE is used in intake hoses, steering dust covers, airbags, seals, gears, belts, oil hoses, safety belt components, headlights, door locks, satellite antenna clips, and door handle seals.

Conclusion

High-performance fiber composites and thermoplastic elastomers, with their excellent properties, provide crucial material support for automotive component manufacturing, significantly advancing the process of automotive lightweighting.

Continuous global development and improvement of lightweight materials will further reduce vehicle system costs, lessen mass, enhance component performance, and increase recycling rates, paving the way for a bright future in automotive lightweighting.
