What does “automotive” mean?
The automotive industry is one of the world’s largest and most influential sectors, covering the design, engineering, production, sales, and servicing of motor vehicles. It includes passenger cars, commercial trucks, buses, and specialized vehicles, along with the vast network of suppliers that provide engines, electronics, tires, and thousands of other components. Beyond manufacturing, the industry extends to dealerships, financing, repair, spare parts, and modern mobility services such as leasing and ride-sharing. Since the early 20th century, when mass production and assembly lines first made cars affordable to the public, this industry has been a powerful force in shaping economies, urban development, and social life. Today, it is undergoing major changes through the rise of electric vehicles, digital connectivity, autonomous driving systems, and sustainable manufacturing practices, making it not only a foundation of global trade but also a key driver of innovation for the future of transportation.
The Hydrogen Century: A New Chapter for the Automotive Industry
The automotive world is now stepping into what many describe as the hydrogen century, a period where hydrogen is no longer a distant idea but a practical energy solution. Advances in fuel cell stacks, lightweight storage tanks, and high-pressure refueling technology are transforming hydrogen vehicles from prototypes into market-ready products. Governments across Europe, Asia, and North America are building national hydrogen roadmaps, while leading automakers are committing billions in investment, seeing hydrogen as essential for long-distance travel, heavy-duty trucks, and fleets where battery solutions remain limited. Unlike conventional engines, hydrogen cars emit nothing but water vapor, yet they can be refueled in minutes and driven for hundreds of kilometers, combining the convenience of gasoline with the environmental benefits of electrification. This transition is not only about reducing carbon emissions but also about creating a resilient, diversified energy future that reduces dependence on fossil fuels. Much like aviation’s push into sustainable propulsion, hydrogen mobility signals a profound transformation: a move toward cleaner cities, smarter transport networks, and an industrial ecosystem built around efficiency and responsibility.
The Evolution of Materials in Automotive Manufacturing
Steel Dominance
Automobiles were almost entirely constructed from steel. The introduction of the Ford Model T and the rise of mass production in 1913 cemented stamped steel body panels as the standard for car manufacturing, as strength, durability, and affordability were the top priorities.
First Composite Experiments
Automakers began experimenting with composites. The most famous milestone was the 1953 Chevrolet Corvette, which used fiberglass-reinforced plastic body panels. Although this was a breakthrough, composites remained limited to niche sports cars because of higher costs and limited large-scale production methods.
Lightweight Push with Engineering Plastics
The oil crises and stricter fuel efficiency regulations pushed the industry toward lighter materials. Glass fiber composites became common in bumpers, dashboards, and some body panels, while engineering plastics like polypropylene and polycarbonate were widely adopted in interiors and under-hood parts. At the same time, aluminum began replacing steel in doors, hoods, and engine components, marking the start of multi-material vehicles.
Rise of Mixed-Material Design
Mixed material strategies became mainstream. Automakers combined high-strength steel with aluminum and composites to balance safety, weight, and cost. Luxury brands such as BMW, Mercedes, and Audi began testing carbon fiber reinforced plastics (CFRP) in structural elements, while plastics were widely used in fuel systems, headlights, and air intake systems.
Composites Enter the Mainstream
Composites entered the mainstream, especially with the rise of electric vehicles. Models such as the BMW i3 and Tesla used CFRP, thermoplastic composites, and even natural fiber composites to offset the heavy weight of battery systems. These new materials allowed automakers to achieve both lightweighting and sustainability targets.
Hydrogen & EV Era
The shift toward electric and hydrogen vehicles has accelerated the adoption of composites. Carbon fiber and glass fiber reinforced plastics are now widely used in battery trays, EV platforms, and high-pressure hydrogen storage tanks. Multi-material vehicle platforms are being designed with recyclability and sustainability in mind, while research focuses on lowering costs and scaling up automated composite production.
Future Outlook: 2030s and Beyond
Carbon fiber and thermoplastic composites are expected to rival metals in mass-market cars. With hydrogen storage and EV platforms depending heavily on these materials, and with circular economy models emphasizing recycling and reuse, composites are set to define the future of automotive manufacturing.
Composite Materials Used in the Automotive Industry
Glass Fiber-Reinforced Polymers
GFRP is widely used in body panels, bumpers, and underbody protection. In electric vehicles, it strengthens battery enclosures and skid plates for impact resistance. Durable and cost-effective, it accounts for more than 90% of automotive composites today.
Long Glass Fiber Thermoplastics
LGF/LFTP is applied in structural parts such as enclosures and module separators. In EVs, it is often used for flame-retardant battery covers, delivering over 10% weight savings compared to metal while maintaining strength and safety.
Thermoplastic UD Tapes
Used in hydrogen tanks with EVOH liners to cut gas leakage, these composites also fit EV battery spaces and structural parts. They combine lightweight strength with automated production, supporting cleaner and more efficient mobility.
Thermoplastic Sandwich Panels
Lightweight panels made with honeycomb or foam cores and reinforced skins. They deliver high stiffness with low weight, ideal for EV floors, doors, and trunk structures. Recyclable and easy to process, they help reduce vehicle mass while improving energy efficiency.
EV Thermoplastic Battery Enclosures
Thermoplastics are rapidly replacing metals in battery enclosures as automakers push for lighter, safer, and more sustainable solutions. Using processes like Direct Long-Fiber Thermoplastic (LFT-D), glass or carbon fibers are compounded into polycarbonate or polyamide resins, creating strong yet lightweight parts. Compared to steel, thermoplastic casings cut weight by more than 25% and lower CO₂ emissions by around 30% versus aluminum.
Recent development focuses on:
- High-volume processing: Shorter cycle times allow cost-effective, large-scale EV production.
- Safety performance: Flame retardance, thermal insulation, and electrical isolation built into the material.
- Design flexibility: Thermoplastics enable complex geometries and integration of functions (fasteners, channels, seals).
- Sustainability: Casings now use recycled polycarbonate and halogen-free flame retardants, aligning with green manufacturing.
These advances make thermoplastics not just an alternative to metals, but the preferred choice for next-generation EV and hydrogen battery systems.
The solution jota machinery supply for automotive
Thermoplastic Uni-directional Tape (CFRT)
Thermoplastic UD tapes use aligned, fiberglass, or natural fibers in a thermoplastic matrix, offering exceptional strength with low weight. In cars, they enable 20–40% mass savings, improving fuel efficiency in combustion vehicles and extending range in EVs. They are widely applied in battery enclosures, body panels, and structural reinforcements, while in hydrogen cars they support high-pressure tanks and fuel systems. With fast processing for overmolding and lamination, UD tapes combine performance, recyclability, and cost efficiency—making them a key material for next-generation mobility.
Thermoplastic Sandwich Panels
These composite sandwich panels combine fiber-reinforced thermoplastic skins with lightweight honeycomb or foam cores, delivering excellent stiffness-to-weight performance. In EVs and hydrogen cars, they reduce vehicle mass by up to 50% compared to metals, while providing impact resistance, thermal insulation, and full recyclability. Typical applications include battery enclosures, underbody shields, cargo floors, doors, and interior modules, where they not only improve range and efficiency but also support sustainability goals in large-scale production.
Continuous Fiber Reinforced Technology
Our core expertise lies in continuous fiber reinforced thermoplastic composites, with a strong focus on fiberglass solutions. By combining continuous fibers with advanced thermoplastic matrices, we produce materials that deliver high strength, durability, and impact resistance while remaining lightweight and recyclable. Unlike thermoset composites, CFRTP can be reheated, reshaped, and processed in automated production lines, making it ideal for large-scale manufacturing. These properties make fiberglass CFRTP the preferred choice for next-generation mobility and aerospace applications, from structural panels to safety-critical components, where performance and sustainability must go hand in hand.
Why Fiberglass Matters
Among continuous fiber reinforced thermoplastics, fiberglass is the most practical choice for large-scale automotive use. It offers the right balance of strength, weight reduction, and cost efficiency, making it more accessible than carbon fiber while still meeting structural demands. Fiberglass also works efficiently with thermoplastics, allowing fast cycle times, automated production, and recyclability—advantages critical for modern vehicle platforms. By focusing on fiberglass CFRTP, we deliver lightweight, scalable, and sustainable solutions that meet the performance and cost requirements of next-generation mobility.
How We Manufacture
We specialize in automotive thermoplastic composite processes including impregnation, unidirectional (UD) tape production, and double belt pressing. Impregnation ensures consistent resin distribution and fiber wet-out, producing high-quality prepregs. UD tapes provide rapid processing, recyclability, and compatibility with automated production. Double belt pressing enables continuous consolidation with precise thickness control and surface finish. Together, these processes create lightweight, durable, and scalable materials that support vehicle weight reduction, safety, and sustainability for future mobility.
