The Society of Plastics Engineers (SPE, Bethel, Conn., U.S.) held its 19th annual Automotive Composites Conference & Exhibition (ACCE) in Novi, Michigan, Sept. 4-6. The theme of the conference was “Composites — Forming the Future of Transportation Worldwide,” and much of the programming reflected a growing interest from transportation OEMs in the role composites technologies can play in next-generation mobility.

The conference kicked off with a keynote from Cynthia Flanigan, chief engineer of Vehicle Research & Technology for Ford Motor Co. (Dearborne, Mich., U.S.), who discussed “Driving Automotive Materials Forward.” The keynote speculated about potential changes in the way society uses vehicles.  Global population and overcrowding of urban areas are pushing us toward a need to reshape our modes of transportation and approach mobility in a very different manner than society has in the past. Many theorize that we are moving from a society based on individual vehicle ownership to one where carsharing and e-mobility could represent the lion’s share of the automotive market. Flanigan focused on five key areas that are driving change in the industry: sustainability, emerging materials, additive manufacturing, advanced processes and design, and artificial intelligence.

From reducing ocean plastic and atmospheric CO2 to the use of blockchain technology to link data, track materials and enable sorting and recycling, to looking to nature for inspiration in new materials, Flanigan spoke of sustainability and responsibility to the environment as a key driver of technology trends. She spoke of emerging materials as an enabler for the future, pointing to materials such as graphene and aerogels, contributing to lightweighting and improving the consumer experience through noise dampening. She spoke of advances in additive manufacturing and the technology’s role in the composites space, offering the opportunity for higher throughput and advancements in processing. She summed up the potential of advanced processes, design and artificial intelligence saying, “We at the cusp of [being able] to utilize enabling technologies that are blooming.”

A featured talk from Clay Maranville of Ford Motor Co., echoed many of the ideas from Flanigan’s keynote with a focus on automotive interiors. Maranville looked at megatrends affecting mobility from consumer behavior such as carsharing to such industry trends as additive manufacturing, generative design, embedded sensors, and blockchain. He indicated a shift in design thinking is happening and that automotive interior design is becoming increasingly focused on the consumer experience and the ways that is evolving.

The conference featured a prominent programming track on sustainability, which included 11 papers on topics relating to sustainability. There were numerous presentations on technologies aimed at enabling electric vehicles. Sheet molding compounds (SMCs) aimed at enabling battery systems in electric vehicles were featured heavily at the show. Pritesh Patel of Evonik (Parsippany, N.J., U.S.) discussed an epoxy resin-based SMC battery case for electro-mobility vehicles. Ian Swentak of Hexion (Columbus, Ohio, U.S.) showcased a phenolic resin SMC-based battery box optimized for fire resistance.

Gulay Sherhatkulu, senior vice president, Performance Materials North America, BASF Corp. (Wyandotte, Mich., U.S.) delivered the conference’s second keynote, painting a picture of a new generation of consumers largely comprised of a digital natives who are less concerned with ownership and more concerned with connectivity, comfort, convenience, environmental concerns and sustainability. She spoke of a value chain shifting from a focus on the end consumer to fleet-based transportation companies, and with this fundamental shift, changes is R&D and design thinking, and a need to get products to market more rapidly.

Just how drastically the landscape of automotive sector will change remains to be seen, but it’s clear that the industry is exploring what changing consumer behavior will mean for the future of automotive transportation. Growing populations and traffic congestion indicate that the way we travel as a society will have to evolve. Several ideas bandied about at SPE ACCE revolved around carsharing and included modular component designs to make parts easy to replace, materials with low noise vibration and harshness (NVH), materials with antibacterial qualities — all of which could mean a large role for composite materials.

At the same time, many people see individual car ownership as part of our identity. The final keynote at SPE ACCE was about the composites on the new Chevrolet Corvette Stingray, with its luxury cockpit that wraps the driver in an immersive console. Plenty of composites were employed in the new ‘Vette from primary body structural panels to underbody structural panels to class-A composite body panels to air ducts to its carbon fiber pultruded rear bumper assembly. But the mindset is obviously completely different. For many drivers, a personal connection with the car remains, and it’s a safe bet that carmakers will continue to capitalize on that connection as long as they can.

So, the questions remain. How quickly will large groups of the population transition to carsharing and new solutions for mobility? How many people will cling to their cars? What will the auto industry look like in the coming decades? Only time will tell.
