Thermoplastic composites incorporated into vehicle seatback concept

Covestro’s Maezio carbon fiber-reinforced thermoplastic composites were used to develop a lightweight, sustainable seatback concept for a Chinese car manufacturer.

Covestro (Leverkusen, Germany) announced on Jan. 14 that it has partnered with the Research and Development Center of Guangzhou Automobile Group Co. Ltd. (GAC R&D Center; Guangzhou, China) to develop a lightweight composite seat back for the car manufacturer’s latest electric concept car, the ENO.146.

The ENO.146 is designed to be a highly aerodynamically efficient vehicle, with a drag coefficient of only 0.146 and a New European Driving Cycle (NEDC) range of 1,000 kilometers. Efforts to reduce vehicle weight and increase sustainability have resulted in the selection of Covestro’s Maezio carbon fiber-reinforced thermoplastic composite (CFRTP) material for the backrests of the concept car’s front seats. Compared to typical metal constructions, the CFRTP seat backrest results in estimated weight savings of up to 50%.

“Seats in the passenger compartment are an ideal target for weight savings, as they are among the heaviest parts there,” says Lisa Ketelsen, head of Covestro’s thermoplastic composites business. “Fiber-reinforced composites are the ideal material for lightweight automotive construction, but Maezio can further simplify molding and streamline the manufacturing process.”

According to Covestro, fittings and other attachments add to the complexity of production and assembly for seats with metal backrests. Because Maezio is a thermoplastic material, parts and functions can be consolidated by injection molding processing. Functional structures are incorporated into the mold for shaping the backrest, reducing the number of parts and materials.

The backrest also needed to meet the aesthetic and sustainability goals of the vehicle interior, which was designed with green colors and patterns reminiscent of nature and to incorporate sustainable or recyclable materials. The Maezio material is able to be cut and shaped into the desired marble-like pattern, fitting aesthetic requirements, and can be reused at the end of its service life, which suited the team’s sustainability needs.

“Mobility trends such as electrification and autonomous driving are redefining the role and function of car interiors,” says Zhang Fan, vice president of the GAC R&D Center. “There is a growing need for material solutions that are lightweight and sustainable while opening up ways to create new user experiences ranging from visual to tactile feedback.”

The vehicle recently made its debut at the Guangzhou International Automobile Exhibition.

Evonik (Parsippany, N.J., U.S.) announced on Jan. 7 that its Crosslinkers Business Line has received award recognition from the International GREEN Auto Lightweight Technology Alliance (IALTA) for its VESTALITE S epoxy hardener for use with sheet molding compounds (SMC).

With the annual Automotive Lightweight Green Technology Award, IALTA recognizes technologically innovative companies that have made outstanding contributions to the development of innovative international automotive lightweight and green technology applications. The award recognizes technologies that are significantly beneficial for vehicle energy-saving, emission-reduction and safety as well as the application of lightweight vehicle material. The 2019 award was presented to Evonik at an event in Hefei, China in December 2019.

Evonik’s VESTALITE S curing agents have been developed for use with epoxy SMC materials in automotive applications, designed to meet increasingly stringent requirements for both lightweight design and vehicle indoor air quality. VESTALITE S is said to improve the technical properties and workability of high-performance SMCs for use in e-mobility applications and automotive lightweight construction.

“VESTALITE S curing agents in combination with epoxy resins result in SMC materials that are quick and easy to process for structural lightweight applications with minimal emission values,” says Dr.-Ing. Leif Ickert, who is responsible for marketing of composites and adhesives in Evonik’s Crosslinkers business line.

ITHEC 2020 call for papers by Feb. 15

Premier  thermoplastic composites conference features enlarged exhibition and new  Advanced Thermoplastic Composite 3D Printing Forum, powered by CompositesWorld.

ITHEC 2020 5th International Conference & Exhibition on Thermoplastic Composites

ITHEC 2020, 5th International Conference and Exhibition on Thermoplastic Composites, October 13-14 in Bremen, Germany is accepting abstracts regarding cutting-edge topics in thermoplastic composites by February 15.  The organizers request a one-page abstract from engineers, scientists and industry experts working in the field of high-performance thermoplastic composites, as well as related manufacturing technologies and applications.

SGL Carbon (Weisbaden, Germany) reported on Jan. 20 that it will begin serial production of air taxi landing gear made from braided carbon fiber material early next year. The landing skids will be installed in around 500 air taxis worldwide over the next two years, the company says.

The 2-meter-wide by 1.5-meter-wide ultra-light landing skids will weigh less than 3 kilograms, making them about 15% lighter than a similar component made from aluminum. SGL Carbon says lightweighting is particularly important for increasing potential flight time capacity of the electric motor-powered air taxis.

The landing gear was developed in collaboration with customer experts and specialists from SGL Carbon. The carbon fibers for the component are produced at the SGL Carbon plant in Muir of Ord, Scotland. The final part is being manufactured at the SGL Carbon site in Innkreis, Austria.

“With with our landing gear, we help to shape this very new, promising application of manned, autonomous civil aviation. This involvement also demonstrates our wide range of services. From engineering, to prototype manufacture, to serial production with our own materials — all of our competences along the entire value chain made a contribution to the project,” says Dr. Andreas Erber, head of the aerospace segment of the Composites — Fibers & Materials business unit at SGL Carbon.
