Teijin's carbon fiber-reinforced thermoplastic for electric wheelchair
WHILL Inc., a global leader in inclusive mobility technology, has selected Sereebo P CFP series, a carbon fiber-reinforced thermoplastic (CFRTP) material from Teijin Limited, for key structural components of the upcoming WHILL Model C Lite.

Suitable for high-flow injection molding
Sereebo P CFP series is available as a pellet and can be injection molded with standard machines. It offers high flow during molding for producing thin and complex shapes, including the foot support, back support, armrests and battery case of the Model C Lite.
Compared to traditional aluminum and magnesium, injection-molded Sereebo P CFP series reduces weight and manufacturing costs and complexity.
Because WHILL creates sophisticated, user-friendly designs that blend naturally into everyday life without appearing bulky or intimidating, injection molding was the most suitable method to achieve a high level of design flexibility.
High strength, light weight, and sustainable option
Sereebo P CFP series provides high strength, light weight, design flexibility and system cost advantages to the Model C Lite, which is a battery powered, single-seat, last-mile device. This new model combines maneuverability with light weight and one-handed folding to ensure ease of handling and operation.
Sereebo series, which is derived from “Save the Earth, Revolutionary & Evolutionary Carbon”, also features light weight and durability. Sereebo P CFP series is made from post-industrial recycle (PIR) carbon fiber, which is uniformly dispersed in a polyamide resin.
Expanding application to wider industry range
Based on its customer-centric business model, Teijin will continue to supply composite materials, including Sereebo series, to the mobility sector.
At the same time, the Company is working on applications in a wide range of other industries that require light weight, strength and design innovation, such as drone and robotic parts, as well as other electrical and electronic components and equipment.
