Weight Reduction


Toray is helping automobile manufacturers achieve significant reductions in vehicle
weight by replacing metal with light, strong, carbon fiber composites
and flexible, moldable, engineering plastics.
With decades of experience in the field, Toray solutions are helping the industry reduce CO2 emissions and
develop next-generation electric and fuel cell vehicles for a sustainable, low-carbon future.

With more than 10 times the strength of steel and only about one-quarter of its weight, carbon fiber composites make it possible to reduce vehicle weight dramatically.
Toray's carbon fiber fabrication technologies are continuously evolving, enabling composites to be used for an ever-expanding range of applications.

Specific weight 1/4 for iron, Strength x10 for iron

Toray's advanced Hi-Cycle Resin Transfer Molding (RTM) process uses high-speed injection and ultra high-speed thermosetting technologies to significantly reduce the time required for Carbon Fiber Reinforced Plastic (CFRP) component production.


Toray's Smooth Resin Transfer Molding process is used to produce rooftop panels and other components with high strength, superior airflow characteristics, and an ultra-smooth finish that simplifies component finishing and coating.


Combining carbon fibers and engineering plastics with metals such as steel and aluminum, Toray continues to develop an ever-expanding range of composites for the automobile industry.

Toray TORELINA® PPS is a lightweight super engineering thermoplastic that can reduce vehicle weight significantly. Offering excellent dimensional stability and resistance to heat and chemicals, it can be used as a replacement for metal in engine cooling modules, ignition coils, and other components that require high heat and corrosion resistance.

PPS resin

Toray AMILAN® nylon resin nylon resin is an engineering plastic that offers excellent rigidity and resistance to heat and oils. It can be used to manufacture a variety of parts, including intake manifolds that are approximately 50% lighter than comparable aluminum components.

50% Weight reduced

Toray-developed 3D TIMON CAE analysis software also helps reduce vehicle weight by facilitating the precision design of lightweight components.
