Based on its innovation leadership, Covestro was chosen as partner by Toyota Boshoku Corporation, a car component manufacturer of the Japanese Toyota Group, for jointly developing a new polyurethane composite material for new electric concept car “LQ” developed by Toyota Motor Corporation.

 

The material is based on a combination of Covestro's advanced Baypreg F NF technology and Toyota Boshoku's expertise in using kenaf fibers, and offers a lightweight and sustainable solution.

In the “LQ”, the new product is used in door trims, where it makes its world premiere in a car model of this manufacturer. 

 

Kenaf is a member of the hibiscus family and is growing in regions such as South East Asia, Bangladesh, India and Africa. The fiber is obtained from bast fibers of the kenaf plant and has recently attracted increasing attention as a cost-effective raw material with good mechanical properties.

 

The kenaf fiber-reinforced polyurethane foam composite is characterized by a very low area density of less than 1 kg/m2 and high strength, making the door trim made of the fiber-reinforced kenaf polyurethane foam 30% lighter than that produced from conventional materials.

 

The new composite material was developed in close cooperation between Toyota Boshoku and Covestro's recently renovated Japanese Innovation Center.

The polyurethane composite is based on a combination of Covestro's advanced Baypreg F NF technology and Toyota Boshoku's expertise in the use of kenaf fibers. In the “LQ”, the new product is used in door trim panels.

 

“Our joint development makes an important contribution to the design of particularly lightweight and sustainable vehicles,” says Hiroaki Ido, Head of Polyurethanes Application Development for Transportation at Covestro's Japanese Innovation Center.

 

In the automotive industry, the plant fiber is also attracting increasing interest as an alternative raw material.
