Whether you are a car enthusiast or enthusiast, as long as you want to buy a car or have more contact with a car, you may have heard the saying: Japanese cars are "light". Indeed, the first to introduce lightweight is Japanese cars, and now many models, including German and American models, are also on the journey of "losing weight". Recently, Japan Textile Co., Ltd. jointly developed a new polyurethane composite material for the new electric concept car LQ of Toyota Motor Company, which also means that Toyota has made a big step forward in the road of lightweight automobile. At present, lightweight materials will play an increasingly important role in future travel. The research shows that if the vehicle mass is reduced by 10%, the fuel efficiency can be increased by 6% - 8%; if the vehicle curb weight is reduced by 100kg, the fuel consumption per 100km can be reduced by 0.3-0.6l; the vehicle "weight reduction" will further extend the range of electric vehicles. Toyota Motor Co., Ltd., known as the "cost killer", has always been the leader in vehicle lightweight, and Toyota Textile Co., Ltd. is the auto parts manufacturer of Toyota. This new material combines the advanced bayprg? F NF technology of covestro and the expertise of Toyota textile in the field of hemp fiber, providing a lightweight and sustainable solution. The new product is used in the door panel of Toyota LQ, which is 30% lighter than the door panel made of traditional materials. This is the first time that Toyota has used this material in its models around the world. At present, the vehicle lightweight is committed to achieve the weight minimization under the cost optimization, cost and weight coordination under the performance optimization. The hemp fiber comes from the bast fiber of the hemp plant. The raw material has high cost-effectiveness and good mechanical properties, and is attracting more and more attention. In the automotive industry, plant fiber as an alternative raw material is also attracting more and more interest.
