Toyota cuts weight of ‘Lexus RC F’ with CFRP

Koji Sato, Executive Vice President, Lexus International said: 

“The new RC F and the Track Edition, in particular, benefit from constant development. With the latest improvements, these models help further distinguish the F brand by offering fast, durable, highly capable performance cars that rely on a range of technologies to help make their performance accessible to drivers of all skill levels.”

The new model has a lighter mass and an improved engine, compared with the current model, realizing a higher traveling performance. The use of a large amount of CFRP (carbon fiber-reinforced plastic) for the body most contributed to the weight reduction. Specifically, CFRP was applied to the front hood, roof, rear spoiler, etc. Also, by employing a brake made of ceramic, muffler made of titanium alloy, etc, the vehicle mass was reduced by about 70kg, compared with the current model.

For the power train, the 5.0-liter V8 normally aspirated engine was used. The engine is combined with an 8-speed automatic transmission. While the new model uses the same engine and transmission as the current model, its power performance was improved.

Tokai University places second in 2019 Bridgestone World Solar Challenge

On October 31, at their Yoyogi Campus in Tokyo, Tokai University held a post-race conference about the Bridgestone World Solar Challenge 2019, a solar car race in which the University placed second.
The Bridgestone World Solar Challenge 2019, held from October 13 to 20, is a race that runs on a solar car powered by solar cells over 3020km from Darwin, in the north of Australia, to Adelaide, in the south.

Tokai University participated as the Tokai University Challenge Center Light Power Project Solar Car Team. The race car was a 2019 model, the Tokai Challenger, with a body manufactured by Toray Carbon Magic using the M40X Toray carbon fibre product. The car’s dimensions are: 4970 x 1200 x 1000mm (length x width x height), wheelbase 1700mm, and tread 610mm. The estimated vehicle weight is 140kg.

At the briefing session, Mr Kajii, Vice President of Tokai University, said:

“Since the involved persons said it might be difficult this time, the university was under pressure, but eventually we ended up in second place. We came very close to victory.”

Mr Inoue, General Manager of Toray’s Industrial Materials Sales Division said:

“Solar cars are also a good example of the green innovation that we highly value. This is a place where the performance of carbon fibre materials can be fully demonstrated.” Regarding the Torayca M40X material used in the car, he added: “It increases the strength and elastic modulus to the maximum, improving strength by 30% while maintaining an elastic modulus equivalent to conventional carbon fibre. The M40X greatly contributed to its reduced weight.”

Ube Industries completes concept car using plant-derived materials
On October 23, Ube Industries completed a concept car using plant-derived cellulose nanofibre (CNF) parts. The company has participated in the NCV (Nano Cellulose Vehicle) project launched by the Ministry of the Environment and has been studying the assembly of composite materials suitable for automotive parts made of CNF and nylon. Ube Industries has also been prototyping and providing materials.

Ube Industries completes concept car using plant-derived materials

The NCV project was launched in 2016 with the participation of more than 20 research institutions and companies such as Kyoto University and the Japan Association for Industrial Environment Management.
The goal is to limit CO2 emissions by reducing the weight of cars through the use of materials (composite resins, etc.) based on CNF, a plant-derived material that is 1/5 lighter than steel and five times stronger. 

The application of CNF to automobile parts is one of Japan’s top technologies. Ube Industries took advantage of this technology and knowledge as the leading domestic manufacturer of nylon and completed the concept car.

Sustain heat vest: a tech vest equipped with carbon fibre heaters
The Sustain heat vest is equipped with a patented heater technology combined with a high-performance thermal insulation material to keep the warmth while being thin and stylish. The vest is powered by a patented Japanese carbon fibre technology with a low energy conversion rate.

The Sustain heat vest has two carbon fibre heaters in the chest and one in the back and neck that make it possible to warm the body at a suitable temperature of 42°C or 46°C.

These high-performance heaters are designed to save energy and generate heat for a long time with a single mobile battery. For example, by using a 4,000mAh mobile battery, the temperature will last up to 2.5 hours at medium temperature (42°C) and up to 1 hour 50 minutes at high temperature (46°C).

Carbon fibre heaters are flexible and can be washed, making them the best for everyday use.

Because it uses special fibres combined with antibacterial silver nanoparticles, the heat vest can be worn comfortably even in outdoor environments.
