Japanese company on Wednesday said it has developed a process to make lightweight car frames at mass production speeds, a process that could make vehicles more efficient and save energy.

Teijin Limited said in a press release it can mold an automobile frame of carbon fiber reinforced plastic in under 60 seconds.

"The breakthrough overcomes one of the biggest challenges in the industry and represents a long stride toward the use of carbon fiber for the mass production of automobiles and other products," the company's statement said.

The company said it has developed an electric vehicle to show the advantages of its new carbon fiber composite. The frame of the vehicle weighs only 47 kilograms (103 pounds), a fifth of what a metal counterpart would weigh, it said.

Previous molding processes for a car frame took at least five minutes each, the company said, making it unsuitable for mass production. With the new method taking less than a minute, efficient mass production is possible, it said.

Teijin plans to develop applications for the carbon fiber in making machine tools and industrial robots as well as automobiles, the statement said.

Is this really feasible? I was under the impression that mass production of carbon fiber structures like this was still too slow and the fiber too expensive to make?

Obviously I'm wrong, but what happned to make this possible?

Processes are developing since the good old days of hand made parts?

Heh, yeah... but with carbon fiber? I feel like a blinked and missed something...

All that happened was that somebody realized how big the market is. This is no different in principle from the development of cheap digital cameras, computer printers, etc.

Of course if you live in a country where 40% of the population thinks religion trumps science, and a large number think global warming is a myth, that may explain why the innovations are happening some place else.

The 3-years-late-and-counting Boeing 787 is hardly a shining example of successful technological innovation, but check out where the composite material components are coming from. The answer isn't Seattle.

Ooof... well, I guess that counts as the obvious answer, and the best one... bit painful, but also undeniable.

Thanks AlephZero!
 

1. What is a carbon fiber car frame?

A carbon fiber car frame is a type of car frame made of a strong and lightweight material called carbon fiber. It is made by weaving together thousands of carbon fibers and bonding them together with a resin. This creates a very strong and rigid structure that is also lightweight, making it ideal for use in high-performance vehicles.

2. How does a carbon fiber car frame compare to a traditional steel frame?

Carbon fiber car frames have several advantages over traditional steel frames. They are significantly lighter, which can improve a car's fuel efficiency and handling. They are also stronger, which can improve the overall safety of the vehicle. Additionally, carbon fiber frames are more resistant to corrosion, making them a more durable option.

3. Are carbon fiber car frames more expensive?

Yes, carbon fiber car frames are generally more expensive than traditional steel frames. This is because the production process for carbon fiber is more complex and the material itself is more expensive. However, the cost of carbon fiber is decreasing as technology advances, making it more accessible for use in cars.

4. Are there any downsides to using a carbon fiber car frame?

One potential downside of using a carbon fiber car frame is the cost, as mentioned before. Additionally, repairing a carbon fiber frame can be more difficult and expensive compared to a traditional steel frame. Carbon fiber can also be more brittle than steel, making it more susceptible to damage from impacts.

5. Are all cars using carbon fiber frames?

No, not all cars use carbon fiber frames. While it is becoming more common in high-performance and luxury vehicles, it is still not widely used in mass-produced cars. The cost and production process may be a barrier for some manufacturers, but as technology advances and costs decrease, we may see more cars using carbon fiber frames in the future.
