According to foreign media reports, the BMW engineers Florian Schek in the management of the center for automotive research in the United States's briefing seminar, said because the price is very high carbon fibre material, the cost is difficult to reduce, the application will not be in the car so optimistic.

Carbon fibre materials cause concern in the automotive industry

In 2012, someone at a management briefing conference predicted that carbon fiber would become a vehicle material and would be increasingly favored by car companies and users.

At the time, one of Dow's engineers said: "carmakers are bound to look for alternative production materials, and fibre complexes are bound to be selected."

So what is the attraction of the carbon fiber complex? The material is hard, anti-fatigue, corrosion-resistant and lightweight, and the car companies most value the last feature. In an effort to boost fuel economy for its vehicles, many carmakers are struggling to lose weight on their vehicles.

"Carbon fiber reinforced composites will be the next generation of automotive materials," a senior audi executive predicted at a conference in 2012.

High cost of carbon fiber is limited

At this year's meeting, however, a BMW engineer said: "the situation is not very optimistic" when it comes to the use of carbon-fibre reinforced composites in cars.

There is only one reason: the price of carbon fibre is always high. There have been many talks in the industry in the hope of setting up a purchasing consortium (purchasing consortiums) to reduce its costs, but not much has been done.

Florian Schek, engineer in charge of BMW's lightweight design and vehicle weight, said: "the main challenge to the application of carbon fiber materials is its high cost and the difficulty of the technology."

At present, the use of carbon fiber reinforced composite materials is very limited. It is only used in the body and chassis of formula one racing cars and expensive ultra-luxury models.

According to Schek, BMW's latest generation of BMW 5-series models, which are not made of carbon fiber, are lightweight materials for aluminum and magnesium alloys.

But BMW 7-series sedan body USES a lot of carbon fiber reinforced composite material, and the BMW i3 electric car, the BMW i8 plug-in hybrid vehicle's passenger compartment (occupant cells) also USES the carbon fiber material
