There's a new cutting-edge material

Only a tenth of the thickness of a human hair and a chopstick can pull two C919 aircraft This is known as "black gold" carbon fiber

From making a piece of fiberglass steel to carbon fiber production capacity, the world's first central enterprises in the field of composite materials continue to achieve key technological breakthroughs with "national materials" to help China's "smart" manufacturing all the way forward

Although carbon fiber is called "black gold," in fact, some high-performance carbon fiber is more scarce than gold to see how good it is

Carbon fiber is used to make trains that help increase speed

Carbon fiber

For aerospace

It could help make manned spacecraft lighter and stronger, with greater carrying capacity

Carbon fiber used in wind turbine blades can enhance blade rigidity and improve power generation efficiency

Carbon fiber used in construction projects can improve the seismic performance and bearing capacity of buildings

You know carbon fiber so good production is quite complex for a long time carbon fiber technology has been dominated by the United States and Japan, even the former Soviet Union has not been able to overcome this difficulty and more than 60 years ago, let alone carbon fiber in the field of composite materials even a piece of fiberglass steel can not be made

Fiberglass: Not glass, not steel

What is the relationship between FRP and carbon fiber? Let's take a look at the production process of FRP: melt the glass and pull it into a very fine fiber wire and then combine it with the resin to form FRP. The purpose of doing this is only to get a stronger composite material. Glass fiber and carbon fiber play the role of fiber reinforcement in the composite materialYou know carbon fiber so good production is quite complex for a long time carbon fiber technology has been dominated by the United States and Japan, even the former Soviet Union has not been able to overcome this difficulty and more than 60 years ago, let alone carbon fiber in the field of composite materials even a piece of fiberglass steel can not be made

So fiberglass is neither glass nor steel it's essentially a plastic so why is it called fiberglass?


When the time came to the 1950s, Comrade Lai Jifa, then vice minister of heavy industry, led a delegation to visit the Soviet Union and saw that the tank shell was still intact after the high temperature ablation after the atomic bomb explosion. The special material for making the tank shell is fiberglass steel. When he returned home, he specially brought back a sample of material he wanted to make this material in China!


In 1958, the development of FRP started from the glass ceramic Research Institute of the former Ministry of Construction Engineering (the predecessor of China Building Materials sub-enterprise China Building Materials General Institute), 7 comrades were selected to form a scientific research team and began to explore the samples brought back from the Soviet Union

The good news is that alkali-free glass fibers were first successfully developed how to press these glass fibers into plates? At that time, did not master the hot pressing process technology in the repeated trial and error of drying materials with the oven exploded two finally 4 months later, the scientific research team successfully pressed out China's first glass steel plate it is 1.2 meters long, 0.5 meters wide, 5 mm thick to now is not what can be achieved at that time but achieved a "zero" breakthrough
