a piece of silk be? High strength, high model, large tow, three categories of "stunts", what is the difference between them? The name of
this "silk" is not unfamiliar to us,
it is carbon fiber ,
known as "black gold" reputation. Carbon fiber
with a cross-sectional area of
1 cm ² can pull a large C919 aircraft ; As
small as badminton rackets, fishing rods, bicycles,
as large as wind power blades, large aircraft, carrier rockets,
high-end manufacturing of "steel and iron bones",
there are many "silk fabrics"! Ccement. Com/file/news/20260703/6a478a147167d6451294.
Xiaoxin observed the "past and present life" of
tens of millions of "silk" on the production line.
Three categories, each with "stunts",
high-strength, high-modulus, large tow,
what is the difference between them?
High modulus:
the maximum stability
modulus of the world's largest production line
with an annual output of 600 tons of M40 or above is higher, the stress and thermal deformation is smaller, and
the dimensional stability is stronger.
Generally speaking, it is "not out of shape". Carbon fibers
above M40 can serve in
deep sea, deep space, deep earth, competitive sports equipment,
precision instruments, 3C electronics and other fields, and
can hold the last line of defense for equipment accuracy in extreme environments
. It will not fail due to minimal deformation during
long-term operation,
prolong the service life of equipment and reduce fatigue loss.
Large tow:
The world's largest SYT45S-48K production line
with an annual output of 5000 tons is extremely "down to earth"
. K stands for "thousand".
A large tow of 48K contains 48000 monofilaments.
This seemingly soft bundle of "silk"
is a key step for carbon fiber to move from "luxury goods"
to "daily necessities":
when used in wind power blades,
it can reduce the use of carbon plates by 8% -12%. When
used in new energy vehicles and hydrogen storage equipment,
it can greatly reduce the weight of the structure and
effectively improve the endurance and energy efficiency.

Among them, SYT45S carbon fiber is applied to 131 meters onshore wind turbine blades and 153 meters offshore anti-typhoon blades, which can reduce the material consumption by 10% under the same load. The hub center height of the test unit is 185 meters, which is equivalent to the height of a 63-storey residential building, and the swept area of the wind wheel is equivalent to 10.5 standard football fields . A single unit can output 100 million degrees of clean electricity every year, which can meet the needs of 5. Bicycles to the subway, "weaving" the production line to improve the quality of life to visit the site. Many visitors gathered around a bicycle and observed that they were carrying out a challenge: lifting the bicycle with two fingers. The subway can also be "silk weaving" . June 26, 2024, CETROVO, the world's first carbon fiber metro train for commercial operation 1. Zhongfu Shenying SYT49 (T700 class) carbon fiber has become the main material of the vehicle's load-bearing structure-bogie beam. Compared with the traditional metal material metro vehicle, the carbon fiber composite component bogie crossbeam formed by two processes reduces the overall weight by 50%. It integrates the advantages of light weight, high strength, fatigue resistance and corrosion resistance, and has the advantages of lighter and more energy-saving, which is an excellent material for lightweight rail vehicles. The https://img7.ccement.com/file/news/20260703/6a478a2a0c5f95088307. used to, China's carbon fiber industry has long faced the structural contradiction of insufficient supply of high-end products and incomplete product pedigree. T1100 grade and high modulus products are highly dependent on imports, and large-scale production capacity of large tows is lacking. High-end carbon fiber can make samples, but it is not stable for mass production. Today, three world-class production lines have fallen at the same time, and the three goals of "making, stabilizing and supplying" have been achieved at one time. Domestic carbon fiber not only realizes the self-control of the whole chain from technical equipment to products, but also has the comprehensive strength to participate in the global high-end material market competition. This is a powerful verification of the path of "long-term investment, chain tackling and leading traction" , and also provides a replicable practical model for other key strategic materials fields in China. Square inch filament supports the manufacturing of big countries. This bundle of "Chinese silk" is closely "weaving" the future.
