Carbon fiber not only has the inherent characteristics of carbon materials but also has the soft processability of textile fibers. Its specific gravity is less than 1/4 of steel, but its strength is very strong. And its corrosion resistance is outstanding, it is a new generation of reinforcing fiber. Carbon fiber is widely used in civil, military, construction, aerospace, and super sports car fields.

Carbon Frame advantages

The carbon fiber frame is characterized by "lightweight, good rigidity, and good impact absorption". The carbon fiber frame has advantages that other materials do not have. It can manufacture lightweight bicycles of about 8 or 9kg. This carbon fiber lightweight bicycle best reflects its advantages when climbing a hill, smooth and refreshing when climbing. Unlike some light aluminum alloy frames, it feels like a kind of pullback when climbing a hill.

(1) A lightweight frame can be made

The carbon fiber frame is made by layering carbon fibers against the direction in which stress occurs to obtain strength. The carbon fiber frame is very light, which is due to its density and strong tensile strength.

(2) Good shock absorption

Carbon fiber is used to make artificial legs for the disabled when exercising, or special springs are used in various fields. Make use of its excellent shock absorption performance to make bicycles without shock absorbers.

(3) Frames of various shapes can be manufactured

The basic forming method of carbon fiber is to spread a fiber sheet on a mold and then pour into the resin and burn it. Can be made into various shapes of the frame.

Carbon  Frame disadvantages

(1) Complicated stress calculation

The carbon fiber frame is composed of carbon fiber, which is characterized by strong tensile strength but weak shear strength. Complex stress calculations (longitudinal rigidity and lateral rigidity) are required during processing, and the carbon fiber sheets are overlapped and formed according to the calculation. The processing technology varies from manufacturer to manufacturer, and it is important to choose products from experienced and reliable manufacturers.

(2) Difficult to change the size

It is difficult to change the size due to the molding after the mold is made. Cannot respond to orders of multiple sizes and styles.

(3) Aging

Will the resin age because of this? This is an existing issue, it will gradually whiten when placed in the sun. Of course, this phenomenon is related to the manufacturer's technology. It is best not to place it in the sun.

Species of carbon

Full carbon

All carbon fiber bicycle accessories are made of carbon fiber materials.

Half carbon

Many bicycles are made of aluminum alloy and carbon fiber. For example, a frame may be made of carbon for the upper tube and aluminum alloy for other parts (or carbon for the rear triangle...), the front fork arm is made of carbon fiber, and the front fork tube is made of aluminum alloy. This can be said to be semi-carbon. .

Carbon-coated

Some accessories such as frames, handlebars, stems, cranks, front forks, sitting rods, etc., are made by manufacturers of aluminum alloy, and then a layer of carbon cloth is covered on the surface, which is what is covered with carbon.

Note:
Carbon fiber contains resin, so it can be said to be acid-resistant. However, for carbon fiber, internal factors should be considered. It uses resin, so the possibility of resin aging exists. Carbon fiber bicycles should be kept away from sunlight when not in use, as sunlight and ambient temperature have the greatest impact on it.
