Carbon fiber (CFRP)
Carbon fiber not only has inherent intrinsic properties of the carbon material, and both soft workability textile fibers. It accounted for less than a quarter of the steel, but the strength is very strong. And its outstanding corrosion resistance, is a new generation of reinforcing fibers. Carbon fibers are widely used in civilian, military, construction, aerospace and super sports cars.
Frame advantage
Carbon fiber frame is characterized by a "light, steel is good, good shock absorption," however, give full play to the excellent performance of carbon fiber, technically does not look so easy, quality carbon fiber material differences between the manufacturers as well. Bicycle manufacturers consider the cost issue, unlikely to be used to produce high-grade carbon fiber frame. Despite these practical problems, but has the advantage of carbon fiber frame, or other materials that are not possible to produce a lightweight bicycle 8,9kg about this lightweight carbon fiber bike, climbing the hill when most can manifest its advantages, successfully climbing the hill and refreshing. And not as some light aluminum frame, while climbing the hill felt a pull back force.
(1) can be made lightweight frame
Carbon fiber frame is facing the direction of the carbon fiber is laminated to stress and to give strength. Carbon fiber frame is very light, which is its density and stronger tensile strength composition.(2) Good shock absorption
With carbon fiber used to make prosthetic leg movement disabilities or special spring is used in various fields. Using its excellent performance in absorbing impact, without making shock absorbers bike. As SCOTT plant ELEVATED frame is known. But the quality difference between the various manufacturers of large, some very hard, so after this ride frame in order to know good or bad.
(3) can be produced in various shapes frame
The basic method of forming the carbon fiber is spread in a mold and then flows into the resin fiber sheets and baked. Frame can be made into various shapes, such as the Y-frame TREK.
Frame disadvantage
(1) The complexity of the stress calculation
Carbon fiber frame is composed of carbon fiber, which is characterized by strong tensile strength, shear strength but weak when processing requires complicated stress
calculations (longitudinal rigidity, transverse rigidity), according to the calculation of the carbon fiber sheet molding overlap. Processing technology manufacturers vary, you should choose an experienced and reliable manufacturers of products is very important.
(2) it is difficult to change the size
Since ready after molding, it is difficult to change the size. Unable corresponding multi-size models of more orders.
(3) Aging
Resin and therefore does not age? This is a problem exists, it will gradually turn white when it is placed in the sun. Of course, this phenomenon is related to the manufacturer's technical. Should not be placed in the sun.
species
Full carbon
All carbon fiber bike accessories, all made of carbon fiber material.
Semi-carbon
Many bike aluminum alloy + carbon fiber manufactured. For example, a frame, the tube may be made of carbon and other parts of the aluminum alloy (triangle using carbon or after ...), carbon fiber fork arm, fork tubes aluminum alloy, so it can be said that half of the carbon .
Carbon package
Some frame, handlebar, stem, crank, fork, seatpost and other accessories, manufacturers use aluminum production, and in the surface layer of carbon cloth bag, which is what carbon package.
