How to make a carbon fiber bike frame

 What we call carbon fiber is really a material with carbon because the main material. Carbon fiber material isn't the sole material in bicycle frames, rims, and carbon strips. this is often because the ultra-high rigidity of carbon fiber features a technological premise. When the fabric is 100% carbon fiber material , it's very fragile and features a tendency to tear within the direction of the fiber. so as to exert its rigidity, the carbon fiber cloth are going to be dipped in epoxy before being processed into the mold to make a material . The carbon fiber a part of the bicycle is processed through such steps. The resin will form the key role of keeping the carbon fibers together and increasing the toughness and sturdiness of the carbon fiber cloth. The carbon fiber after soaking within the resin and plasticizing could also be deformed but not broken when encountering impact and vibration, so on achieve the bicycle material. the right performance is required.

Carbon fiber may be a very amazing material. Its rigidity is totally different from that of metal. The rigidity of carbon fiber products is simpler to regulate , and therefore the rigidity characteristics are often realized in one direction. Before making the frame model, the type, strength, fiber direction, and fit of the carbon cloth The direction may be a means to regulate the general performance of the frame, so its rigidity could also be adjusted consistent with how the carbon fiber material is adjusted into a line or how it's placed within the mold. this is often called anisotropy. On the contrary, metal is isotropic and exhibits an equivalent strength and stiffness properties in any axial direction of the fabric . additionally to winning the performance of varied metals, it's the advantage of being lighter than other materials we are conversant in .

With the advancement of carbon fiber processing technology, frame engineers use carbon fiber anisotropy to coordinate and mix the strength level of carbon cloth, the quantity of leaching material, the form and size and direction of carbon fiber strands, and therefore the Position to regulate the carbon price or the performance of the carbon wheel. The carbon fiber mountain bike frame is thru this method, on the brink of the last word balance of infinite lightweight and geometric strength, so there's never-ending process space for carbon fiber.

The carbon fiber parts are processed in one-piece baking and casting molding, also as splicing and bonding molding. the 2 molding methods have their own advantages and drawbacks , but generally , the integrated carbon fiber frame is more beneficial and difficult to product performance.

Manufacturing steps

1. Weaving carbon yarn, which is that the embryonic fabric of carbon cloth
The first is to weave and make carbon yarn into carbon fiber composite materials of varied specifications. the method of weaving yarn is analogous thereto of weaving. it's to form the carbon yarn into the carbon cloth staple employed by mechanical spinning consistent with technical standards, then soak the carbon cloth. The corresponding resin solution is then dried and formed to repair the carbon cloth, and sometimes it's stored in cold storage for the deformation of the textile carbon yarn.

2. Cut carbon cloth to collage various parts

Scientifically cut the carbon yarn and mark each bit of carbon cloth intimately . Each Chinese carbon mountain bike is formed of many different carbon cloths. The Dazhang carbon cloth will first be roughly dig easy-to-operate sheets. A frame is perhaps made from quite 500 pieces of independent carbon cloth. Each model requires a selected sort of carbon cloth. albeit an equivalent mold is employed , the quantity of carbon fiber is different.

3. Stick the carbon yarn soaked with resin on the core material

Again, it’s the roll chat, that is, the cut carbon fiber prepreg is laid on the core material during a specific order and angle to form it have the form of the frame, expecting subsequent step to solidify. The roll material operation is during a closed dust-free workshop The environmental requirements are very strict.

4. After the coil is put into the mold, it's formed by high-temperature die-casting

In the forming stage, the rolled product is placed within the forming mold and extruded at heat . The carbon fiber mold is additionally a technology and cost-intensive link. it's necessary to make sure that the mold and therefore the frame have an equivalent thermal expansion rate, which is vital for ensuring the accuracy of the frame. It plays a really important role, especially in today's day when the manufacturing precision requirements for bicycles are becoming higher and better .

5. The parts are cured into an entire shape after bonding and baking

For the parts that can't be integrally formed, they need to be formed by special glue between the parts, then baked at heat to make an entire whole. At this point , the glued frame are going to be clamped on a special carbon fiber fixture and sent The curing process is administered within the curing oven. When the curing process is completed, the frame are often taken out of the curing oven and faraway from the fixture.

6. Grinding and drilling of the frame

Finally, the frame is hand polished, trimmed, and drilled. After polishing, the trimmed frame are often finished with spraying and decals. The wet transfer decals should be applied before varnishing. Then a part of the gorgeous and high-energy carbon price is completed.

7. Spraying at the top of the labeling procedure
