I enclose a brief look to give you an idea of how a carbon fiber product is formed.

Finished created tools for the production of a component.
Carbonworld is one of very few companies, that undertakes a “pressing” technique.
The customers can see this clearly with evidence of the smooth insides
The benefits -in contrast to vacuum-, injection- and autoclave technique are the defined wall thickness and the warping of the later component, furthermore also gives a very good fit.
Cuttings of carbon weave are stored as a form of tissue on a roll.
Quick advice! Misleading information circulating in Internet portals:
Basically, cost efficiency most certainly exists with the use of carbon fiber.
-Replacing a few layers of carbon fiber with glass fiber (fiber glass usually costs 1 / 10 of carbon fiber material).
Thus, the product must be overlaid with a carbon fiber layer (rest glass fiber), which is not necessarily bad. Only the cost and weight are very different.
-We only use epoxy resin, which possesses properties that are needed for perfect parts. Polyester resin or vinyl ester resin is often used in the glass fiber area. However this does not meet our requirements and costs only 1 / 3 of the price.
Our philosophy, however, takes a backstep from these practices, as in our opinion these are not meant to fit a Ducati or MV Agusta.
Insertion of carbon layers into the mould.
No matter how many ideas we develop or transpose in this area , one thing remains:
The man: a component, that is still 80% handmade.
A misdirectional fiber look is unavoidable, though the fiber is perfectly woven;
Making a simple plate is easy, but just try the fiber in a three - dimensional form without inserting fabric cuts!
Thereafter, the various layers are impregnated with epoxy resin,
followed by being pressed under heat.

Protruding fibers and clippings must be milled. Image shows the processing of a 016ed7 clutch cover.
Our components are equipped with a special UV-resistant outer layer. This helps to avoid yellowing of the components. We offer 2 years warranty on all of our parts.
Sometimes, a subsequent clear coating is used, it is just as effective to protect the components. However, this method increases the weight and provides a risk of dripping affecting the fit.
Below is some additional information about the autoclave / prepreg processes.
In the composite field they are needed for many different applications, different manufacturing processes, and have run in the years already mentioned.
When one wants to manufactur aircraft wings particular requirements, or monocoque F1 chassis, or large automotive components-the method used would surely be the best thing you can do.
However, for producing a small part such as a heel guard, this is simply the wrong procedure, so you end up with a higher output price but that's all.
The weight is not reduced and the stiffness is also not much better.
I am referring to this statement, only in comparison to our production processes, not to other procedures.
A prepreg is a carbon fiber impregnated with resin, which hardens under heat and pressure.
The autoclave is a pressure chamber and an oven at the same time. The device is placed under vacuum in the autoclave and cured there.
If you wish to purchase such a part, be sure to pay attention to the subsequent coating,
Otherwise your product will not bring much satisfaction.
Only a "polished finish" is not enough and is guaranteed not to be UV resistant.
