The composite material
The composite material is said that the composite consists of two distinct parts: fiber and resin.
The fiber may be carbon, Kevlar, glass. The type of resin and epoxy, but now there are also studied resin type metal. Carbon fiber is very strong, but, like all the fiber, to build a piece that has a form and substance of the resin needs. It is the work of the resin that makes the product very strong composite, the fiber is strong, but the resin is to work together all the fibers. As soldiers, advancing graded. The great advantage of the things the composite material is that we can arrange the fibers in the direction in which we think is necessary. So we can build a handlebar that no bends, or a comfortable frame and capable of absorbing vibrations. The metal offers the same strength in all directions, the fiber is very strong for this long, but it is easy to defend, just like an arm pit. So when we realize the piece have the fibers according to the plan, the bicycle is usually all for the long, and we use tissue-type way, that have made all the fibers for long. Then in the areas of reinforcement, and conjunctions, we use cross-woven with fibers at 45 °, to have a good resistance to twisting, as in the lower part of the racing handlebars. Finally there is the layer of finish, aesthetic, which is what we see. It may be a cross-1k, 3k or 12 k. The number indicates the width of the bundle of fibers. Then k 1 will be a fine fine squares, k 3 is usually used for components, 12 k is the picture big enough to be in fashion today. To see how the fibers are arranged in one piece, just burn it. In fact, the burning resin and fiber remain, so you can see how willing the various layers.
Materials in pipes Puma series:
The tubes are made of Pre-preg (prepregs) of carbon. These "coating" of carbon fiber which is deposited on the epoxy resin in a controlled manner for a product (the prepreg note) very stable with the percentage of resin than the carbon fiber well distributed and constant. In this way the artefact resulting presents high repeatability presenting the same percentage of resin and carbon fibers. The rolling tube involves the use of UD carbon in the intermediate layer (with axial fiber is either ± 45 °) and a skin of fabric 3K Plain finish. All of the carbon fibers have high strength of the Family Toray T600.
