Carbon fiber material has the advantage of being lightweight and stronger than both conventional steel and aluminum. The expense is undoubtedly a disadvantage. Because it requires more effort and technology, the material is more costly. It has become more inexpensive, although it is still mostly utilized in premium sports vehicles. The advantages of carbon fiber material are its strength and light weight. The disadvantages are its cost and lack of diversity. There are many types of carbon fibers, but they can be divided into three main groups: prepregs, woven fabrics and filament-wound components. Prepregs are sheets or mats of carbon fiber that are coated on one side with a resin. They require special equipment to manufacture and are therefore expensive. However they offer great design flexibility because you can cut them to shape and glue them together. We have seen some prepreg furniture made from this material. Woven fabrics are produced by weaving yarns (or threads) into a fabric. The carbon fibers are then pulled through these threads at right angles, resulting in a mesh structure. These fabrics are low-cost to produce and can be used in large quantities for applications where their price isn't important. However, they cannot be cut or shaped after production and so can only be used in one location. Filament-wound components consist of a central core surrounded by a layer of fiber that is wound around the core using a machine.
