The modern manufacturing process involves processing of mostly carbon fibres. Prepreg layers, cut exactly, are laid into a mould, which is packed in the so-called vacuum bag, together with other ancillary foils. This stable vacuum unit is placed into the autoclave, where there starts the program-controlled process of curing by heat and high pressure. The result is an extra firm and light product. So far, this technology has been the best processing and manufacturing of composites on the market. It is used above all in the automotive industry, aviation, motorsports and health care.
