The use of composite materials is not new. To look at the British Museum can be found in the ancient Egyptians had a simple but effective straw / clay mixture build their tombs. Now, for the composite material forming the mold, also known as Tool , You can use any material. For low temperature curing parts or prototype parts, the need strictly control the size of the accuracy, mold usually glass fiber, high-density foam, epoxy resin can be processed or clay or wood board. Components for high temperature curing, or in need of high dimensional accuracy, or when mold to be used for the production of a large number of components, the mold must have higher performance. Such mold materials used, including for steel (a nickel / steel alloy), steel, aluminum, nickel and carbon fiber. Die Materials Usually refer to the choice of coefficient of thermal expansion (CTE), cycle number, product tolerances, surface quality requirements, solid Chemical industry Art, the glass transition temperature, curing equipment and the cost to carry out. High-performance steel and aluminum molds are usually the first choice, but they are in the production of composite parts, also has major shortcomings. In the high temperature curing process, the molds and parts of the CTE is usually very different and incompatible. High metal alloy (for example, steel) have more similar CTE, but the processing cost is high. For large parts, the type of mold the size and weight make it hard to process, move and store. Composite mold Composite mold material if the final product with similar materials, even if the metal mold without expensive high-performance products are also available. Composite mold is just past the professional and technical personnel of aviation and F1 know an art, and now the manufacturer has been racing to aviation industry leaders (such as Boeing and Airbus) widely used. After decades of development and improvement of the composite mold is no longer such an artistic, but to become a more stable and efficient process. "The history of industrial application of composite materials has been more than 50 years," Amber Composite Materials Europe Sell Manager JedIllsley said, "Initially, the resin and fabric wet processing is used in hand lay process, but this is clearly not a precise control of resin content can be a good way. Impregnated strictly controlled in high precision instrument conditions, the fabric impregnated with resin, you can acquire a stable material, which is today known prepreg. Recently, high-precision tooling prepreg composite mold has become a standard manufacturing methods. " With prepreg performance (including operational, the service life at room temperature and the correct viscosity) gradual improvement, mold manufacturing method that has now become more convenient and economical. A new generation of composite materials are more and more areas of applications. Amber Composite Materials by a small team of experts established in 1988 in the UK, development and production of high-performance composite prepreg. Prepreg technology then in its infancy, early in the team involved in the commercial application of prepreg some research. Amber is headquartered in Nottingham County (revolutionary industrial fabric and carbon fiber industry's cradle), where they and the F1 team and many other high performance applications designed for close Cooperation . It is these high demands of customers today demand-driven development of mold materials.
