SMC(Sheet Molding Compounds) Process:

Desctiption of SMC(Sheet Molding Compounds):

      The Sheet Molding Compounds(SMC)-process is one of popular process technology for fibre reinforced polymers. It is a kind of press-flow-forming technique-to press the semifinished flat SMC -Sheet under heat and pressure in the mould. The SMC-sheet is built up continuously from short fibre (20 -50 mm) or endless-fibermats impregnated with a filled resin system.After the “SMC-Sheet” are finished it will be stored for several days so that they can reach the adequate consistency.

     The SMC-sheet will be cut roughly to the geometrical shape(round, square and so on)according to the shape of the structures (regarding the weight of the finished part - not the volume!).To put the SMC-sheet in a heated mould the uncured matrix system will drop its viscosity. The system will flow to fill the complete mould under the pressure.In parallel the curing process is starting and the cured part will be demoulded and trimmed for the final shape after a short while. This process technology can be used for mass production (automotive industry).
