Putting fundamentals on multiphase material balance of laser based cutting polymers and natural fiber composites to practical use

Laser-based cutting and drilling of polymers and natural fiber composites has already covered a market niche, even though fundamentals of heat transfer and multiphase material balances are not well characterized up to now. Discussing the decomposition and vaporization balance, a recommendation on process parameters is given. Within this paper, criteria for laser-based production are given as well as requirements of the material. The investigation focus on strategies to control the pyrolysation and decomposition of the material as well as the prognosis of the process ability derived from laser Micropyrolysis-GC/MS correlated with industrial applications.
