Das Verhalten faserverstärkter Kunststoffe beim Laserschneiden

The pattern of organic emissions, which are produced by processing of fiber reinforced plastics with laser beam was studied and the concentrations of the main components determined. Despite the application of plastic materials with different chemical structures, the observed patterns are very similar. Mainly aromatic hydrocarbons are emitted, especially benzene and toluene, as well as some heteroatom-containing aromatic hydrocarbons. By use of oxygen as process gas the emissions during cutting of glass fibre reinforced plastics can be reduced, while they will be constantly high with aramide fibre reinforced plastics.
