The pattern of the organic emissions, which are produced by processing of fibre reinforced plastics (epoxy resins reinforced by aramid and glass fibres and phenol resins reinforced by aramid fibre) 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 (e.g. phenol). 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 aramid fibre reinforced plastics.
研究了用激光束加工纤维增强塑料（芳纶纤维和玻璃纤维增强的环氧树脂以及芳纶纤维增强的酚醛树脂）时产生的有机排放物模式，并测定了主要成分的浓度。尽管使用了具有不同化学结构的塑料材料，但观察到的模式非常相似。主要排放的是芳烃，尤其是苯和甲苯，以及一些含杂原子的芳烃（如苯酚）。使用氧气作为工艺气体时，玻璃纤维增强塑料切割过程中的排放可以减少，而芳纶纤维增强塑料的排放则会持续很高。
