ABSTRACT:
The automated tape placement of the thermoplastic carbon-fibre composite AS4/PEEK using a near-infrared (NIR) diode laser heat source has been recently developed and shows great advantages as a manufacturing process. So far, there has not been any work done on the effects this process could have on the molecular level. It is therefore necessary to investigate what is occurring at the surface of the material after it has been heated by the laser and the resulting level of thermal degradation at the surface of the tape. This investigation has been performed using the technique of attenuated total reflectance Fourier Transform Infrared spectroscopy (ATR FT-IR).
