Material processing temperature can have a significant effect on Automated Fibre Placement (AFP) quality. Temperature is commonly measured using infrared cameras, which require an effective emissivity value for accurate measurement. A bespoke experimental setup was created to replicate AFP heating conditions and investigate the effect of external factors on effective emissivity for three separate processing materials. Effective emissivity was found to have a high variation at low temperatures and increase greatly with the presence of an AFP roller. For polyether ether ketone impregnated tapes, effective emissivity was shown to change behaviour at approximately 155°C, steadily increasing. These relationships can be used to improve temperature measurement and control for the AFP process.
