Automated layup processes are highly suitable for an efficient production of carbon fiber reinforced parts, especially for aerospace applications. Heat input by means of radiative heating offers advantages for these processes and is well established in different forms. The presented work reviews sthe modelling of radiative heatin in automated layup, covering thermoset and thermoplastic materials. Laser and infrared heat sources are studied with their characteristics, similarities and differences, as well as optical interaction with the material. Numerical modelling of the heat transfer is presented with an emphasis on implementation of radiative heating.
