(5) are irradiated using microwaves. (5) Material contains carbon fibres (7). DETAILED DESCRIPTION - A process for producing composite material components consisting of at least one substrate (12) and a number of thermoplastic layers (5), comprises contacting (12) and (5) at specific points, heating them to a welding temperature, and welding them by pressing them together. (5) are irradiated using microwaves. (5) Material contains carbon fibres (7). The temperature of the layers is adjusted using a control unit (8a) and an associated temperature measurement unit (8). An INDEPENDENT CLAIM is also included for apparatus for carrying out the process. USE - The process is used to produce composite material components, e.g. for aircraft and vehicle construction. ADVANTAGE - The material production is energy efficient and heat damage is avoided.de608660patent2003-10329431
