METHOD AND DEVICE FOR DRAPING AND BONDING A TEXTILE STRIP INCLUDING HEATING BY MICROWAVES

摘要

The invention relates to a device (190) for heating and applying to a preform (100) a textile strip (111, 112) comprising a fibrous reinforcement and a polymer, characterised in that it includes: a. a metal antenna (120) connected to a magnetron by a waveguide (121) and including a radiating surface directed towards the preform (100) capable of producing electromagnetic radiation at a frequency ∫; b. an inserted shim (130), made up of a dielectric material with low loss factor at the frequency ∫ between the radiating surface of the antenna and the preform (100); and c. means for securing the inserted shim to the antenna (120).
