Reconstitution of composite with surface- or deeper defect, including foam structures normally heated with difficulty

摘要

To heat the replaced section (2) a single radiant (6) emits infra red, the bandwidth ranging over wavelengths 1-10 mu m. It is located to heat the defect area, by irradiating the evacuation hood over the piece replaced, and other added layers, which are compressed. Preferred features: The radiant (6) is a catalytic burner (7). The evacuation hood is transparent to its infra red radiation. It is placed directly opposite the textile gas-venting layer (3). The sealing film (8) facing the plastic material is inserted between the hood and the venting fabric. A non-adherent film (9) facing the replacement section, is inserted between it and venting fabric. A variant based on the foregoing principles, forming a composite object, is also described.
