Abstract
Procédé de fabrication de pièces composites comprenant une armature métallique constituée d'une structure en treillis, enrobée de polytétrafluoréthylène. Il est caractérisé par le fait que l'on dispose sur chaque face d'une structure en treillis métallique, une bande poreuse de polytétrafluoréthylène présentant une densité comprise entre environ 0,6 et environ 1,5, que l'on soumet l'assemblage ainsi réalisé à un chauffage sous pression de manière à réaliser le frittage du polytétrafluoréthylène, et que l'on effectue un refroidissement sous pression de la piece composite obtenue.
