Method for applying an anti-oxidative coating on brake disks of a carbon-containing composite material
Jacques Thebault,Laxague Michel,Jacques Rey,Rodolphe Delaval,Gérard Palavit +4 more
- 05 Apr 1995
TL;DR: In this paper, the impregnation is obtained by creating a pressure differential between the exposed surfaces of the immersed brake disk and the inside of the inner open pores of the disk, without creating a to-tal internal vacuum.

Thermostructural composite structure with a compositional gradient, its manufacturing process
Jacques Thebault,Laurent Jean Pierre David +1 more
- 11 Apr 2006
TL;DR: In this paper, the authors proposed a composite structure with compositional gradient, formed from a porous core made of a refractory having a pore volume content of greater than or equal to 80% and two monolithic ceramic shells (7 a, 7 b) covering the intermediate layers in order to give stiffness to the entire structure.

Method of manufacturing a part out of impervious thermostructural composite material
Jacques Thebault,Bouquet Clement,Laxague Michel,Evrard Herve +3 more
- 14 Apr 2005
TL;DR: In this article, a method of manufacturing a part out of impervious thermostructural composite material is proposed, which consists of forming a porous substrate from at least one fiber reinforcement made of refractory fibers, and densifying the reinforcement by a first phase of carbon and by a second phase of silicon carbide.

Chemical vapour infiltration method with variable infiltration parameters
Jean-Luc Leluan,Domblides Jean-Luc,Bernard Delperier,Jacques Thebault,Jean-Marie Toussaint +4 more
- 09 Apr 1996
TL;DR: In this paper, the infiltration conditions are changed between the start and the end of a chemical vapour infiltration process by varying at least one of the infiltration parameters, i.e. the dwell time of the gas phase, the pressure, the temperature, the precursor content of the gaseous phase, and the optional dopant content.

Patent
Composite material with multiple interphases between refractory reinforcing fibers and ceramic matrix
Cotteret Jacques,Jean-Philippe Rocher,Louis Heraud,Jacques Thebault,Roger Naslain +4 more
- 05 Jan 1990
TL;DR: In this paper, a layer (16) forming interphase in a material having a lamellar structure is situated between the fibers of the texture and the matrix, and at least one layer (14) forming control interphase is situated in such a way as to define, for those cracks which have spread through the matrix (18), a preferential propagation zone away from direct contact with the actual fibers (10).
