Autoclave



DLR-BT in Stuttgart has a hot-air autoclave facility for producing complex, near-net-shape C/C preforms (carbon fibre-reinforced carbon). The C-containing preforms are converted into ceramic matrix composites (CMC) in subsequent process steps.

 

Technical data:

Inner diamter 1200 mm
Cylindrical length 2750 mm
Operating temperature 350°C; zukünftig auch 400°C (max. 4K/min)
Operating medium Heißluft; zukünftig auch Stickstoff
Operating pressure 20 bar
Vacuum under film bag Pabs = 0,1 bar

 

Application:

Mainly, prepreg technology is used. The high pressure inside is used to compress the individual laminate layers with the help of a vacuum film bag in which the preform is located. A defined pressure, vacuum and temperature profile is applied to cure the fibre composite.
