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:
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.
