Quick Carbon Fibre Question

[Mark One]

With reference to prepreg carbon manufacture:

Does the autoclave supply the 1bar (or so) pressure required when curing or is that supplied by the vacuum bagging around the part?

Cheers,
Mark

im pretty sure the bag sucks the air out pulling the pre preg down on to the mold, the auto clave is just an oven, gets to a temp which makes a chemical reaction happen in the pre preg making it harden....

Supplied by the bagging IIRC.

OT: Are you from brookes?

 

[Fred@BTM]

depends on the material, the complexity, the thickness etc etc

the clave is a pressure oven, but can be used as just an oven

bagging helps the resin settle uniformly IIRC

[Fred@BTM]

if i could find my old coursework i'd quote it for you, but f**k knows where it is!

Pre peg is when the CF already has a leayer of resin wetted on, no?

Is this one for the 2nd year material lab? None of the FS team around to quiz their knowledge?
