Guest Ponyfreak Posted September 8, 2005 Report Share Posted September 8, 2005 Buy the west systems resin. "Buy it now" through ebay offers the best price. Buying from a local vender will cost an arm and a leg. I cannot remmber what number I used on the resin, but I used the slow hardener and am glad I did. Unless you have small pieces i would opt for the slow hardener. Quote Link to comment Share on other sites More sharing options...

Guest Ponyfreak Posted September 8, 2005 Report Share Posted September 8, 2005 Ebay has a lot of CF at decent prices. You must have a vacuum and vacuum bags before you think about laying down CF. it is a pain in the ass Quote Link to comment Share on other sites More sharing options...

Science Abuse Posted September 8, 2005 Author Report Share Posted September 8, 2005 ebay amen. Vaccume bags are neccesary? It cant be laid like fiberglass? Quote Link to comment Share on other sites More sharing options...
Mallard Posted September 8, 2005 Report Share Posted September 8, 2005 ebay amen. Vaccume bags are neccesary? It cant be laid like fiberglass? yes it can be laid like fiberglass without a vaccuum bag. Depends on what you're making though. Quote Link to comment Share on other sites More sharing options...
Science Abuse Posted September 8, 2005 Author Report Share Posted September 8, 2005 Like a core support? Nothing pretty, just light and able to hold headlights, and channel air into the radiator. Quote Link to comment Share on other sites More sharing options...
Mallard Posted September 8, 2005 Report Share Posted September 8, 2005 If it's not structural you should have no worries. All the CF on our Formula SAE car was wet lay-up. Quote Link to comment Share on other sites More sharing options...
Science Abuse Posted September 9, 2005 Author Report Share Posted September 9, 2005 hmm, define structural? Headlights and such will be mounted to it. What does the vacume bag do, just help the resin permiate the fiber? I'm going to have to lay this over a mould, can the mold be bagged up with it?

Mallard Posted September 9, 2005 Report Share Posted September 9, 2005 Structural as in it's not something that's holding the car together and that could mean your life if it failed. Vaccuum bagging will get all the air bubbles out and keep the carbon dense (no ripples or air bubbles after it cures.) Other advantages would have to be researched because I haven't worked with it that much. All the tubs/cars I know of made out of CF are vaccuum bagged and cured under high heat in a pressurised oven (autoclave). I wouldn't make anything structural without those means since the end result depends so heavily on the process you use and how controlled it is. For our car we made bodywork, seats, dashes, radiator support and shrouds, etc. Quote Link to comment Share on other sites More sharing options...
Guest Ponyfreak Posted September 9, 2005 Report Share Posted September 9, 2005 Wet laying leaves a LOT of extra resin behind, which really increases the weight of the part. Vacum bags and a vac pump are not that expensive and definatly make all the difference in the world as far as weight and appearance. IMO.

recklessOP Posted September 9, 2005 Report Share Posted September 9, 2005 All the tubs/cars I know of made out of CF are vaccuum bagged and cured under high heat in a pressurised oven (autoclave). an autoclave isn't a requirement. take a look at the toyota eagle GTP...

Science Abuse Posted September 23, 2005 Author Report Share Posted September 23, 2005 ok, got the fabric and epoxy, what do I use to keep it from sticking to the mold/vaccum bag et al? Quote Link to comment Share on other sites More sharing options...
