Manufacturing Fin Can
1. Prepare Overwrap Materials
...
Do not exceed pot life of the epoxy → can’t be pulled out later
Ensure that the carbon fiber doesn’t bunch up / shift during layup
Use extra breather to prevent the vacuum connector from denting carbon fiber
Double check vacuum is connected correctly
Minimize wrinkles in all layers: release film, peel ply, etc.
Don’t use the foam technique near the fillets unless we know it’s gonna work
Make sure there is not a lot of excess carbon fiber near the fillet (needs to fit the profile pretty closely)
Cure at room temperature in low-temp vacuum bag for 24-36 hours
Oven cure for an additional 12 hours in high-temp vacuum bag
