Granddaughter Alyssa and I are involved in vacuum bagging processes:
carbon fiber spar caps, fiberglass over foam flying surfaces, and a
molded all glass fuselage pod and boom.
We're using West System 105/206 for all of the components.
We know that post curing - higher than room temperature heat over
several hours to a full day - will make the epoxy matrix stronger,
but after a long web search have been unable to get firm numbers for
either the temperature required or the recommended time period.
If anyone can pass on this information, we'd very much appreciate it.
We have our "hot box" made and can take it up to 160 degrees F.
Many thanks in advance!
