Hello friends,
I participated in a seminar on manufacturing processes and in the process of wet layup with vacuum bag the instructor told us that in the laminate we have the right time to apply the vacuum and the last moment to apply the vacuum.
He stated the following information:
• EARLIEST TIME TO APPLY VACCUM - 100,000 CPS
• LATEST TIME TO APPLY VACUUM - 500,000 CPS
This is based on curve the viscosity increase x time.
All this so as not to have excessive removal of resin generating dry areas.
Does anyone use this method, does that statement apply?
