VACUUM BAGGING



From solid glass lay ups to complex composite structures, vacuum bagging is a technique that should, and can, be explored by even the novice.

The principle behind vacuum bagging is that of using atmospheric pressure as a tool. At sea level, one atmosphere weighs 14.7 psi (pounds per square inch) or 29.92 inches of mercury. In the absence of a vacuum, a surface has atmospheric pressure exerted on all sides and is equal. When a vacuum is generated on one side only, the result is an increase of pressure on the other side equal to the amount of vacuum being generated. A one square foot area is receiving 2,116.8 ponds of pressure with a 29.92" Hg vacuum beneath it.

Make sure all materials are compatible with the resin system, and that they can handle the cure temperature. Also remember that oven or autoclave temperatures will likely approach 375-400 F during a 350 F cure bagging materials must be compatible with these higher temperatures.
