Vacuum bagging and vacuum bagging supplies

Vacuum bagging is a crucial process to achieving the best and strongest finish in composite projects. Experts and mass-producers know the benefits  and intricacies of vacuum bagging but for the uninitiated, vacuum bagging is the method of using a vacuum to extract air and compress layers of composite materials during the curing process. The process also cuts down on factors which can affect the cure and finish, such as humidity, and helps create a uniform, strong and even surface finish while minimising the amount of binding resin required.

The vacuum bagging method requires the fabric, epoxy and mold to be contained within a sealed plastic film. A vacuum extracts the air from within that plastic film and the pressure created by the vacuum ensures even and absolute distribution of resin throughout the fabric while also compressing the composite materials to the mould shape.

If, for example, you were making a surfboard you could use a fibreglass vacuum bagging technique to make the board conform to the mold or blank. Vacuum pressure pushes epoxy through the fibreglass fabric and helps create strength without weight. Vacuum bagging is also a way to achieve a tight, even bond when adding design or structural features to a board.
