Abstract
This study considers the effect of pressure in the hand layup and vacuum bagging processes. Firstly, the layup method is considered. The use of rollers is common shop-floor practice, but the results presented suggest that rolling plies can lead to areas of trapped air in laminates, as visualised by laying up a ply on a glass plate. The bagging process, designed to remove air and aid consolidation is a further opportunity for introducing variability in manufacture. Using a pressure mapping system, common bagging defects such as bridging and wrinkling are examined in the context of their effect on part quality. It is shown that bag pressure is far from hydrostatic when these features are present.
