Flgnre 5.3 Voids resulting in a composite laminate ftom dissolved moismre in the prepregs in an autoclaving process where vacuum bagging was used but no external pressure was applied. From Ref. [4]. 

Interface defects are largely caused by inadequate conditions for generating bonds at interfaces between fibres and matrix and between layers of composites during manufacturing. If resin is infused into a fibre preform, it may not wet the entire fibre
