Abstract: A skin-to-core bond line mapping system and method is disclosed. Layered composite components formed by “sandwiching” multiple materials together require a continuous bond between those materials with voids below particular thresholds that can vary by application. The skin-to-core bond line mapping system can include a laminate, an adhesive, a separator film, a core, a breather, a layup tool, bagging material, sealant, and a vacuum port. By employing systems and processes that layer separator film over adhesive and applying a core proximate the adhesive, a bagging material can be disposed over the materials to facilitate vacuum compaction, thereby impressing core impressions on the adhesive to map the areas between the skin and core that have good contact. An iterative process is disclosed, in which additional adhesive can be used to build the bond line until contact is made (or engineering tolerance is reached).

Abstract: Methods and apparatus to form venting pathways in pressure sensitive adhesives for laminate stacks are disclosed. An example method includes forming a laminate stack including a gas permeable nonwoven layer and a pressure sensitive adhesive layer. The pressure sensitive adhesive layer has a first surface and a second surface located opposite the first surface. The first surface contacts the gas permeable nonwoven layer. The method further includes processing the laminate stack by reducing a ductility of the pressure sensitive adhesive layer such that venting pathways are formed in the pressure sensitive adhesive layer in response to a mechanical strain applied to the pressure sensitive adhesive layer via a trapped gas. The venting pathways extend through a thickness of the pressure sensitive adhesive layer to enable the trapped gas to pass through the pressure sensitive adhesive layer from the second surface to the first surface.
