Skin-to-core bond line mapping system and method

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).

Dependencies are inferred from the claim text.
