Porosity Assessment in Large Composite Components: Realization and Challenges

摘要

Non Destructive Inspection (NDI) of large Out of Autoclave Cure primary monolithic and sandwich Composite structures is challenging due to high requirement for flaw detection and characterization among porosity, delamination, disbond, foreign material, crushed core, dry fiber. Large scale NDI inspection with semi-automated and automated system is presented for flaw detection/characterization and porosity assessment methodology is described with results for high porosity level assessment in monolithic and sandwich structures.
