NDI Survey of Composite Structures.
Abstract
As part of the Naval Air Systems Command Maintenance Technology Program, a survey was made of DoD, NASA, NBS, Industry and the R&D Community reviewing and analyzing the current status of current nondestruction inspection (NDI) technology for composites. The survey is aimed at contributing information which will assist in defining NDI requirements for the organizational, intermediate, and depot levels of maintenance. The investigation reported herein covers a survey to determine the state of NDI technology for composite materials and an analysis of the survey results in terms of maintenance requirements for naval aircraft. This review and analysis of the status of current NDI technology covers the experience of DoD, NASA, NBS, Industry, and the R&D community. A range of composite materials and constructions, damage classification, repair procedures, and NDI techniques were included in the survey. Twenty-one different NDI methods were examined and ranked in terms of effectiveness. Twelve types of composited damage and five different repairs were considered during the investigation. Conclusions included definitions of the most frequently encountered types of construction, the five NDI techniques considered essential, specific technique recommendations for specified damage to specified configurations, and technique recommendations for verifying specific types of repairs.
