AGARD-R-716, ADVISORY GROUP FOR AEROSPACE RESEARCH & DEVELOPMENT (AGARD) REPORT: COMPOSITE STRUCTURE REPAIR (14-OCT-1983)., The technology for advanced composite structure repair is presently in a developing stage. The boundaries avid limitations of bolted versus bonded repairs and precured patches versus cocured in place patches 3nd their applicability to various types of hardware has yet to be clearly established,. This paper does not discuss step by step repair procedures for specific air- craft components, such as defined in repair technical crders, but rather provides general guidelines for repair concepts and discusses two repair configurations that are generic in nature; an external patch and a near flush repair and the extent to which they have been verified in the US. These repairs are applicable to a wide variety of light to moderately bonded (up to 25,000 lb/inch) stiffened and honeycomb sandwich structure sustaining damage over a reasonably large area (up to 100 sq. in.). Also provided are references to documents containing step by step procedures for these repair techniques and identification of organizations in the US. actively engaged in advinced composite structure repairs.
