Repair of damaged aerospace composite structures

Common manufacturing defects include anomalies such as porosity, microcracking and delamination resulting from processing discrepancies as well as inadvertent edge

During the manufacture of a new aircraft, FAR Part 121.707 -Alteration and repair reports requires die airframe manufacturer to keep a copy of each report of a major repair available for inspection. Airplane operators therefore require a record of major pre-delivery repairs. For economic and logistical reasons they have a need to know about any pre-delivery repairs that will affect their maintenance operations. In response to these customer requirements, original equipment manufacturers (OEMs) compile a Significant Rework Log for each airplane and deliver it with the airplane. Rework/repair is deemed significant when it may have an impact on the way the airplane operator will perform repair, maintenance, or overhaul, or affect the inspection program that the airplane operator must follow. 

The main characteristic of in-service damage is that it occurs during service in a random manner. A list of sources of in-service damage threats is given below  

For damage sustained to aircraft structural composite materials, the repair methodology depends on the size of the damage and other factors. An aircraft s Structural
