Bonded repair of metallic aircraft structure is used to extend the life of flawed or under-designed components at reasonable cost. Composite repairs. External patches are usually stepped to reduce the stress concentration at the edge of the patch. Composite doublers or repair patches provide an innovative repair technique which can enhance the way in which aircraft are maintained. Commercial aircraft manufacturers are also beginning to use composites in structural applications where reduced structural weight leads to significant fuel savings. After assessing all the damage, repairing a composite structure usually means greater downtime because of the cure times resins and adhesives require. The bonded repair … title = "Advances in the Bonded Composite Repair of Metallic Aircraft Structure", abstract = "The availability of efficient and cost-effective technologies to repair or extend the life of aging military airframes is becoming a critical requirement in most countries around the world, as new aircraft becoming prohibitively expensive and defence budgets shrink. The FAA Advisory on Composite Aircraft Structure52 includes guidance for bonded joints in primary composite structure and therefore critical repairs where failure of the joint (or repair) would result in failure of the structure. From minor repairs to complete rebuilds, we have the qualifications and experience to return parts to service quickly and at fair, competitive prices. Working with aircraft that feature not only more composite structures, but larger, more integrated and increasingly complex composite structures, major airlines and MRO providers foresee several challenges. Some of the criteria set forth by the OEMs include inspecting the repair for proper curing of the resin, complete bonding between the repair and the structure, voids or porosity in the repair, and evidence of correct resin content. composite structures can be maintained and repaired if damaged. Advanced composite structure was first introduced on military aircraft when the reduced weight was desired for improved tactical performance. Furthermore, now that composites have permeated primary aircraft structures — i.e. Aircraft radomes are made of at least 10 plies of Kevlar.
