SAE ARP 5089 Composite Repair Non-Destructive Testing (NTD) / Non-Destructive Inspection (NTI) Manual

Developed by the Society of Automotive Engineers (SAE), the SAE ARP 5089 standard provides basic information on the design, implementation, repair and inspection of composite structures, including metal bonding, used in civil transport aircraft.

The purpose of this standard is to help inspectors to know where the composite and metal bonded parts will be in the aircraft, to understand the capabilities of existing non-destructive testing methods, and to interpret the inspection results. This standard does not contain audit procedures, it is intended to be informative only and is not used alone. In other words, it does not invalidate any instruction contained in the documents of a manufacturer or operator.

In general, composite repairs are performed on damaged laminate structures, fiber reinforced composites and other composite materials. Composite repair reduces stresses in the damaged area and prevents cracks from opening or growing. Composite materials are used in a wide variety of applications in the aerospace, marine, automotive, land transport and sporting goods fields.

Damage to composite components is not always visible to the naked eye, and the extent of damage is best determined by appropriate non-destructive testing (NDT) or non-destructive testing (NDI) methods for structural components.

Automakers use composite plastics such as carbon fiber, fiberglass and sheet molded compound in vehicle construction. In the event of a failure, repair adhesives specially formulated for composites now allow technicians to repair a small, damaged area on the panels instead of replacing the entire part. These adhesives offer advantages such as lightness, bonding to different materials, aesthetics and reduction of noise, vibration and stiffness. It also creates a strong, if not stronger, bond than rivets and welds.

First, the type of repair required must be determined. Structural repair, any cracking of the plastic, i.e. anything that spoils the composite behind the actual surface requires a real repair.

Among the numerous test, measurement, analysis and evaluation studies it provides for businesses in various sectors, our company also provides composite repair non-destructive testing (NTD) / non-destructive testing (NTI) testing services within the scope of SAE ARP 5089 standard, with its trained and expert staff and advanced technological equipment. gives.
