Procedure for Application of Boron-Fibre Reinforced Plastic Patch to the Mirage Lower Wing Skin Fuel Decant Region.

Abstract

Aeronautical Research Laboratories have developed a new procedure for the repair of metallic aircraft components suffering from cracking due to fatigue or stress-corrosion; the procedure is based on the use of patches made from Boron-Fibre Reinforced Plastic which are adhesively bonded over the crack region. Crack patching using this technique has been successfully used in a number of repair applications on RAAF aircraft since 1975, and has been shown to be highly cost effective and also to have many other advantages over standard repair procedures. More recently, a 'crack patching' procedure was developed by ARL to repair fatigue cracks which have developed in the lower wing skins of some RAAF Mirage aircraft. Since this was a much more critical and complex application than any previously undertaken, involving the use of specially developed ground support equipment, a detailed specification was written as a guide for RAAF personnel, who were trained to implement the repair; this specification is presented in this Memorandum.
