Development and Application of Adhesive Materials for Advanced Composite Bonding

Abstract

To meet the needs of large composite bonding for aircraft, development, comprehensive experimental and application of adhesive materials have been carried out. Development process, adhesive bonding performance, operability and batch production of parts of adhesives are presented in brief. Traditional metal structural adhesives are widely applied to composite bonding for military use and civil use. We have made some progresses in development of toughened cyanate film adhesive and toughened BMI film adhesive. Development of high temperature resistant adhesives such as polyimide adhesive will be an important investigation area. All kinds of adhesives with different heat-resistant and chemical compositions need to be developed to meet adhesive selections for various composite bonding.
