Assembly technologies using structural adhesion

OBJECTIVE :

This course covers with the basic multi-disciplinary knowledge regarding the implementation of structural adhesion technology.  The objective is to offer participants an overall understanding of the issues related to adhesion.

COURSE DURATION AND TIMETABLE :

The course lasts 5 days (30 hours) and includes 5 practical work sessions.

GENERAL APPROACH :

Structural adhesion is an assembly technology that, in order to be used, involves an integrated multidisciplinary team. The approach proposed as part of this training aims to cover all aspects:

  • materials and processes
  • mechanical analysis
  • implementation and testing

Implementation and testing are illustrated through the section on repairs.

PREREQUISITE :

Course level: Basic

This course is intended for technical and scientific/design staff or laboratory personnel. Basic knowledge of materials science and materials resistance is required.

(BAC + 2/3 level)

COURSE DIRECTOR(S) :

Eric PAROISSIEN:

Lecturer-Researcher in Aerospace Structures at ISAE-SUPAERO*  *Institut Supérieur de l’Aéronautique et de l’Espace or National Higher French Institute of Aeronautics and Space

Course co-facilitated by a team of research professors from CIRIMAT/INP-ENSIACET, ICA/ISAE-SUPAERO and ICA/Université Toulouse 3.

CONTENT :

  • Introduction to the general problems of adhesion
    • Theories of adhesion, classes of adhesives, installation of adhered joints, discussion
  • Synthesis of poly-epoxy
    • Primary components and formulation additives, epoxide-amine reactions, kinetic polymerization monitoring, discussion. Practical work on the synthesis of polyepoxy and characterization by FTIR and DSC
  • Amine-epoxy/metal interphases
    • Definition of interphases, formation of interphases, influences on the properties of adhered joints, discussion
  • Surface treatments
    • Non-exhaustive list of surface treatments, influence on adhesion and properties of adhered joints, discussion
  • Characterization of adhesion
    • Key parameters during adhesion tests, non-exhaustive list of adhesion tests, discussion. Practical work on the experimental measurement of adhesion
  • Mechanical behavior analysis
    • The aim is to understand the transfer of force to the connection. For this, the modeling principles are presented as well as EF analytical and semi-analytical resolution methods, enabling the observation of the distribution of adhesive stresses. The application to bolted/adhered hybrid assemblies is looked at. Many exercises are included
  • Mechanical testing
    • The objective is to present various standardized or non-standardized experimental tests used to characterize the mechanical behavior until adhered assemblies are fractured. A summary of mechanical behavior analysis, which provides input data for holding criteria, and mechanical tests
  • Real and virtual mechanical tests
    • Practical work: manufacturing a metallic test composite repaired with an adhered patch and statically testing it then comparing those results with the predictions from the analysis
  • Reparation issues
    • The aim is to look at patch repairs on metal and composite structures used in the aerospace industry. An overview of composite repairs on fuselage-type structures will be given
  • Introduction to testing
    • The aim is to demonstrate the capacity of the current testing resources to qualify the adhesion conformity and quality. This part is delivered as a practical work session on US testing and RX of test pieces repaired by adhered patches
