Topic outline

  • Learning outcome:

    Classification of composites and lightweights materials,aavanced inspection of composite structure damages, and selcetion of suitable inspection methods.

    Competences

    • To differentiate between the different typologies and shapes of composite materials.
    • To carry out all inspection processes – search, detect and diagnose of structural failures.
    • To assess, estimate and classify damages for determination for further repairing process according to the working conditions.
    • To be able to give clearance after a routine check or composite changes (ex. birds strike, cracks, hits, lightening, corrosion etc.)

    Knowledge

    • To know basic lightweights and composite materials properties.
    • To know the composite materials technologies (composition, types, properties, application…)
    • To know the damages types and resources of composite structures.
    • To know the basic Non-Destructive Testing methods and application.

    Skills

    • To determine the lightweights and composite materials properties, that required for the inspection process.
    • To follow instructions provided by approved technical documentation.
    • To navigate in the composite manual
    • To follow instruction in using the Non-Destructive-Test techniques (NDT) and assessment of their strengths and weaknesses.
