This unit of learning is part of the following learning pathways:
Readings:
- Learning outcome:
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.
- To differentiate between the different typologies and shapes of composite materials.
