Affective (Attitudes and Values)
- Students will appreciate damage tolerance of composite aerospace structures and its importance in structural design philosophies: fail-safe versus safe-life
- Students will demonstrate their ability to design composite structural elements to deal with a variety of loading scenarios using a holistic approach to material selection, manufacturing considerations and structural analysis (written exam)
- Students will build confidence in utilizing solid mechanics theory equations for the analysis of real composite structures (written exam)
Psychomotor (Physical Skills)
- Students will be able to work within a team to produce a composite laminates and structural components (laboratory work)
How the Module will be Taught and what will be the Learning Experiences of the Students:
Lectures, tutorials and laboratory exercises will be used for the students to acquire the learning outcomes. Leading edge aerospace composite structures research will be embedded in the syllabus, particularly in relation to new inspection and material processing developments, to enhance the student experience. UL has significant experience in this field of research.
The module is aligned to the following UL graduate attributes:
Knowledgeable: Students will apply their materials and mechanics of solids knowledge to structural analysis of fibre-reinforced composite components.
Proactive/Creative: Students will design innovative composite components to meet an assignment specification to be manufactured as part of laboratory activity.
Responsible/Collaborative: Laboratory design and practical work will be carried out as part of a design team. Each team member is responsible for contributing to the team design goal to ensure that assessment targets are met.
Articulate: Design team members will be required to communicate effectively with one another to achieve their team goals. Output from the team laboratory activity will be disseminated in a jointly written report, requiring effective written input from each team member.
