This module is not approved as a discovery module
Objectives
On completion of this module, students should:- have gained insight into the structure of engineering materials;
- become familiar with structure-property relationships;
- have acquired initial insight into the role of materials in aircraft.
Learning outcomes
Students will gain knowledge and understanding of the structure and properties of metals, ceramics, polymers and composites.
They should have developed an ability to relate the structure and properties of materials to aerospace applications.
Skills outcomes
On completion of this module the students will be able to understand:
- the definition of physical properties of metals, ceramics, polymers and composites;
- their origin;
- the structure and property relationship;
- the calculation of properties from given information;
- how to apply the knowledge to aviation applications.
Other skills outcomes include Close Reading (Practiced and Assessed)
Students acquire the following competencies in the module. In each case, the means of acquiring the competency is shown. These competencies correspond with those specified in "The Accreditation of Higher Education Programmes", Third edition, Engineering Council, 2014. P = Practiced actively, F = Formatively assessed, S = Summatively assessed. Discussions refer to both open in-class discussions of questions from broad to highly focused and semi-structured discussion centred around numerous case studies.
SKILL SM1: HOW MANIFESTED: Students gain understanding of the physical science underlying metallic and non-metallic materials and how this impacts aircraft. P in laboratory sessions and tutorials, F in problem sheet and online formative assignment, S in examination.
SKILL SM3: HOW MANIFESTED: Students draw knowledge from materials science and engineering and apply this to selection and use of materials for aircraft, integrating the two. F in problem sheet (especially the materials selection activity). S in examination.
SKILL EA1: HOW MANIFESTED: Students gain insight into how the principles of e.g. stress and strain, corrosion and use these to analyse e.g. minimum yield strength required for an aircraft component, or suitable methods of preventing corrosion of a component. P in tutorials, F in problem sheet and online formative assignment, S in examination.
SKILL EA3: HOW MANIFESTED: Quantitative methods are applied e.g. in analysing stress and strain, diffusion etc (F in problem sheet and online formative assignment, S in examination). Computational methods are used for materials selection, using CES (F in problem sheet, which significance of the outcomes S in examination).
SKILL D3: HOW MANIFESTED: Students learn e.g. when an order of magnitude estimate of the diffusion distance is sufficient and when C(x,t) is required. P in tutorials, S in examination.
SKILL EP2: HOW MANIFESTED: Students gain basic knowledge of e.g. steels, thermosetting versus thermoplastic polymers, carbon fibre reinforced polymer composites, p and n type semiconductors. P in tutorials and especially the lab. S in examination.
SKILL EP3: HOW MANIFESTED: Students undertake laboratories on metallography and mechanical testing (P), with knowledge gained used in examination (S).
SKILL EP4: HOW MANIFESTED: Students are expected to read around the literature to develop their own examples. S in open-ended questions in examination.
SKILL EP8: HOW MANIFESTED: Students learn about the need for safety margins, in response to uncertainty about the service conditions that aircraft experience and how to build these into materials calculations. P in tutorials, F in problem sheet and online formative assignment, S in examination.
SKILL AGS1: HOW MANIFESTED: Students undertake a range of problem solving activities. F in problem sheet and online formative assignment. Effects of this are apparent (S) in examination.
