Engineering Practice 1 - AERO40004
Engineering practice involves more than the application of theory and utilising mathematics to solve problems. It requires engineers to have an awareness of practical, legal, ethical and manufacturing constraints, to be creative in proposing solutions to problems, and be able to communicate, collaborate, plan and manage their work. This module offers a first opportunity to engage in engineering practice, while supported by a range of workshops, lectures and tutorials.
Advanced Manufacturing - AERO96020
The aim of this module is to introduce the manufacturing processes of composite materials and their corresponding underlying manufacturing principles to provide a deeper understanding of the relationship between design, manufacturing processing and materials properties. This module discusses basic transport equations and constitutive laws used in composite processing, followed by detailed quantitative/qualitative discussion and analytical analysis of polymer matrix, metal matrix and ceramic matrix composite manufacturing. Various composite manufacturing methods are discussed, including short polymer fibre composites, advanced thermoplastic composites, advanced thermoset composites, melt metallurgical processes, powder metallurgical processes, advanced hybrid fibre metal laminates and ceramic matrix composite manufacturing route via melt infiltration, chemical vapour infiltration and polymer impregnation and pyrolysis processes. The real life applications of each manufacturing processes are also covered in this module. The module will consist of timetabled lectures deliver by two academics with the relevant research expertise.
Introductory Mathematics - AERO97028
To revise essential Mathematics over 10 lectures that is necessary for the MSc.
