This module gives the student a foundation in the application of biomaterials in medical devices. The student is given a broad introduction to plastics, ceramics and in depth delivery on composites materials. It also aims to provide the student with further understanding of the relationship between microstructure and associated properties of polymer bio-materials, modelling of plastics using mechanical models, and use of creep curves.
