Module Description: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.
Learning Outcomes
On successful completion of this module the learner will be able to:
LO1 Describe the structure, composition and bio-compatibility of commonly used bio-materials
LO2 Describe the different bio-polymer systems, effects of crystallinity, mechanical properties, long & short term testing, design methods used for plastics.
LO3 Distinguish different types of composite structures & materials, application of rule of mixtures. Design using models for predicting various properties of composites used in the manufacture of medical implants.
LO4 Describe the deformation processes and relate structure of materials to their properties
LO5 Report and analyses experimental results of the following labs: strain rate testing of polymers; composite properties & heat treatment of steels
LO6 Describe the regulations governing the production and use of biomaterials
