Composite Systems (Metal, Ceramic, Polymer) - AEM-CM08
• To introduce the development of ceramic matrix composites (CMCs)
• To present the different polycrystalline ceramic and silicate glass matrix available for CMCs
• To consider relevant process technologies for reliable production of CMCs
• To enhance understanding of the structure and mechanical properties of CMCs by considering particle and fibre reinforced composites, toughening mechanisms, failure behaviour and high-temperature behaviour, including thermal shock.
• To illustrate application of ceramic matrix composite materials with selected examples of commercially available composites.
• To address limitations of available CMCs.
• To introduce the variety and typical applications of metal matrix composites (MMCs)
• To deliver an overview of MMC technologies; benefits and limitations,
• To consider processing methods for different MMCs and factors affecting their manufacture.
• To review typical behaviours and failure modes of the main MMC classes.
• To introduce polymer-basics: chemistry, physics, classification, structure, molecular weight (distribution).
• To present the difference between: a) chain growth & step growth polymerisation, b) amorphous & semi-crystalline polymers, c) thermoplasts & cross-linked polymers.
• To present polymer properties: thermal (melting temperature, glass transition temperature), crystallinity: dependency on structure.
• To illustrate mechanical properties: stress-strain behaviour, Young`s modulus.
• To introduce viscoelasticity: models, time-temperature-superposition.
• To address an example of polymer-matrix-composite.
