Indicative Contents

المحتويات الإرشادية

Indicative content includes the following.

Part A – Polymeric materials and their additives

Thermoplastics, thermosets, and elastomers. Polymer additives: Fillers and reinforcements, plasticizers, and other important additives. Thermal transition in polymers: glass transition temperature Tg and melting point Tm, non-equilibrium features of glassy polymers and physical ageing, factors affecting Tg, relation between Tm and Tg, the free-volume theory, the WLF equation.  [50 hrs]

Part B – Processing of polymers

Viscosity of fluids and polymer melts. Basic processing operations: Extrusion process (Single and twin-screw extruder), Injection moulding, Blow moulding (extrusion blow moulding, injection blow moulding, and stretch blow moulding), Mould and dies, Calendaring, Film blowing, Thermoforming, Vacuum forming, Pressure forming, plug assist forming, draw forming, Free forming, Drape forming, Snap-back forming, Matched die forming, Mechanical forming, Rotational moulding, Compression and transfer moulding, Reaction injection moulding. Composite material fabrication methods: (resin transfer moulding, spray up, hand lay-up, filament winding and fiber placement, pultrusion, sheet moulding compounds and dough moulding compounds),, applications of composites. Testing of Polymer: Tensile, flexural and impact test, abrasion, hardness, long term fracture tests, HDT/ Vicat softening point, stress cracking, dielectric strength. [50 hrs]

Learning and Teaching Strategies

استراتيجيات التعلم والتعليم

Strategies

The main strategy that will be adopted in delivering this module is to encourage students’ participation in the exercises, while at the same time refining and expanding their theoretical thinking. This will be achieved through classes, interactive tutorials and by considering types of simple experiments involving some sampling activities that are interesting to the students.

Note: Marks Decimal places above or below 0.5 will be rounded to the higher or lower full mark (for example a mark of 54.5 will be rounded to 55, whereas a mark of 54.4 will be rounded to 54. The University has a policy NOT to condone "near-pass fails" so the only adjustment to marks awarded by the original marker(s) will be the automatic rounding outlined above.
