Unit 1

Types of reinforcements, their mechanical properties and functions – ceramics, glass, carbon, boron, silicon carbide, metal, aramid. Forms of reinforcements – particulate, fibre, filaments, whiskers, flakes. Pre-fabricated forms – preforms, prepegs, fabrics, honeycomb.

Type of matrix, its mechanical properties and functions – polymers (thermosets and thermoplastics), metals, ceramics, glass and carbon. Basic principles in the design of composites and selection of matrix and reinforcement. Bonding mechanisms.

Unit 2

Anisotropic Behaviour and relationship between structure-mechanical properties.

Mechanical testing – tensile, compressive, Intra-laminar shear, Inter-laminar shear and fracture.

Polymer Matrix Composites: Types of thermoset and thermoplastic resins. Principles in the selection of matrix and the reinforcements. Process selection criteria. Mould and tool making. Basic manufacturing steps – impregnation, lay-up, consolidation and solidification.

Unit 3

Manufacturing processes for polymer composites – lay-up, compression moulding, extrusion, injection moulding, sheet forming, pultrusion, hot press & autoclave techniques and filament winding. Applications – industrial, automotive and aerospace.

Metal and ceramic matrix composites – wettability of reinforcement to matrix and bonding, methods of manufacturing reinforcements with intermediate wetting layer.

Manufacturing processes for metal matrix composites: casting methods – gravity & low pressure die, investment, squeeze, spray forming, compression moulding and thixo-moulding. Manufacturing processes for ceramic matrix composites: reaction sintering, electro-deposition, spray forming, infiltration. Applications – industrial, automotive and aerospace.
