The main objective of the course is to impart an understanding of the manufacturing science and engineering of non-metals which is usually not covered at theUG level. The course deals with the study of the basic nature of different non-metals and the manufacturing processes associated thereof. The various non-metals covered in the course include glasses, ceramics, plastics and different types of composite materials.

Contents: Introduction; classification of engineering materials and processing techniques, various types of non-metals, basic nature of non-metals, properties of various non-metals, challenges in processing of non-metals, glass forming, heat treating glass; classification of ceramics, structure and properties, synthesis of ceramic powders, processing of ceramic products, ceramic coatings.

Classification of plastics, processing – injection/rotational/blow molding, extrusion, thermoforming, rapid prototyping; classification of composite materials, polymer matrix composites, processing – hand layup, filament winding, pultrusion etc., processing of ceramic matrix composites, Secondary processing of composite materials.
