To make students updated on the cutting edge research activities in Composite materials globally

To upskill the students for analyzing the strength criteria and predicting the properties and performance of the composite structures under different types of mechanical loads along different directions

1. The students will be able to recognize different types of composite materials, reinforcements and matrices and the spectrum of their Engineering applications and limitations.
2. Students should be able to understand the basic characteristics and manufacturing of the reinforcements and matrices and realize the scientific origin of interfaces in composite materials and their importance on the overall performance of the composite Materials.
3. Students should be able to analyze the effects of structure and types of constituents and their arrangement on the interfacial interaction and physical and mechanical behavior of the resulting composite materials.
4. Students should be able to understand the basic facts which are to be considered for manufacturing of different types composite materials.
