Course Objectives
- Students will get some fundamental knowledge on the commonly used Composite Materials for various types of applications.
Course Outcomes
1. Students will learn about various constituents that are commonly employed to fabricate structural composites. <br />2. Students will learn the importance of interfaces and their impact on the overall performance of the Composite Materials. <br />3. Students will be able to predict some physical properties of composites and also the strength of several composite materials based on the configuration of composites and the state of loading. <br />4. Students will be able to differentiate the properties and performances of various Composite Materials and hence can choose a particular one based on the application requirements.
