JAWAHARLAL NEHRU TECHNOLOGICAL UNIVERSITY HYDERABAD

Course Objective

The prime objective of this course is to introduce, classify, and process

composite materials which are novel and widely applied materials. The applications of composite materials that would suit the requirements are also dealt in detail as an integral part.

Course Outcome

The student will apply the concepts learnt during the course to design, and

apply a composite material for a specific application.

UNIT - I

Introduction: Definition – Classification of Composite materials based on structure and matrix. Advantages and disadvantages application of composites based on structure – Functional requirements of reinforcement and matrix. Effect of reinforcement (size, shape, distribution, volume fraction) on overall composite performance.

UNIT - II

Reinforcements: Preparation, properties and applications of glass fibers, carbon fibers, Kevlar fibers and Boron fibers. Properties and applications of whiskers, particle reinforcements.
