1. Objectives of Studying Composite Materials (1) to understand the manufacturing processes of reinforcement fibers and matrices for composites, (2) to understand the concept of tailored design philosophy (3) to extend a knowledge of applications and selection of different composites in consideration of the properties and characteristics. (4) to improve communication skills in english about engineering and technology.

2. Outcomes Upon completion of the course students should understand: Individual constituents in composites, The role of interface between the components, The consequences of joining fiber and matrix to form a unit, The consequences of joining together these unit to form a macro composites Design procedure with composits

3. I.Introduction Engineering Concept of Composite Materials 1. To be Manufactured 2. To consist of two or more physically and/or chemically distinct, suitably arranged or distributed phases with an interface separating them. 3. To have the characteristics that are not depicted by any of the components in isolation.

4. General Advantage of Composites 1.High Specific Strength( 4 to 6 times of Al, Steels) 2.High Specific Modulus(3.5 to 5 times of Al, Steel) 3.High Fatigue endurance limit that metals 4. High Toughness and High impact energy 5.Greater Design Flexibity because of custom tailored property 6.High Corrosion Resistance

5. High Cost Lack of well defined and easy to employ design rules Lack of high productivity manufacturing methods Environmentally Malign General Disadvantage of Composites
