Goals: 1) to understand the relationships between the composite material and its constituents (reinforcement and binder).

2) to design composite laminated materials for specified stiffness and strength.

3) to tailor laminated composites for prescribed loading conditions.



Description:

The course will cover design and analysis of composite material components. The emphasis will be on oriented fiber reinforced laminated composites.

For most of the course, the focus will be on the analysis of the mechanical properties and strength of laminated fibrous composites. To aid in the understanding and future use of the studied material, the students will be guided to develop their own analysis software (on PC). This tool will be developed step-by-step, as the course progresses, by every student, and will be used during the semester for the solution of homework problems. The last part of the course will be dedicated to design applications and case studies.



Topics: 1) Why composites? advantages and disadvantages

2) Manufacturing techniques

3) Fiber and matrix properties

4) Orthotropic lamina

5) Effect of orientation on the mechanical properties

6) Laminate stacking and properties

7) Strength and failure modes

8) Composite material software

9) Soft core laminates

10) The composite tube

11) Case studies (design of composite components)
