Outline Special features of advanced composites/mechanical implications

Review of classical lamination theory

Manufacturing of composites

Specimen preparation

Microstructural characterization

Thermo-mechanical analysis

Tensile, compressive, sheat, and flexure testing

Fatigue testing

Interlaminar fracture testing

Methods of non-destructive evaluation

Acoustic emission and acousto-ultrasonics

Ultrasonic scanning and acoustic microscopy

 

General Format This laboratory course will introduce students to a number of modern

experimental techniques for compreshensive experimental characterization

of advanced polymer fiber reinforces composites. It will provide hands-on

experience with the state-of-the-art experimental systems for composite

manufacturing,, thermo-mechanical analysis, mechanical testing, and non-

destructive evaluation. Roughly, 1/2 of the time will be devoted to

lectures and 1/2 to laboratory sessions utilizing leading edge experimental

equipment.

 

Schedule There will be seven individual experimental miniprojects and a final exam

 

Grading Miniprojects @ 20 pts 140

Final 60

Total 200 points
