Develop knowledge related to basic materials constituents and mechanics of composite materials including micromechanics and classical lamination theory. Participants learn about design and analysis of composite structures, and composite manufacturing processing.
- General introduction, characteristics, comparison to metals, fiber types, resin types, and fabrics.
- Manufacturing and processing, differences between thermosets and thermoplastics, overview of processing methods, cure kinetics and consolidation.
- Micromechanical aspects, mass fraction and volume fraction, density, rules of mixture for elastic properties, use of PROMAL (computer program).
- Micromechanical aspects (continued), moisture uptake and effects, coefficients of thermal expansion, hygrothermal effects, glass transition temperature, combined effects of stress and moisture.
- Strength characteristics, failure modes, unidirectional tension and compression tests and comparison with experiments, simple design examples.
- Lamina characteristics, off-axis effects, elastic constants of a lamina, relation between stress and strain, simple design examples.
- Strength criteria and theories, maximum strength, maximum strain, Tsai Hill, Tsai Wu, failure envelopes, simple design examples.
- Laminates, laminate code and stacking sequence, special effects, ABD matrix, simple analysis examples.
- Laminate analysis, laminate examples, hygrothermal effects, failure modes and criteria.
- Simple design examples, beams, sandwich beams.
- Design allowables, A-basis and B-basis, strain limitations, concepts of durability and damage tolerance.
- Quality control and standards, raw material level, composite level, introduction to Mil-HDBK 17.
