Unformatted text preview: Chapter 7: Polymer Composites Chapter 7: Polymer Composites KEY CONCEPTS KEY CONCEPTS (Note the application of key concepts from previous chapters (Note the application of key concepts from previous chapters in the present discussion) in the present discussion) • What are polymer composites? What are their unique properties What are polymer composites? What are their unique properties (high strength (high strength-high toughness) high toughness) ? What is their composition ? What is their composition (polymer (polymer matrix; reinforcements matrix; reinforcements – particles, long and short fibers) ? particles, long and short fibers) ? • How are polymer composites fabricated How are polymer composites fabricated (polymer matrices (polymer matrices – thermosets or thermoplastics impregnated with particles/long & s thermosets or thermoplastics impregnated with particles/long & s hort hort fibers; fibers; “wet wet ”, , “shape shape ”, , “set set ”) ? What factors affect ? What factors affect fabrication/processing conditions fabrication/processing conditions (complex processing , pressure, temperature and time dependent; viscosity and capillary action – key design parameters ) ? What are broad polymer processing categories ? What are broad polymer processing categories (mix (mix-shape shape-set; shape set; shape-inject inject-set; prepreg set; prepreg-shape shape-set)?...
