Problem 1. You have glass fibers and a thermosetting plastic, sketch three different ways in which they could be arranged to give you formats with different strength. Of the three you drew, which is most isotropic and which is most anisotropic and why?

Problem 2. Explain the basic components required to make a composite and explain the role of each component.

Problem 3. Give two benefits of composites over metals and one area where they fall short of metals.

Problem 4. List two reinforcement materials and two matrix materials.

Problem 5. Draw a stress-stain curve for a brittle polymer, a ductile polymer, and an elastomer. Comment on their expected behavior in the elastic region of their curves. Be sure to name relevant material properties in your commentary.

Problem 6: Explain how changes in temperature can impact the behavior of a polymer.

Problem 7: a) Draw a diagram showing the polymer delivery system from beginning to mold for an injection molding process. (Remember that the equipment it is similar to extrusion with one exception) b) List and explain the process stages.

Problem 8: List 3 properties of engineering ceramics and applications in which these properties are advantageous.
