Mixtures of two different polymers belong to the class of
a) Explain why a two-phase system can form when mixing two
different polymers. Give two examples of morphology types that may
b) Show by example how the morphology of a blend influences the
macroscopic properties of the blend.
Find a materials
property plot of elastic modulus and density.
Identify a composite,
a polymer, and a metal with densities less than 3000
kg/m3 (Mg = 106 g) and the highest possible
elastic modulus. Provide an example of an engineering design that
might require this combination of material properties and explain
why those properties would be important. What design advantages
could a polymer offer over a metal even though the polymer has a
