1a. Spheroidite steel is a good example of Metal Matrix
Composite material. What are the matrix material and the dispersed
phase acting as a reinforcing agent?
1b. Name one material that is commonly used as the fibers in
fiber reinforced composites.
2a. In metals increasing “imperfections” e.g. grain boundaries,
dislocations, vacancies in the material will increase or decrease
the resistivity of that material? Briefly explain why.
2b. Does the resistivity of a copper increase or decrease when
it is heated...

Composite materials often times consist of fibers imbedded in a matrix material. What role does the fiber length, fiber orientation and fiber and matrix clastic properties play in determining the mechanical properties of the composite?
Do some internet research on the properties of composite
materials. a) Compare the tensile strength of a typical
glass fibre reinforced polymer with the tensile strength of a
carbon fibre reinforced polymer. Make sure you the fibre lay-up is
the same in your two examples and that you record what that is in
your answer. Use data tables from reputable engineering or
scientific web pages or material suppliers only and cite your
reference(s).

Summarize, compare, and contrast the various theories that
explain the shape of the term structure of interest rates. Which
theory is most reasonable? What do researchers, academics, and
practitioners, think about these various theories? Please support
your answer with appropriate research.
