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).

A composite cylindrical wall is composed of 2 materials of
thermal conductivity ka = 240 W/mK and kb = 20 W/mK, where
interfacial contact resistance is negligible.
- Liquid pumped through the tube is at a temperature Tinf, i =
200 F and provides a convection coefficient hi = 450 W/m^2K at the
inner surface of the composite pipe
-The outer surface is exposed to Tinf, o and provides a
convection coefficient of ho = 20 W/m^2K
-A thermocouple between...
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?
