Calculate the fiber volume fraction, Physics

An engineer is using DSC to determine the fiber volume fraction of a carbon fiber / epoxy prepreg. It is known that the heat of reaction of the pure, fresh epoxy resin (no carbon fibers, no curing) is 525 J/g. The DSC response of a fresh sample of prepreg (no curing) is given below.

A) Calculate the fiber volume fraction of the prepreg.

B) From the DSC response can you determine if there is more than one type of curing agent? Explain why or why not.

3) One of the materials given below is a pure thermoplastic polymer while one is the same polymer with a filler. Given the viscosity data below, which one contains the filler? Briefly explain.

B) What is the zero shear viscosity values for the materials given above?

C) Is either material a Newtonian fluid under any conditions? Explain.
