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.
