A unidirectional continuous fiber composite is to be made from T300 graphite fibers in a HM epoxy matrix, and the composite is to have a longitudinal CTE of zero. Using the fiber and matrix properties in Tables 3.1 and 3.2, determine the required fiber-volume fraction. Is this a practical composite? Sketch a graph showing the longitudinal CTE of the composite versus the fiber-volume fraction, and show the range of fiber-volume fractions over which the longitudinal CTE would be negative.
