Repeat Problem 11.18 for 35% carbon fibers by volume.

Repeat Problem 11.18 under isostress condition.

An aligned and continuous fiber reinforced composite consists of fibers

with an elastic modulus of 290 GPa and a matrix with an elastic modulus of

3.5 GPa. If the fibers are required to carry 92% of the total load in the longitudinal direction (isostrain condition), determine the volume fraction of the fibers and matrix needed to accomplish this task. Also, determine the composite

modulus of elasticity for this case.
