16.16  It  is  desired  to  produce  an  aligned  carbon fiber–epoxy matrix composite having a lon- gitudinal tensile strength of 500 MPa (72,500 psi). Calculate the volume fraction of fibers necessary  if  (1)  the  average  fiber  diameter and length are 0.01 mm (3.9 x 10-4  in.) and
0.5  mm  (2 x 10-2  in.), respectively; (2)  the fiber fracture strength is 4.0 GPa (5.8 x 105 psi);  (3)  the  fiber–matrix  bond  strength  is 25 MPa (3625 psi); and (4) the matrix stress at composite failure is 7.0 MPa (1,000 psi).
