Chapter 16: Problem 15
Compute the longitudinal strength of an aligned carbon fiber-epoxy matrix composite having a \(0.20\) volume fraction of fibers, assuming the following: (1) an average fiber diameter of \(6 \times 10^{-3} \mathrm{~mm}\left(2.4 \times 10^{-4}\right.\) in. \(),(2)\) an average fiber length of \(8.0 \mathrm{~mm}(0.31\) in. \(),(3)\) a fiber fracture strength of \(4.5\) GPa \(\left(6.5 \times 10^{5} \mathrm{psi}\right),(4)\) a fibermatrix bond strength of \(75 \mathrm{MPa}(10,900 \mathrm{psi}),(5)\) a matrix stress at composite failure of \(6.0 \mathrm{MPa}\) (870 psi), and (6) a matrix tensile strength of 60 MPa \((8700\) psi).
