For
the isostrain configuration:
ECp= VfEf + (1 - Vf)Em; Vf + Vm = 1 · For the isostress configuration: ECn = 1/{(Vf /Ef) + (1 - Vf)/Em} · The practical limit on the fiber volume fraction, Vf , is about 0.8 and corresponds to the close packing of cylinders. · The composite modulus for these two conditions is shown as a function of the fiber volume fraction. Spherical particles have a reinforcing effect similar to the isostress fiber orientation. |
