Question
A continuous and aligned fiber-reinforced composite is to be produced consisting of 30 vol%
aramid fibers and 70 vol% of a polycarbonate matrix; mechanical characteristics of these two materials are as
follows:
Modulus of Elasticity
[GPa (psi)]
Tensile Strength [MPa
(psi)]
131 (19 × 10º)
3600 (520,000)
Aramid fiber
Polycarbonate
2.4 (3.5 × 105)
65 (9425)
Also, the stress on the polycarbonate matrix when the aramid fibers fail is 45 MPa (6500 psi).
For this composite, compute the following:
(a) the longitudinal tensile strength, and
(b) the longitudinal modulus of elasticity
