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)
Tensile Strength (MPa)
silicon Carbide
400
3600
Polycarbonate
2.4
65
Also, the stress on the polycarbonate matrix when the silicon
Carbide fail is 45 MPa. For this composite, compute
a) The longitudinal tensile strength
b) The longitudinal modulus of elasticity
