3.
The geometry of the reinforcing phase in a composite greatly determines the
overall properties. Polycarbonate has a Modulus of Elasticity=2.2 GPa, Tensile
Strength-62.5 MPa. Carbon Fiber has a Modulus of Elasticity=228 GPa, Tensile
Strength=3.5 GPa. For a 40 vol% carbon fiber and a 60 vol% polycarbonate matrix
composite, compute the Tensile Strength and Young's Modulus for the composite for the
following situations. Assume longitudinal loading.
a. Continuous and aligned fibers
b. Discontinuous and aligned fibers with I> le where 1 = 101, (K = 1).
c. Discontinuous and aligned fibers with I< le where I= 0.51, (K = 1).
d. Which of these composites is the strongest? Which is the stiffest (has the highest
Young's Modulus)?
