Consider a continuous and aligned fiber reinforced

3. Consider a continuous and aligned fiber reinforced composite with the following properties:
elastic modulus of fiber = 270 GPa, elastic modules of matrix = 6 GPa, volume fraction of
fiber 33%. If this composite is loaded in a direction parallel to the fibers and the stress
sustained by the matrix is 0.003 GPa, calculate the stress sustained by the fibers under the
same load. Assuming that the composite shows elastic behavior under the stress. Select the
closest answer.
A. 0.135 GPa
B. 1.135 GPa
C. 2.135 GPa
D. 3.135 GPa
4. Which of the following descriptions for the tensile stress-strain behavior of a continuous and
aligned fiber composite under longitudinal loading is WRONG?
