A continuous and aligned fibrous reinforced composite having a
cross-sectional area of 875
mm2 is subjected to an external tensile load. If the
stresses sustained by the fiber and matrix
phases are 255 MPa and 8.35 MPa, respectively, the force sustained
by the fiber phase is 85,800
N, and the total longitudinal composite strain is 1.65 x
10-3, determine the following:
(20 Points)
(a) Volume fraction of fiber and matrix
(b) The force sustained by the matrix phase
(c) The modulus of elasticity of the composite material in the
longitudinal direction
(d) The moduli of elasticity for fiber and matrix phases
