A continuous and aligned carbon fiber-reinforced composite consists of 60% by volume of high-strength carbon
fibers having a tensile strength of 3.9 GPa reinforced in a polyester resin that, when hardened, displays a tensile
strength of 50 MPa. What is the tensile strength of this composite in the longitudinal direction?

Answer #1

Solution:

  • Volume fraction of high carbon steel, V1 = 0.60
  • Volume fraction of the reinforced polymer resin, V2 = 0.30
  • Tensile strength of high carbon steel, = 3.9 GPa
  • Tensile strength of reinforced polymer resin, = 50 MPa = 0.050 GPa (1MPa = 1000 GPa)

Therefore, he tensile strength of this composite in the longitudinal direction is given by
