b) A continuous and aligned carbon fiber-reinforced composites consists of 40 vol% of carbon fiber having modulus of elasticity of 69 GPa and 60 vol% of a polyester resin that when hardened displays a modulus of 3.4 GPa. (i) Compute the modulus of elasticity of the composite in the longitudinal direction. (ii) If the cross-sectional area is 250 mm? and a stress of 50 MPa is applied in this longitudinal direction, compute the magnitude of the load carried by each of the fiber and matrix phases. (iii) Determine the strain that is sustained by each phase when the stress in part (ii) is applied.

b) A continuous and aligned carbon fiber-reinforced composites consists of 40 vol% of
carbon fiber having modulus of elasticity of 69 GPa and 60 vol% of a polyester resin
that when hardened displays a modulus of 3.4 GPa.
(i)
Compute the modulus of elasticity of the composite in the longitudinal
direction.
(ii)
If the cross-sectional area is 250 mm? and a stress of 50 MPa is applied in this
longitudinal direction, compute the magnitude of the load carried by each of
the fiber and matrix phases.
(iii)
Determine the strain that is sustained by each phase when the stress in part (ii)
is applied.
