A composite has a cross-sectional area of 320 mm2 and is subjected to a longitudinal load of 44,500 N.
The continuous and aligned fiber-reinforced composite is to be produced consisting of 30 vol% aramid fibers and 70 vol% polycarbonate matrix; the mechanical characteristics of these two materials are as follows:
Aramid fiber: Modulus of elasticity, 131 GPa; Tensile strength 3600 MPa;
Polycarbonate: Modulus of elasticity, 2.4 GPa; Tensile strength 65 MPa;
Compute the magnitude of the stress on each of the fiber and matrix phases.
1- What strain is experienced by the composite?
2-Calculate the fiber-matrix load ratio?
3- Compute the magnitude of the stress on each of the fiber and matrix phases?
4-Calculate the actual loads carried by both fiber and matrix phases?
