Question
A continuous and aligned fiber-reinforced composite is to be produced consisting of 30 vol% aramid fibers and 70 vol% of a nylon matrix; and has a cross-sectional area of 320 mm? and is subjected to a longitudinal load of 44,500 N. Mechanical characteristics of these two materials are as follows: Aramid fiber 131 0.36 Nylon 24 0.39 Also, the stress on the polycarbonate matrix when the aramid fibers fail is 45 MPa. For this composite, compute (a) Major Passion’s ratio. (b) Minor Passion’s ratio. (c) The shear modulus.
