Problem 4
Calculate the tensile modulus of elasticity of a unidirectional carbon-fiber-reinforced-plastic composite
material that contains 64 percent by volume of carbon fibers and is stressed under isostrain conditions.
The carbon fibers have a tensile modulus of elasticity of 54.0 × 10° psi and the epoxy matrix a tensile
modulus of elasticity of 0.530 x 10° psi.
The compressive strength of aramid fiber is about one-eighth of its tensile stress. Estimate the smallest diameter of a rod on which the aramid fiber can be wound without causing kinks, etc. on its compression side.
