Composite Materials

· The diagram illustrates an element, dx, of the fiber at the location x being loaded by the interfacial shear stress, τ. The fiber stress at this location is σ_f(x).
· For an assumed constant interfacial shear stress, τ, the tensile stress in the fiber is given by:

· The stress distribution on this simple model increases linearly with distance from the free ends of the fiber and reaches a constant maximum value over the central isostrain region of the fiber.
