Abstract

We review in this paper recent experimental and theoretical developments which provide a rationale for the enhancement of indentation resistance of composites by recourse to gradients in elastic properties. We first examine brittle ceramics where the introduction of a controlled gradient in Young`s modulus, facilitated by the graded infiltration of a glassy phase that preserve transverse elastic isotropy, is shown to suppress Hertzian cone crack formation. We then consider anisotropic polymeric composites where it is demonstrated that, by choosing a functional dependence of the orientation of the fiber axes through the thickness of a laminated polymeric composite plate, the indentation strength can be improved substantially.
