This
presentation deals with the fabrication, modeling, and identification
(testing) of self-healing polymer and polymer-matrix composites.
Healing (and self-healing) occurs in a variety of materials including
rock salt, sinterized metals, ceramics, polymer-matrix composites,
bone, and so on. Fabrication/processing aspects of a self-healing
system suitable for polymers and polymer-matrix composites will
be described. Also, an overview of Continuum Damage-Healing Mechanics
(CDHM) will be presented followed by a description of its associated
parameter identification. CDHM is an extension of Continuous
Damage Mechanics (CDM) recently developed by the author to model
healing processes. While the theoretical framework of CDHM is
general, parameter identification depends on the particular material
being modeled and the specific material tests that are feasible
to conduct for that class of materials. Preliminary results are
shown in order to illustrate the healing behavior of damaged
polymeric matrix composites. Healed and not healed cases are
discussed in order to show the model capability and to describe
possible evolution of the healed system.
