Disclosed herein is an intrinsically self-healing composite based upon in situ thermal remendability of an embedded polymeric interphase. The fiber-reinforced composite (FRC) material may incorporate a thermoset polymer with a defined glass transition temperature (T.sub.g) and/or a thermoplastic material of amorphous or semi-crystalline nature. The polymeric interphase can be incorporated as a plurality of particles, fibers, meshes, films, or 3D-printed structures. The self-healing composite includes a resistive heating component as a structural element that minimizes electrical energy demand and impact on mechanical integrity. Healing occurs in situ via resistive heating and can be enabled below, at, or above the glass-transition temperature of the FRC matrix, demonstrating viability for in-service repair under sustained loads. In addition to providing rapid healing functionality, the polymeric interphase increases inherent resistance to interlaminar fracture. Repeated heal cycles have been achieved in a double cantilever beam (DCB) fracture test without significant degradation in performance.

A fabric and elastomeric material (referred to as a fabric trilayer) combined with a sealant may be applied in such a fashion so as to eliminate or minimize air entrapment in an elastomeric composite structure that forms a seal-sealing volume. The performance of the self-sealing volume is dramatically improved with this minimizing of air entrapment. Surprisingly and unexpectedly, this construction approach may be accomplished without significantly adding to the weight or thickness of the volume and without affecting the outer dimension of the self-sealing volume. Thus, a method and system for forming a self-sealing volume are described. The system includes an elastomeric composite structure comprising at least one layer of an elastomeric material derived from a neat (no solvent) elastomeric material that does not substantially react at room temperature.
