Abstract
A self-healing fabric for an inflatable of an evacuation system may comprise a fabric layer, an interior thermoplastic polymeric layer formed over a first side of the fabric layer, and an exterior thermoplastic polymeric layer formed over a second side of the fabric layer. The interior thermoplastic polymeric layer may include a first healing agent. The exterior thermoplastic polymeric layer may include a second healing agent.
Claims20
A self-healing fabric for an inflatable of an evacuation system, comprising:
- a fabric layer;
- an interior thermoplastic polymeric layer formed over a first side of the fabric layer, the interior thermoplastic polymeric layer including a first healing agent;
- and
- an exterior thermoplastic polymeric layer formed over a second side of the fabric layer, the second side being opposite the first side, the exterior thermoplastic polymeric layer including a second healing agent,
- wherein the interior thermoplastic polymeric layer and the exterior thermoplastic polymeric layer each includes a thermoplastic polymeric material with catalysts and encapsulated healing agents of the first healing agent and the second healing agent, respectively, which are dispersed therein, wherein the thermoplastic polymeric material includes polyols, wherein the polyols include at least one of polyether, polyester, or polycaprolactone, wherein the catalysts include a tin-based catalyst, and wherein the encapsulated healing agents includes at least one of isocyanate or an aliphatic group.
An inflatable for an evacuation system, the inflatable comprising:
- a self-healing fabric defining an inflation chamber, wherein the self-healing fabric comprises:
- a fabric layer;
- an interior thermoplastic polymeric layer formed over the fabric layer and oriented toward the inflation chamber, the interior thermoplastic polymeric layer including a first healing agent;
- and
- an exterior thermoplastic polymeric layer formed over the fabric layer and oriented away from the inflation chamber, the exterior thermoplastic polymeric layer including a second healing agent.
A method of forming an inflatable for an evacuation system, the method comprising:
- forming a self-healing fabric by:
- forming a first thermoplastic polymeric layer including a first healing agent over a first side of a fabric layer;
- and
- forming a second thermoplastic polymeric layer including a second healing agent over a second side of the fabric layer;
- and
- forming an inflatable chamber of the inflatable using the self-healing fabric.
