    摘要: A self-indicating material system may include a solid polymer matrix having a first color, a first plurality of capsules in the matrix, and a plurality of particles in the matrix. The first plurality of capsules includes a first reactant, and the plurality of particles includes a second reactant, which forms a product when in contact with the first reactant. When a crack forms in the polymer matrix, at least a portion of the first plurality of capsules is ruptured, the first and second reactants form the product in the matrix, and the portion of the polymer matrix containing the product has a second color different from the first color. A self-indicating material system may include a solid polymer matrix, a plurality of capsules in the matrix, and an activator in the matrix, where the polymer matrix includes a first polymer and has a first color, the plurality of capsules includes a polymerizer, and the activator is an activator for the polymerizer. When a crack forms in the polymer matrix, at least a portion of the plurality of capsules is ruptured, the polymerizer and the activator form a second polymer in the crack, and the second polymer has a second color different from the first color.

    摘要: A composite material includes a polymer matrix, a polymerizer, and a plurality of capsules containing a corresponding activator for the polymerizer. The composite material can also include an adhesion promoter, and the polymerizer can be phase separated from the polymer matrix. The composite material can be made by dispersing the polymerizer and capsules into the polymer matrix. These composite materials can exhibit improved environmental stability, and can be used with a wider variety of activators.

    摘要: A composite material includes an elastomer matrix, a set of first capsules containing a polymerizer, and a set of second capsules containing a corresponding activator for the polymerizer. The polymerizer may be a polymerizer for an elastomer. The composite material may be prepared by combining a first set of capsules containing a polymerizer, a second set of capsules containing a corresponding activator for the polymerizer, and a matrix precursor, and then solidifying the matrix precursor to form an elastomeric matrix.
