    • 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.
    • 自指示材料系统可以包括具有第一颜色的固体聚合物基质,基质中的第一多个胶囊和基质中的多个颗粒。 第一多个胶囊包括第一反应物,并且多个颗粒包括第二反应物,其在与第一反应物接触时形成产物。 当在聚合物基体中形成裂纹时,第一多个胶囊的至少一部分破裂,第一和第二反应物在基质中形成产物,并且含有产物的聚合物基质的部分具有不同于 第一种颜色。 自指示材料系统可以包括固体聚合物基质,基质中的多个胶囊和基质中的活化剂,其中聚合物基质包括第一聚合物并且具有第一颜色,所述多个胶囊包括聚合反应器, 并且活化剂是聚合反应器的活化剂。 当在聚合物基质中形成裂纹时,多个胶囊的至少一部分破裂,聚合器和活化剂在裂纹中形成第二聚合物,并且第二聚合物具有与第一颜色不同的第二颜色。
