A polymer composite material (10, 110, 210, 310) is described. The material includes a settable matrix material (12), a plurality of reinforcement members (14) and a plurality of capsule members (16). Each capsule member (16) includes a shell layer (22) encapsulating an indicator material (24). The polymer composite material comprises an initial condition in which each shell layer contains the indicator material, and a damaged condition in which at least one shell layer is ruptured, releasing indicator material. The polymer composite material is changed from the initial condition to the damaged condition by the application of a predetermined force to the polymer composite material.

L'invention porte sur un matériau composite polymère (10, 110, 210, 310). Le matériau comprend un matériau matriciel durcissable (12), une pluralité d'éléments de renforcement (14) et une pluralité d'éléments capsulaires (16). Chaque élément capsulaire (16) comporte une couche d'enveloppe (22) encapsulant un matériau indicateur (24). Le matériau composite polymère présente un état initial dans lequel chaque couche d'enveloppe contient le matériau indicateur et un état endommagé dans lequel une couche d'enveloppe est brisée, ce qui libère ainsi le matériau indicateur. Le matériau composite polymère passe de l'état initial à l'état endommagé suite à l'application d'une force prédéterminée au matériau composite polymère.
