<p>Composition comprises a matrix, probes (5-40 wt.%) (14) comprising at least one compound whose physico-chemical properties are modified by applying an external pressure, where the probes are directly contacted with the matrix. Independent claims are included for: (1) a film for coating a surface comprising an external layer formed the coating composition, and an adhesive layer; (2) a process for coating a piece comprising applying a composition layer on a surface of the piece and subjecting the layer to strengthening treatment, where the layer has a thickness of 1-200 mu m; (3) a structural piece made of a composite material comprising a surface coated layer obtained from the composition; and (4) a process for evaluating a shock received by a structural piece comprising calibrating the surface coating of the piece by impact tests or by producing the pressure on the coated specimens, determining a threshold impact energy inducing a threshold modification of the physico-chemical probes, and estimating the modification of physico-chemical properties of the probes in the location of shock according to the threshold, where the estimation is effected by an optical analysis unit.</p> |
