Abstract [en]

For damage indication needs in polymer composites, three smart acrylic coatings based on microencapsulated crystal violet lactone leuco dye with embedded developer silica gel and methyl 4-hydroxybenzoate were elaborated. Damage visualization ability upon duralumin substrates was tested. Indentation tests were conducted in the interval of 0.0005-0.55 J of mechanical work. Digital image analysis was used for evaluation of the visual response in the form of "bruise" spots. The measure of response intensity was relative excess of blue color above achromatic gray in the scanned images of the "bruise" spots. This technique allowed detecting influence of the coating formulations onto the substrate damage visualization. © The Author(s) 2012.
