Development of Removable Visual Impact Indicator or Polymer Composite Materials

The prototype of removable T shirts visual impact indicator for thermoset polymer composite materials is developed, and its characteristics are experimentally determined.The indicator is a fabric tape glued by epoxy to the surface of the polymer composite.The tape is impregnated with a composition that provides a visual response at the place of an impact on the composite Hair Colour Retouch surface.Ball-drop tests demonstrated the increase of the magnitude of the visual response with the impact energy at different substrate hardnesses.The shelf-life and mode of the tape storage until commissioning are determined.

Peel tests showed the ability to remove a used indicator without damaging the surface of the composite.
