Development of Removable Visual Impact Indicator or Polymer Composite Materials

Blog Article

The prototype of removable 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 knowall.blog of an impact on the composite surface.

Ball-drop tests demonstrated the increase of the magnitude of the visual response with the impact energy at deva curl arc angel 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.
