Abstract

Die Erfindung betrifft ein Verfahren zur berührungslosen groß­ flächigen Entlackung von Lackschichten, insbesondere an Faser­ verbundwerkstoffen, wobei optische Energie vorzugsweise von einem gepulsten Laser die zu entlackende Oberfläche so schnell erhitzt, daß die bestrahlte Fläche schneller abdampft als ab­ sorbierte Energie in tiefere Schichten diffundiert und die damit verbundenen Lichtemissionen des abströmenden Plasmas zur Regulierung der Entlackungstiefe insbesondere bei Mehr­ schichtsystemen ausgenutzt werden. The invention relates to a method for contactless large surface stripping of paint layers, especially on fiber composite materials, optical energy preferably from a pulsed laser so quickly the surface to be stripped heated that the irradiated area evaporates faster than from sorbed energy diffuses into deeper layers and the associated light emissions of the outflowing plasma to regulate the paint stripping depth, especially with more layer systems can be exploited.
