Title: Metoda in naprava za selektivno jedkanje kompozitnih materialov z lasersko ablacijo [SL], Method and Device for Selective Etching of Composite Materials with Laser Ablation [EN]
Description: The subject of invention is a method for surface treatment of composite materials having a polymer matrix and a device with which selective etching of a composite surface is carried out. The method is based on surface treatment of a composite with a jet of energetic particles, first of all a bundle of laser rays, i.e. with laser ablation. Polymer is selectively partly or completely removed from the surface and fillers are left almost intact. Such changes of surface lead to the essential change of surface properties, first of all adhesion and porosity of various coatings on a composite.
