"Laser ablation of polyethylene terephthalate non-woven fabrics";

Kurzfassung englisch:
Importance of product‐lifecycle‐management (PLM) increased in production engineering during the last years. Environmental as well as economic constraints account for intensified efforts in recycling and
substitution of non‐environmental friendly products. For example, Polyurethane (PU) foams should be replaced with non‐woven fabrics. Unfortunately, unlike foams, such non‐woven fabrics exhibit limited
possibilities in molding operations. Material removal by means of laser processing offers a possibility in a partial replacement of difficult moldings. Experiments of CO2‐laser processing of polyethylene terephthalate (PET) are presented. Laser parameters like beam shape, intensity distribution and process gases have been varied to optimise results.
