Hodnocení vlivu obráběcích a dělicích technologií na kvalitu hran a delaminaci vláknových kompozitů v automobilových aplikacích

Abstract

This thesis examines the experimental evaluation of the influence of cutting technologies on the quality of cut edges and the occurrence of delamination in fiber-reinforced polymer matrix composites. The quality of the cut is examined and evaluated on the cut surfaces of two types of composite steering wheel panels. Two cutting technologies were used and compared for the steering wheel blanking: CNC milling and abrasive waterjet (AWJ) cutting. The main objective of this work is to comprehensively evaluate and compare how individual cutting methods affect the quality of the cut edge, the extent and nature of delamination, damage to the fiber reinforcement, and surface roughness. AWJ performed best in the evaluation, particularly for hybrid laminates. For carbon laminates, both technologies were applicable, but AWJ was generally gentler. In the overall assessment, however, it is necessary to consider the trade-off between cut quality and economic demands, as hybrid laminates may offer specific functional advantages but at the cost of significantly higher production costs.
