Bewertung des Preformprozesses mit Hilfe der optischen Verformungsmessung

Abstract

The preforming of carbon fiber semi-finished parts is responsible for a major share of the total costs at RTM processes. In order to identify the areas with the highest degree of deformation, an optical forming analysis was used. One requirement for this measurement technique is the application of a regular grid of red dots. Therefore different methods for the application have been investigated and automated. Furthermore the integration of the optical camera into the process has been achieved. As a result the measuring process could be automated. In a final step the measuring technology was validated at the automated preforming process of an aircraft fuselage frame segment.
