Experimental determination of processing parameters for in-situ tape placement

Abstract

Two different heat sources - a xenon flashlamp and laser - for in-situ AFP of CF/LM-PAEK tape have been evaluated. The proof of concept for flashlamp heating was reached. However, consolidation of laminates was achieved at significantly lower placement speeds as compared to the laser source which lowers productivity. Mechanical properties and the degree of crystallization was thoroughly investigated. In terms of industrial application, the flashlamp system could not yet show comparable readiness to the laser system which was thus chosen for the production of the upper shell of the Multifunctional Fuselage Demonstrator.
