Selective Tape-Laying for Cost-Effective Manufacturing of Optimised Multi-Material Components

Wing Profile

AFPT has proposed a wing profile as a demonstrator case study. This part is selected specifically in order to demonstrate the processing developments of multiple robots co-operating to layup on complex curved surfaces.

For this purpose it is necessary to begin with a relatively large workspace in order to give some scenarios in which the robots can work without collisions. The wing profile shown is approximately 500 mm × 2000 mm.

AFPT designed two demonstrator moulds that cover the two main challenging curvature features of the component. These moulds offer the opportunity to prove the capabilities of AFPT’s tape placement equipment in applying local reinforcements on 3D curved surfaces. AFPT will test its latest developments by applying short local reinforcement under different angles.

Load cases and evaluation items:

  • Accurate tape location with full (and consistent) consolidation over the entire tape length
  • Automated attachment & bonding of the first layer directly to component
  • Avoid post-treatment
  • Increase tape-laying speed

The trials shall also aim to make a statement about the benefits of increased process efficiency and total cost impact of using multiple robots, and also the efficiency of using integrated planning tools such as those developed by CGTech.
