| Abstract: |
The present study documents the development of capability related to the design, manufacture, analysis and experimental evaluation of continuous fibre additively manufactured composites. A candidate structure, a topology optimized truss, was selected to investigate the impact of defects introduced during the automated manufacturing process by experimentally evaluating the stiffness and load bearing capacity of the structure. AM composite and polymer trusses were experimentally evaluated, and the AM composite trusses were found to be four times as stiff and twice as strong as equivalent polymer trusses, despite the significant manufacturing induced defects present in the AM composite truss. The excellent result demonstrates the potential of continuous fibre reinforced composite AM components and highlight that further improvements in performance may be realized if the cause and effect of manufacturing defects can be understood and the impact of these defects minimized.
