Design and evaluation of additively manufactured parts with three dimensional continuous fibre reinforcement

摘要: Additive manufacturing (AM) provides many benefits such as reduced lead times, streamlined supply chains, part consolidation, structural optimisation and improved buy-to-fly ratios. Barriers to adoption include high material processing costs, low build rates, isotropic properties, variable conditions. Currently AM polymer parts are far less expensive manufacture than metal parts, therefore improving the properties of is highly desirable. This paper introduces a design methodology used integrate continuous reinforcement into with aim their mechanical properties. The method validated testing three case studies, pulley housing, hook universal joint demonstrate applicability for tensile, bending torsion loading types respectively. Physical showed that it was possible improve strength by over 4000%, elongation failure 2000% stiffness approximately 200%. In addition integrating condition monitoring capabilities demonstrated. An analysis specific suggests reinforced comparable aluminium alloys, suggesting in some cases composite could supplant more costly parts.
