Investigation of ultrasonic consolidation for embedding active/passive fibres in aluminium matrices
thesis
posted on 2018-09-21, 09:09 authored by Choon-Yen KongThis is exploratory research, driven by industry requirements for a new and flexible
manufacturing process which incorporates and exploits high performance materials
for novel applications. The research was an investigation of the feasibility of the
production of metal adaptive composites by embedding active/passive fibres, using an
innovative Ultrasonic Consolidation (UC) technique. The UC process combines the
ultrasonic welding of metals with layered manufacturing techniques, to produce
freeform metal components using high-frequency, low-amplitude, mechanical
vibration.
In this study, two key mechanisms were identified which lead to embedding of fibres
within a metal matrix, known as the surface effect and volume effect. The surface
effect describes the interfacial friction between the two mating surfaces, while the
volume effect concerns the internal stresses and plastic deformation within the metal,
during ultrasonic oscillation. [Continues.]
