“…The reason for the changes in the erosion rate of the composite material is the conversion of material to that of a semi-ductile nature. Similar results were observed by the researchers [ 29 , 30 ].…”

Solid particle erosion inevitably occurs if a gas–solid or liquid–solid mixture is in contact with a surface, e.g., in pneumatic conveyors. Nowadays, an erosive failure of the component after the usage of a long period has been gaining the interest of the researchers. In this research work, carbon fibre-reinforced polymer (CFRP) composites are prepared by varying the tow sizes of fibres, such as 5k, 10k, and 15k. The prepared composites are subjected to erosion studies by varying the process parameters, such as the impact angle (30, 60, and 90 degrees) and velocity (72, 100, and 129 m/s). The Taguchi orthogonal array design has been employed for the experimental plan and the erosion rate and surface roughness are observed for each run. The changes in the responses are reported for varying process parameters. The higher erodent velocity of 129m/s leads to higher erosion rates and forms poor surface quality. The minimum impact angle of 30 degrees provides higher erosion rates and higher surface roughness than the other impingement angles. Finally, the eroded surface of each sample is examined through microscopic and 3D profilometer images and the erosion mechanism is analysed at different conditions. The eroded particles supplied at lower speeds do not penetrate the composite surface. However, it is well-known that the lower the collision force, the harder the traces on the surface, yet no sign of fibre breaking or pull-out is observed. The passage of erodent particles on the composite caused surface waviness (flow trace), which prevents the surface from degrading.

“…The use of a 3 rd party heating core is required so that hardened steel and ruby tipped nozzles can be used. One such system is the Solex3D high temperature core for the Ultimaker 3 [128]. Figure 37 shows an image of the Solex3D core which replaces the Ultimaker 3's core to allow abrasive filaments to be processed at higher temperatures.…”

The design of components for the optical industry requires a consideration into the thermal expansion co-efficient of the materials used. Often the body material of an optical system exceeds the thermal expansion of the lens material. This can lead to lens decentre and misalignment. This thesis will investigate the use of additive manufacturing to tailor the thermal expansion co-efficient of the parts produced so that they match the thermal expansion co-efficient of the lens material. Several state-of-the-art additive manufacturing methods are investigated to achieve this. These include metal laser powder bed fusion, polymer fused deposition modelling, and continuous fibre re-enforced polymer fused deposition modelling. A method used to tailor the co-efficient of thermal expansion focuses on the design of the components, while another method focuses on the adjustment of the materials used. The design of an optical system features two metals with different thermal expansion co-efficients which work together to produce a different overall thermal expansion co-efficient similar to the lens material. Another method investigates the use of the low expansion invar alloy, and the controlled expansion aluminium - silicon alloy. Adjusting the elemental constituents by mixing the alloy powders with elemental powders has shown to successfully change the overall constituents of the printed alloy, opening up the avenue for tailoring thermal expansion in-situ with the build process. A promising method of controlling thermal expansion with polymers is shown by introducing inclusions into the polymer filament feedstock material. The introduction of carbon and glass fibres as well as metal and organic particles shows a remarkable ability to adjust the co-efficient of thermal expansion over a wide range. Using a fibre polymer printer, a composite can be printed with a layer of carbon, glass, or Kevlar fibre laid in a predetermined orientation. This method provides the widest range of thermal expansion control.
