Effect of chisel edge in ultrasonic assisted drilling of carbon fibre reinforced plastics (CFRP)
Ultrasonic assisted drilling (UAD) has been reported effective for thrust force reduction during drilling of CFRP resulting in lower exit delamination. However, this process is not fully understood in relation to machining theory. This work focused on understanding the separate effects of chisel and cutting edges during UAD in comparison with conventional drilling (CD). Experiments were perform...
متن کاملJoining of Carbon Fibre Reinforced Plastics for Automotive Applications
The introduction of carbon-fibre reinforced plastics in load bearing automotive structures provides a great potential to reduce vehicle weight and fuel consumption. To enable the manufacture and assembly of composite structural parts, reliable and cost-effective joining technologies must be developed. This thesis addresses several aspects of joining and load introduction in carbon-fibre reinfor...
متن کاملSome observations in grinding unidirectional carbon fibre-reinforced plastics
This paper investigates the grinding performance of epoxy matrix composites reinforced by unidirectional carbon fibres, using an alumina grinding wheel. Emphasis was placed on understanding the effect of fibre orientations and grinding depths on the grinding force and surface integrity, and on understanding the grinding mechanisms, with a comparison to orthogonal cutting. It was found that grea...
متن کاملDrilling of carbon fibre reinforced laminates – a study
The distinguishing characteristics of carbon fibre reinforced laminates, like low weight, high strength or stiffness, had resulted in an increase of their use during the last decades. Although parts are normally produced to “near-net” shape, machining operations like drilling are still needed. In result of composites non-homogeneity, this operation can lead to delamination, considered the most ...
متن کاملDrilling of Fiber-Reinforced Plastics - Tool Modeling and Defect Prediction
Fiber reinforced polymer (FRP) composites have been steadily replacing metals as choice engineering materials for various applications. Although FRPs can be manufactured to near-net shape, post processing operations such as machining are required to create some features (such as holes). In order to drill holes efficiently with the least waste and defects, it is essential to understand the machi...
