The Newcastle University research output collection, currently available on ePrints, will shortly be moving to a new open repository platform, Figshare. To prepare for the data migration we have paused adding new content to ePrints, and will resume once the new repository is launched. During this time you will continue to have access to ePrints (but no new content will appear). We will share updates here when available.

Abstract

© 2024 Elsevier B.V.. All rights reserved.This paper presents a quantitative assessment of particles released when machining nanostructured composite materials. Two different nanocomposite materials (graphene/epoxy and halloysite nanoclay/polyester) were micro machined using carbide end mills under various cutting conditions. A portable particulate monitor (Turnkey Dustmate, laser light scattering monitor) was used at different locations at a distance from the machining zone (starting from 10 cm to 1 m) to measure the released PM10, PM2.5, PM1concentrations (diameter <10, <2.5 and <1 μm, respectively, with a lower limit of 0.5 μm). DustMate results showed that concentrations across the three size categories were well below workplace exposure limits.
