Preparation of iron oxide–coated aramid fibres for improving the mechanical performance and flame retardancy of multi jet fusion–printed polyamide 12 composites

open access: yesVirtual and Physical Prototyping, 2023
Multi jet fusion (MJF), a powder-based additive manufacturing technology, is suitable for fabricating fibre-reinforced polymer composites. However, the types of reinforcement fibres applied in MJF are limited due to the incompatibility between the fibres

The Influence of the Material Type and the Placement in the Print Chamber on the Roughness of MJF-Printed 3D Objects

open access: yesMachines, 2022
This paper describes a surface-roughness study performed on samples manufactured additively using the Multi Jet Fusion (MJF) technology. The samples were divided into three groups based on the material used in the process: polypropylene (PP ...

Production cost model of the multi-jet-fusion technology

open access: yesProceedings of the Institution of Mechanical Engineers, Part C: Journal of Mechanical Engineering Science, 2019
The paper presents a model of the production costs of the multi-jet-fusion technology that is based on a model of production costs of the selective laser sintering technology. The model is developed using the methodology of analysis of the event-driven process chain, which consists of modeling, batch assembly, setup, building, removal, and blasting ...

Next-to-leading order multi-leg processes for the Large Hadron Collider [PDF]

open access: yes, 2007
In this talk we discuss recent progress concerning precise predictions for the LHC. We give a status report of three applications of our method to deal with multi-leg one-loop amplitudes: The interference term of Higgs production by gluon- and weak boson

Numerical investigation of fiber orientations and homogeneity in powder bed fusion of fiber/polymer composites

open access: yesVirtual and Physical Prototyping, 2023
The packing characteristics of fiber/polymer powder in powder bed fusion additive manufacturing exhibit a high correlation with the mechanical behaviours of printed composite parts such as homogeneity and anisotropy.

Impact of minority concentration on fundamental (H)D ICRF heating performance in JET-ILW [PDF]

open access: yes, 2014
ITER will start its operation with non-activated hydrogen and helium plasmas at a reduced magnetic field of B-0 = 2.65 T. In hydrogen plasmas, the two ion cyclotron resonance frequency (ICRF) heating schemes available for central plasma heating ...

Overview of the JET results in support to ITER [PDF]

open access: yes, 2017
The 2014–2016 JET results are reviewed in the light of their significance for optimising the ITER research plan for the active and non-active operation. More than 60 h of plasma operation with ITER first wall materials successfully took place since its

Exploring the Jet Multiplicity in the 750 GeV Diphoton Excess [PDF]

open access: yes, 2016
The recent diphoton excess at the LHC has been explained tentatively by a Standard Model (SM) singlet scalar of 750 GeV in mass, in the association of heavy particles with SM gauge charges.
