Abstract Using carbon-fibre-reinforced polymer (CFRP) composites for electromagnetic interference (EMI) shielding has become a rapidly emerging field. This state-of-the-art review summarises all the recent research advancements in field of properties CFRP composites, with exclusive attention paid to experimental work. It focuses on (1) important mechanisms and physical phenomena process anisotr...

A shear-lag model with a cohesive fibre–matrix interface has been developed for the analysis of stress transfer between the fibre and the matrix in fibre-reinforced composites in this paper. A bilinear cohesive damage evolution law is used to describe the fibre–matrix interface behaviour. The governing equations for the interfacial shear stress and the axial stress in the fibre are derived. Acc...

In the frame of Horizon 2020 European C3HARME research project, manufacture ZrB2-based CMCs was developed through different processes: slurry infiltration and sintering, radio frequency chemical vapour (RF-CVI) reactive metal (RMI). To assess high temperature stability, room bending strength measured after oxidizing samples at 2278 K compared to as-produced materials. Microstructures were analy...

Abstract In the current research, waste from woollen yarn production was analysed. Woollen as raw material used for of soft thermal insulation mats. Two types mats were produced in a textile plant: thermally untreated and treated. Properties such fibre composition, structure, conductivity treated studied. During composition analysis waste, quantity long, medium length, short fibres determined. ...

This paper reports on the production and evaluation of a new class “Z-axis” composite sandwich panel where core consists dense array vertically-aligned, 3 mm long E-glass fibre “beams”. The bundles were aligned using electrostatic charging. A procedure was developed to retain orientation short-fibre whilst they impregnated cured with an epoxy/amine resin system. skins manufactured from 4-ply ca...

RTM technology is an attractive alternative for high strength steels by composites with a high fibre volume content. The main advantage is a reduction of the assembly costs, since components can be made in one piece rather than out of a compilation of components. Above that the lower specific weight of a composite product results in a weight reduction. In order to obtain more fundamental knowle...

Scatter dark field imaging with an X-ray grating interferometer has been implemented to probe the micro-structure of polymers, fibre-reinforced composites or light metals. The method has now been developed further to enable the characterisation of the fibre laminate structure. Experimental results obtained by scatter dark field computed tomography illustrate how information on the microstructur...

In this paper we determine, in dimension three, the effective conductivities of non periodic high-contrast two-phase cylindrical composites, placed in a constant magnetic field, without any assumption on the geometry of their cross sections. Our method, in the spirit of the H-convergence of Murat-Tartar, is based on a compactness result and the cylindrical nature of the microstructure. The homo...
