“…Although studies have been performed on the probabilistic characterization of the random transport properties of fibrous media [2][3][4], the random effects are usually neglected in the available optimization or on-line control schemes [5][6][7] which employ common simulation softwares for mold filling. Available stochastic studies in the RTM context [8][9][10][11][12] mostly depend on the Monte Carlo simulation (MCS), which is computationally expensive for a fast uncertainty analysis or to be combined with other algorithms for optimization or sensitivity analysis.…”

“…Analytical prediction of the through-thickness permeability requires geometrical characterization of flow channels formed in the respective fabric structure. While X-ray micro-Computed Tomography (-CT) can be used for scanning the internal architecture of 3D materials [12][13][14][15] , as illustrated in Figure 1c and d, data used for permeability prediction were obtained using optical microscopy.…”

Through-thickness permeability study of orthogonal and angle-interlock woven fabrics

Abstract:Three-dimensional (3D) woven textiles, including orthogonal and angle-interlock woven fabrics, exhibit high inter-laminar strength in addition to good in-plane mechanical properties and are particularly suitable for lightweight structural applications. Resin Transfer Moulding (RTM) is a cost-effective manufacturing process for composites with 3D woven reinforcement. With increasing preform thickness, the influence of through-thickness permeability on RTM processing of composites becomes increasingly significant. This study proposes an analytical model for prediction of the through-thickness permeability, based on Poiseuille's law for hydraulic ducts approximating realistic flow channel geometries in woven fabrics. The model is applied to four 3D-woven fabrics and three 2D woven fabrics. The geometrical parameters of the fabrics were characterized employing optical microscopy. For validation, the through-thickness permeability was determined experimentally. The equivalent permeability of inter-yarn gaps was found to account for approximately 90 % of the through-thickness permeability for the analysed fabrics. The analytical predictions agree well with the experimental data of the seven fabrics.

“…As the technology becomes more readily available, with increased computing power and storage space at lower costs, it is envisioned that more and more cost-effective and feasible industrial CT applications will emerge. In the academic research environment, industrial CT scanning has been applied in many diverse fields, including geology [4,5], archaeology [6], forensic science [7], forestry and wood science [2,8], biology [1,9], soil science [10], composite science [11], and mechanical and electronic engineering [12,13].…”

Microfocus X-ray computed tomography (CT) scanning is a three-dimensional (3D) nondestructive technique that is useful in many research and technology fields. Similar to twodimensional (2D) X-ray inspections, this 3D technology allows the investigation of almost any material down to 1 micron spatial resolution and higher. In this paper we present a characterisation and demonstration of the use of CT to analyse the 3D volume of laser sintered parts including analyses of porosity, dimensional measurement of cracks and other features, and a demonstration of quality testing methods which can be used to quickly identify problems in production. OPSOMMINGMikrofokus X-straal rekenaar-tomografie (RT) is 'n drie-dimensionele (3D) nie-destruktiewe tegniek wat bruikbaar is in baie navorsing en tegnologie velde. Soortgelyk aan twee dimensionele (2D) X-straal inspeksies, laat hierdie 3D tegnologie dit toe om enige materiaal in 3D te ondersoek tot 1 mikron (en hoër) ruimtelike resolusie. In hierdie artikel word 'n karakterisering en demonstrasie van die gebruik van RT aangebied om die 3D volume van laser-gesinterde onderdele te analiseer, insluitend die analise van porositeit, dimensionele metings van krake en ander eienskappe en 'n demonstrasie van kwaliteit toets metodes wat gebruik kan word om vinnig probleme in produksie te identifiseer.
