“…These systems make it easier to perform multiple longer timescale studies, albeit using much longer scan times compared to synchrotron CT. Since laboratory X-ray CT systems capable of micro resolution have only recently emerged, only a few studies to date [12,[22][23][24][25] have used laboratory systems to study material damage at the micro-structural level. The studies have tended not to consider individual fibre fractures because of insufficient resolution (e.g.…”

“…Some studies have used staining techniques to increase the visibility of the damage thereby lessening the resolution requirements. In a recent study by Yu et al [23], the fatigue damage progression of matrix cracks and delaminations in a larger test specimen (16x2mm in cross-section) was studied for a 3D woven carbon fibre composite at 10.7 micron voxel size by staining with contrast agent.…”

“…[3][4][5]. X-ray CT image-based numerical models (most commonly the finite element (FE) method) have also been recently built to investigate the mechanical behaviour of some multi-phase materials, such as homogenisation of elastic properties of fibre reinforced concrete [6], damage evolution of carbon-carbon composites [7], and complicated nonlinear fracture in concrete [8,9].…”

This paper develops a new fibre tracking algorithm to efficiently locate fibre centrelines (skeletons), from X-ray Computed Tomography (X-ray CT) images of carbon fibre reinforced polymer (CFRP), which are then used to generate micro-scale finite element models. Threedimensional images with 330nm voxel resolution of multidirectional [+45/90/-45/0] CFRP specimens were obtained by fast synchrotron X-ray CT scanning. Conventional image processing techniques, such as a combination of filters, delineation of plies, binarisation of images, and fibre identification by local maxima and ultimate eroding points, were tried first but found insufficient to produce continuous fibre centrelines for segmentation, especially in regions with highly congested fibres. The new algorithm uses a global overlapping stack filtering step followed by a local fibre tracking step. Both steps are based on the Bayesian inference theory.The new algorithm is found capable of efficiently define fibre centrelines for the generation of micro-scale finite element models with high fidelity.

“…Damage tolerance design is the most promising technique for advanced composite structures since a structure could be designed to operate in the presence of damage [1][2]. Due to the high uncertainty in predicting damage initiation, it is necessary to continuously monitor the structure's health state [3][4][5][6]. In addition to this, fibre/polymer composites suffer from performance degradation because of the environmental loading conditions.…”

In this work, a numerical model is presented to describe the thermal response of a graphene/polymer nanocomposite. The approach is based on the multi-scale method and consists of a unit cell and a Representative Volume Element (RVE) built on a finite element interface. At the unit cell level, the material's nano-characteristics (filler geometry, phase thermal properties, interfacial properties) are employed to calculate the local thermal conductivity. The material's architecture is modelled at the RVE level by incorporating the previously obtained local thermal properties. A statistical sample was studied and the average thermal response was compared to experimental data.
