Via the concept of local defect resonance it is possible to efficiently and selectively activate defects in composite materials, e.g. delaminations. Thermography and shearography are used for fast defect detection with vibration excitation.

The application of digital image correlation at the micro-scale to nano-engineered fiber-reinforced composites is investigated. The resulting strain maps are compared with a finite element model, simulating CNTs grown radially on microfibers.

Failure and oxidation of self healing phases in CMC are studied in-situ using μCT. Crack networks were analysed during tension at high temperature (20°C to 1250°C). Image based FE models were built to better understand tests.

A novel in situ CT device is used to perform compression tests on closed-cell polymeric foams to analyse the deformation behaviour. With the introduction of a phase field function, complex structures can be meshed for simulation.

In this study, fatigue damage progression in terms of individual fibre fractures and off-axis cracks in a NCF fibre composite is observed in-destructively by transilluminated white light imaging and ex-situ X-ray computed tomography.

The paper describes a new approach for analysing damage and failure phenomena in combined hybrid joints. A combination of destructive and non-destructive test methods makes it feasible to detect crack initiation and propagation in single-lap joints.

The aim of this study is to understand the void formation, transport mechanisms and porosity evolution during OoA consolidation process in laminates produced by hand lay-up (HLU) and cured in an industrial oven, using vacuum bag only (VBO) technique.

This paper is regarding volume porosity evaluation in CFRP using XCT by implanting known amount of voids. Drilling of holes of 200 and 300 µm is performed. Scans at various voxel sizes are analysed. Repeatability is checked and verified.

We present results of a novel Talbot-Lau grating interferometry desktop µ-XCT-system which are compared to conventional high resolution XCT-results. Three different kind of damages in composites are characterized: impact, tensile and cyclic loading.

In this paper, the compressive failure of unidirectional carbon fibre/epoxy composite rods is studied using ultra-fast time-lapse synchrotron X-ray imaging, involving both two-dimensional radiography and three-dimensional computed tomography.
