Detection and Localization of Delaminations in Thin Carbon Fiber Reinforced Composites with the Ultrasonic Polar Scan Vrije Universiteit Brussel
In this paper, the hybrid compliance-stiffness matrix method for simulating wave propagation in (delaminated) multilayered media with viscoelastic anisotropy has been confronted with high-quality amplitude and phase experiments on delaminated composites, obtained using the ultrasonic polar scan setup (UPS) in transmission by considering harmonic as well as pulsed ultrasound. Results are presented for multiple thin carbon/epoxy laminates with an ...
Digital volume correlation for meso/micro in-situ damage analysis in carbon fiber reinforced composites KU Leuven
Recently, in-situ X-ray Computed Tomography (CT) has shown its potential for 3D damage analysis in composite materials. However, the characterization of damage in X-ray tomograms is not always straightforward, and it requires post-processing of the 3D images. In this study, we explore the potential of Digital Volume Correlation (DVC) for the detection and characterization of damage in fiber-reinforced composites, where fibers provide the ...
Surface and sub-surface degradation of unidirectional carbon fiber reinforced epoxy composites under dry and wet reciprocating sliding KU Leuven
The role of water on the sub-surface degradation of unidirectional carbon fiber reinforced epoxy composite is examined. The correlation between the debonding of carbon fibers at the fiber–epoxy interface, and the wear behavior of the carbon fiber composite are discussed based on an in-depth analysis of the worn surfaces. We demonstrate that a reciprocating sliding performed along an anti-parallel direction to the fiber orientation under dry ...

Surface and Sub-Surface Degradation of Carbon Fiber Reinforced Composites under Reciprocating Sliding KU Leuven
Carbon fiber reinforced epoxy composites consist of two parts: a matrix and a reinforcement. In this thesis the reinforcement is unidirectional carbon fiber and the matrix is a thermoset polymer called epoxy. These composites are usually not applied for tribological purposes (friction, wear), although they have inherent great potential. The nature of the carbon fiber composite wear is very important, but also the risk of debonding occurring in ...
Surface damage of unidirectional carbon fiber reinforced epoxy composites under reciprocating sliding in ambient air KU Leuven
For many technical applications friction and wear are critical issues. Reinforced polymer-matrix composites are widely used under vibrating contact condition in various automotive and aerospace applications as well as in structural engineering. In this paper, the friction and wear of bulk epoxy and unidirectional carbon fiber reinforced epoxy composite have been investigated under reciprocating sliding against either alumina or stainless steel ...
