Finite element modeling of indentation and adhesive wear in sliding of carbon fiber reinforced thermoplastic polymer against metallic counterpart Ghent University
Shear strengthening of precast prestressed I-girders using carbon fiber reinforced polymers and in-fill concrete blocks Ghent University
A DNN-based image retrieval approach for detection of defective area in carbon fiber reinforced polymers through LDV data Ghent University
Carbon fiber reinforced polymer (CFRP) materials, due to their specific strength and high consistency against erosion and corrosion, are widely used in industrial applications and high-tech engineering structures. However, there are also disadvantages: e.g. they are prone to different kinds of internal defects which could jeopardize the structural integrity of the CFRP material and therefore early detection of such defects can be an important ...
Barely visible impact damage detection in aerospace-grade carbon fibre reinforced polymer components with optical fibre sensors Vrije Universiteit Brussel
Optical fibre-based sensors have shown great potential for damage detection in composite aircraft components, but demonstrations of this technology have been mostly limited to laboratory experiments carried out in ideal environmental conditions. In my PhD research, I take this technology to the next level and deal with different practicalities that need to be considered when working in actual aerospace-grade environments. First, I have ...
Numerical analysis of concrete beams retrofitted with carbon fibre reinforced polymer under impact loading Ghent University
Embedded fiber bragg gratings in photonic crystal fiber for cure cycle monitoring of carbon fiber-reinforced polymer materials Ghent University
We report on the use of a fiber Bragg grating (FBG) based sensor written in a photonic crystal fiber (PCF) to monitor the cure cycle of composite materials. The PCF under study has been specifically designed to feature a high phase modal birefringence sensitivity to transverse strain and a very low sensitivity to temperature. We exploit these particular properties to measure strain inside a composite material in the out-of-plane direction. The ...
Modelling of thermoplastic polymer failure in fiber reinforced composites KU Leuven
The paper proposes a material model that characterizes the plastic behavior and damage accumulation in thermoplastic matrix in dependence on the type of the stress state that the matrix undergoes during loading. The model is applied (1) to the case of transversal tension loading of periodic cells of unidirectional composites with random spacing of fibers and (2) to the analysis of interface failure during fiber pull out tests. The first case ...
Effect of interleaved polymer nanofibers on the properties of glass and carbon fiber composites Ghent University
Electrospun (polymeric) nanofibers are proved to be one of the most successful toughening techniques for improving the damage resistance of structural fiber-reinforced polymer composite laminates. In the past decade, we have seen a steady increase in published research papers and industrial interest on this topic. In this chapter, we highlight the major findings related to the use of electrospun nanofiber toughening veils together with a concise ...
