Metallization of carbon fiber reinforced polymers: Chemical kinetics, adhesion, and properties KU Leuven
© 2016 In the present study, we investigate different surface pretreatments and their influence on a subsequent surface metallization. A direct liquid injection metalorganic CVD (DLI-MOCVD) process is presented for the low temperature metallization of composites, ultimately aiming at the surface functionalization of 3D parts. The process involves the organometallic precursor Cu(I) hexafluoroacetylacetonate 2-methyl-1-hexene-3-yne (hfac)Cu(MHY). ...
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 ...

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 ...
Embedded fiber bragg gratings in photonic crystal fiber for cure cycle monitoring of carbon fiber-reinforced polymer materials Universiteit Gent
Carbon nanotube-grafted carbon fiber polymer composites: Damage characterization on the micro-scale KU Leuven
Multiwall carbon nanotubes (CNTs) e carbon fibers (CFs) hybrid materials were produced by directly growing CNTs on CFs by means of chemical vapor deposition. For the latter, the oxidative dehydrogenation reaction of C2H2 and CO2 was applied, which allows growing CNTs without damaging the CF surface. Uni-directional nano-engineered carbon fiber reinforced composites (nFRCs) were fabricated by impregnating these hybrid materials with epoxy. The ...
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 ...
