Towards standardisation of the out-of-plane permeability measurement for reinforcement textiles

Véronique Michaud, Jacobus Gerardus Rudolph Staal, Helena Luisa Teixido Pedarros

In the collaborative effort towards standardisation of out-of-plane permeability measurement, an international benchmarking exercise was carried out whereby 19 participants worldwide were instructed to measure the out-of-plane permeability following a numb ...

Self-catalysed frontal polymerisation enables fast and low-energy processing of fibre reinforced polymer composites

Véronique Michaud, Baris Çaglar, Jacobus Gerardus Rudolph Staal

Frontal polymerisation has the potential to bring unprecedented reductions in energy demand and process time to produce fibre reinforced polymer composites. Production of epoxy-based fibre reinforced polymer parts with high fibre volume content, commonly e ...

Three-dimensional micro-CT images of UV-frozen flow fronts recorded at different flow regimes

Véronique Michaud, Jacobus Gerardus Rudolph Staal

Segmented micro-CT images of flow fronts produced by UV-flow freezing. Front morphologies correspond to capilary-dominated, equilibrated and viscous-dominated flow regimes. ...

Strategies for energy-efficient frontal polymerisation processing and microstructural evaluation of fibre reinforced composites

Jacobus Gerardus Rudolph Staal

Liquid composite moulding methods are widely applied for manufacturing of fibre reinforced polymer (FRP) composites and consist of two main stages: impregnation of fibrous reinforcements by a liquid monomer resin and curing of this resin. This thesis work ...

Thermal management in radical induced cationic frontal polymerisation for optimised processing of fibre reinforced polymers

Véronique Michaud, Baris Çaglar, Jacobus Gerardus Rudolph Staal

Radical induced cationic frontal polymerisation (RICFP) is considered a promising low energy method for processing of fibre reinforced polymers (FRPs). Optimisation of the local heat balance between reinforcement, epoxy resin and the surrounding mould is r ...

Simulations of Radical Induced Cationic Frontal Polymerisation under different applied initial temperatures, trigger times and glass fibre contents

Véronique Michaud, Jacobus Gerardus Rudolph Staal

Videos demonstrating simulations of Radical Induced Cationic Frontal Polymerisation in a 2D finite difference model composed of a insulating mould surrounding a cavity. The following acronyms are used in the filenames: PP: Pure polymer (no fillers) GF: Gla ...

Capillary Effects in Fiber Reinforced Polymer Composite Processing: A Review

Véronique Michaud, Baris Çaglar, Jacobus Gerardus Rudolph Staal, Helena Luisa Teixido Pedarros

Capillarity plays a crucial role in many natural and engineered systems, ranging from nutrient delivery in plants to functional textiles for wear comfort or thermal heat pipes for heat dissipation. Unlike nano- or microfluidic systems with well-defined por ...

In-series sample methodology for permeability characterization demonstrated on carbon nanotube-grafted alumina textiles

Véronique Michaud, Baris Çaglar, Jacobus Gerardus Rudolph Staal

In-plane permeability of small area (100 × 50 mm) alumina fiber woven fabrics grafted with aligned carbon nanotubes (CNT) was quantified by placing them in series with a glass mat of known permeability during a flow experiment. The methodology was first va ...
