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 ...
EPFL2023Visualization and modelling of dynamic flow in fibrous preforms for liquid composite molding
Nowadays, Liquid Composite Molding techniques are often used to manufacture high quality fiber reinforced composite parts at a relatively low cost. These involve an infiltration process, in which a liquid resin is forced to ingress into a dry fibrous porou ...
EPFL2023Novel tooling for direct melt impregnation of textile with variotherm injection moulding: Methodology and proof of concept
Véronique Michaud, Vincent Werlen, Christian Rytka
Thermoplastic compression resin transfer moulding coupled with injection moulding is an appealing process for the production of thermoplastic composites. However, its implementation at an industrial scale remains challenging as variotherm injection mouldin ...
SAGE PUBLICATIONS LTD2022Capillary Effects in Fiber Reinforced Polymer Composite Processing: A Review
Véronique Michaud, Jacobus Gerardus Rudolph Staal, Baris Çaglar, 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 ...
FRONTIERS MEDIA SA2022A life cycle analysis of novel lightweight composite processes: Reducing the environmental footprint of automotive structures
Véronique Michaud, Baris Çaglar, Vincent Werlen, Christian Rytka, Colin Gomez
In this study, three novel thermoplastic impregnation processes were analyzed towards automotive applications. The first process is thermoplastic compression resin transfer molding in which a glass fiber mat is impregnated in through thickness by a thermop ...
ELSEVIER SCI LTD2022Strategies for faster impregnation in melt thermoplastic resin transfer molding process
Continuous fiber thermoplastic composites are potential substitutes of steel in structural automotive components, since they combine fiber strength and rigidity with ductility, potential recyclability and low density of the thermoplastic (TP) matrix. Resin ...
EPFL2018Hybrid Processing of Thermoplastic Based Multimaterials
There is a growing interest in exploring novel material combinations and processing technology to manufacture complex 3D shaped polymer and composite structures. In the field of prosthetics and orthotics, this need is significant with additional challenges ...
EPFL2017Screening method for the onset of bonding of molten polyamide resin layers to continuous fiber reinforced laminate sheets
Thermoplastic polymer composites (TPC) with multiple fabric layers of continuous fiber reinforcement are laminate sheets designed to be thermally stamped and overmolded leading to low cycle times and thus high volume composite parts. Injection over-molding ...
2016Dynamic mechanical properties of epoxy/flax fibre composites
Pierre-Etienne Bourban, Fabien Duc
The mechanical and damping properties were measured for unidirectional, 0/90 and twill 2/2 flax fibre (FF) composites containing 40 vol% of fibres in an epoxy matrix. All composites were processed by resin transfer moulding. The influence of the impregnati ...
