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 ...

3D spacers enhance flow kinetics in resin transfer molding with woven fabrics

Véronique Michaud, Baris Çaglar, Damiano Salvatori

Impregnation time in Resin Transfer Molding (RTM) is directly proportional to resin viscosity and inversely proportional to fabric permeability, limiting the use of high-viscosity resins with conventional reinforcements. In this study, we show how to reduc ...
