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 LTD2022Manufacturing and toughening effects on the material properties of wind turbine blade adhesives
Anastasios Vassilopoulos, Dharun Vadugappatty Srinivasan
Hybrid adhesives can be developed using commercially available adhesive materials and customized to the required loading conditions. In this paper, SPABONDTM 820HTA (non-toughened) and SPABONDTM 840HTA (toughened) adhesives are hybridized by two strategies ...
ELSEVIER SCI LTD2022Multiscale microshaping of functionally graded polymer-derived SiCN ceramics
Polymer-derived ceramics (PDCs) exhibit excellent properties and are compatible with many shaping techniques due to the liquid character of the preceramic polymers (PCPs). Furthermore, their properties are adjustable by modifying the precursor composition ...
EPFL2022Resin Transfer molding of High-Fluidity Polyamide-6 with modified Glass-Fabric preforms
Véronique Michaud, Damiano Salvatori, Baris Çaglar, Robin Samuel Trigueira, Colin Gomez
In Resin Transfer Molding (RTM), resin precursors of thermoset or, more recently, thermoplastic polymers are generally employed, raising issues related to the chemical reaction taking place during and after part processing. In this study, already polymeriz ...
2021Kinematic and mechanical response of dry woven fabrics in through-thickness compression: Virtual fiber modeling with mesh overlay technique and experimental validation
Véronique Michaud, Baris Çaglar, Lode Geeraard Daelemans
The through-thickness compressive behavior of fabric reinforcements is crucial in liquid composite molding manufacturing processes. Predictive simulations of the compressive response are thus necessary to enable a virtual processing workflow. These are com ...
