Resin Transfer molding of High-Fluidity Polyamide-6 with modified Glass-Fabric preforms

Véronique Michaud, Robin Samuel Trigueira, Colin Gomez, Damiano Salvatori, Baris Çaglar

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 ...

Out-of-plane permeability measurement for reinforcement textiles: A benchmark exercise

Véronique Michaud, Amaël Maximilien Cohades, Damiano Salvatori, Baris Çaglar

The out-of-plane permeability of two glass fibre fabrics was measured by 26 institutions using silicone oil as a test fluid. Participants in this study were free to select the test procedure, specimen dimensions and data analysis method, provided that test ...

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

Véronique Michaud, Damiano Salvatori, Baris Çaglar

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 ...

Permeability and capillary effects in a channel-wise non-crimp fabric

Véronique Michaud, Damiano Salvatori, Baris Çaglar, Helena Luisa Teixido Pedarros

Flow properties are investigated for a non-crimp glass fabric with large meso-channels designed for high-permeability, as compared to glass twill woven fabric. Saturated and unsaturated permeability are measured through in-plane, unidirectional, constant-p ...

Strategies for faster impregnation in melt thermoplastic resin transfer molding process

Damiano Salvatori

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 ...

In-plane permeability distribution mapping of isotropic mats using flow front detection

Véronique Michaud, Damiano Salvatori, Baris Çaglar

In-plane permeability of textile fabrics is often characterized by one-dimensional rectilinear flow experiments, displaying limitations related to potential race-tracking effects and the need to run experiments at several fiber volume fractions. We propose ...
