Visualization and modelling of dynamic flow in fibrous preforms for liquid composite molding

Helena Luisa Teixido Pedarros

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 ...

Capillary 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 ...

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

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

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 ...

Textile Reinforced Concrete (TRC) is a cementitious composite material where a carbon or glass fabric is embedded as reinforcement. The use of TRC allows building thin and light structures, with reduced concrete covers and an enhanced durability due to the ...

ELSEVIER SCI LTD2020

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 ...

Experimental research on Textile Reinforced Concrete for the development of design tools

Aurelio Muttoni, Miguel Fernández Ruiz, Patrick Lorenzo Valeri

Due to the limited construction experiences as well as to the absence of clear and consolidated design provisions for design of Textile Reinforced Concrete (TRC), the application of this material in practice is still very limited. In this paper, the result ...

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 ...
