TL;DR: In this paper, the results of a third benchmark exercise using in-plane permeability measurement, based on systems applying the radial unsaturated injection method, were presented, where 19 participants using 20 systems characterized a non-crimp and a woven fabric at three different fiber volume contents, using a commercially available silicone oil as impregnating fluid.

TL;DR: In this paper, the specific nature of flax fibres with respect to manufacturing of biocomposites (defined here as polymers reinforced by natural fibres) is discussed. And the important steps in the process which influence final properties are analyzed, including the plant development, retting, fibre extraction, fibre treatment, preform preparation, available manufacturing processes, the impregnation step, fibre cell wall changes during processing and fibre/matrix adhesion.

Permeability and capillary effects in a channel-wise non-crimp fabric
TL;DR: In this paper, a non-crimp glass fabric with large meso-channels designed for high permeability, as compared to glass twill woven fabric, is investigated for in-plane, unidirectional, constant-pressure flow experiments.

Wetting and swelling property modifications of elementary flax fibres and their effects on the Liquid Composite Molding process
Monica Francesca Pucci,Pierre-Jacques Liotier,David Seveno,C.A. Fuentes,Aart Willem Van Vuure,Sylvain Drapier +5 more
TL;DR: In this article, flax fibres were thermally treated, to prove that modifying wetting and swelling properties of fibres changes the flow during LCM processes and thus could enhance the final material health of composite parts.

Wetting: statics and dynamics
TL;DR: In this paper, the authors present an attempt towards a unified picture with special emphasis on certain features of "dry spreading": (a) the final state of a spreading droplet need not be a monomolecular film; (b) the spreading drop is surrounded by a precursor film, where most of the available free energy is spent; and (c) polymer melts may slip on the solid and belong to a separate dynamical class, conceptually related to the spreading of superfluids.

TL;DR: In this international permeability benchmark exercise, in-plane permeability data for two reinforcement fabrics, obtained using a total of 16 different experimental procedures, were compared to find the main source of scatter in results from different procedures is related to human factors.

Influence of chemical treatments on surface properties and adhesion of flax fibre-polyester resin
TL;DR: In this paper, the influence of the chemical treatment on the surface tension of flax fibres investigated by wettability measurements was investigated by infrared microspectroscopy and finally on the adherence of resin microdrops was probed by a microbond test.

TL;DR: In this article, a simple apparatus was designed and constructed capable of measuring the unsteady-state permeability and the capillary pressure simultaneously in a simulated composite impregnation experiment.
