“…However, the most commonly employed method remains the visual monitoring through a transparent mold [14,27]. In order to reduce the scatter and solve statistical equations described in the next section, it was recommended to measure multiple data points during testing.…”

Elsevier Vernet, N.; Ruiz, E.; Advani, S.; Alms, JB.; Aubert, M.; Barburski, M.; Barari, B.... (2014) Abstract:In this second international permeability benchmark, the in-plane permeability values of a carbon fabric were determined by 12 participants worldwide. One other participant also investigated the deformation of this fabric. The aim of this work was to obtain comparable results in order to make a step towards standardization of permeability measurements of fibrous reinforcements. The procedures used by most participants were according to the guidelines defined for this exercise after the first benchmark. Unidirectional injections in three in-plane directions of the fabric were conducted to determine the unsaturated in-plane permeability tensor. Parameters such as fiber volume fraction, injection pressure and fluid viscosity have been fixed in order to minimize sources of scatter. The comparison of the results from each participant was encouraging. The scatter between data obtained while respecting the test guidelines was close to the scatter of the setups themselves. A slightly 2 higher dispersion was observed when some parameters differed from the recommendations.Overall, a good correlation is observed between all the results of this exercise.

“…It has been known that complicated preform structure induces a dual-scale flow behavior: microscopic flow and macroscopic flow [6][7][8][9][10]. A direct result from this flow competition is entrapment of voids within the fabric [11], especially micro voids formed due to the microscopic capillary effects and low permeability of the fiber tows [12].…”

“…The lower and upper bounds for b and K were specified as 0 to 1, and 1 Â 10 À11 m 2 to 1 Â 10 À8 m 2 , respectively. The permeability bounds were based on the usual values reported for fabrics similar to those used in the present work (Luo et al, 2001;Lekakou et al, 1996;Hoes et al, 2002).…”
