Abstract
This work proposes a new methodology to determine transverse permeability of reinforcements used in resin infusion processes. A new design for the experimental mold is developed not based on a rectilinear flow, as seen in literature, but on a two-dimensional flow. Coupled with the laboratory experiment, a numerical simulation is used to calculate the transverse permeability. In the numerical simulation, resin advance is tracked over the transverse direction and time needed to reach a specific location is compared with laboratory measurements. This work actually reports the first studies about this new method and laboratory experiments have not yet been performed. The needed laboratory data is emulated, however this simplification does not compromise the study presented in the article. Main goal is to develop a simple and easier to assemble experiment for the transverse permeability determination. Preliminary results have shown that proposed method is a viable alternative for the traditional transverse permeability methods. Direct comparison between numerical and experimental result presented an difference (error) smaller than 5%.
