Fully flow modeling of resin infusion under flexible tooling using unstructured meshes and wet and dry compaction properties

A Strategy to Support Design Processes for Fibre Reinforced Thermoset Composite Materials

“…Expressions are fitted to the particular part geometry and fibre volume range considered in this work. Previous studies of Robitaille et al [35] and Kessels et al [19], demonstrate that the variation of the thickness of the part is related to the position of the flow front, decreasing from inlet to vents. Most of the expressions used for compaction have been unified in the work of Correia et al [9].…”

Numerical simulation of flow processes in composites manufacturing

“…If the resin is not gelled, the volume of preform continues to change even after the mold is completely filled with the resin. It has been reported in many references, that the comparison between the simulation results and the experimental data of the vacuum infusion mold-filling process, however, shows a great discrepancy (Kessels et al, 2007;Modi et al, 2009;Bayldon and Daniel, 2009;). During this postfilling stage, the resin inlet is closed, whereas the resin outlet or air vent may be either opened or closed according to the processing strategy.…”

“…Some modeling results are shown in Figures 15.25 and 15.26 (Park and Saouab, 2009). On the other hand, finite element simulation of the vacuum infusion process has been extensively performed for the complex mold-filling process (Kang et al, 2001;Han et al, 2000;Kessels et al, 2007). On the other hand, finite element simulation of the vacuum infusion process has been extensively performed for the complex mold-filling process (Kang et al, 2001;Han et al, 2000;Kessels et al, 2007).…”

Resin infusion/liquid composite moulding (LCM) of advanced fibre-reinforced polymer (FRP)

“…This can be done by using LVDTs [121][122][123][124] or laser gauges [125] but these techniques will only provide discrete point measurements. By mounting a laser on a rail it is possible to monitor the thickness of a line along the length of a part [126], but for a true measurement of the thickness variations on the whole surface of the mould it is possible to use a 3D laser scanner [127] or stereophotogrammetry [76,99,128,129].…”
