A numerical simulation of the resin film infusion process

Numerical simulation of flow processes in composites manufacturing

“…This modified Darcy's law can be integrated into the mass conservation equation leading to a new governing equation (Park and Kang, 2003). This modified Darcy's law can be integrated into the mass conservation equation leading to a new governing equation (Park and Kang, 2003).…”

“…It should be kept in mind that all the terms including the fiber velocity should be considered, however, if the principal direction of resin flow and that of fiber motion coincide with each other, such as in the case of the RFI process (Park and Kang, 2003). For example, we can see that the fiber swells in the thickness direction and the resin also flows in the same direction in Figure 15.24 (Park and Kang, 2003 In the literature, the governing equation for the vacuum infusion process has been represented by different formulations.…”

Manufacturing and Processing of Polymer Composites

“…RFI is mainly used in the aerospace industry and provides good mechanical properties due to curing at elevated temperatures. Dry spots are rarer than for VARTM and SCRIMP processing due to resin propagating in thickness direction only [90][91][92]. …”

Hydro-mechanical loading and compressibility of fibrous media for resin infusion processes

“…The differentials of pressure and compaction stress in the z direction are taken into account in the modelling of the RFI process proposed by Ouahbi et al [6]. A Model using similar basis was also proposed by Park and Kang [7]. Independently of simulating the RFI process, the computer code proposed by Ouahbi et al [6] was developed to predict the evolution of the reinforcement's thickness submitted to various combination of hydraulic and mechanical loading (Hydro-Mechanical loading) as a function of time.…”
