Analytical Modeling of CRTM and RTM Processes. Part II : Applications to the Analysis of the Process
An analytical modeling of the manufacturing of a composite material plate by various processes RTM or CRTM was developed (Saouab et al., 2004). The work presented here is relative to the application of this modeling for the analysis and the control of these processes. In the first application a comparison is established between various scenarios applied to CRTM process. A parametric study concerning the influence of some parameters on material forming is presented. A detailed analysis will deal with manufacturing constraints such as an imposed fiber volume rate or a processability criterion. In the second application, concerning the same CRTM process scenario, the effects of a line injection and a central injection are compared. Finally, this two-stage CRTM manufacturing is compared with two others CRTM processes where two simultaneous stages occur.
