INVESTIGATION OF FIBER ORIENTATION AND MATERIAL RELATION FOR AUTOMOTIVE RADIATOR CARRIER
 
In recent years, studies have been carried out for weight reduction in various areas. The automotive industry includes the most up-to-date innovations in these studies. Based on this, composite structures get involved in regions where plastic doesn’t meet sufficient mechanical conditions. Since there is no single modeling method for the design and analysis of composite structures, the results between the virtual and physical environments vary. The aim of this study is to define a new material for passenger and commercial vehicle radiator carriers with long glass fiber material (PPLGF40) using Digimat, Ls-Dyna and Moldflow programs. For these processes, material verification was accomplished in Digimat-MX program interface, respectively. By using Moldflow analysis, the movements of the fiber reinforcements in the material in the mold and the regional fiber densities were determined. Besides, the data received from Moldflow was processed on top of the current Ls-Dyna analysis model from the Digimat-MAP interface. A new analysis model was created by including the data we obtained from the MX and MAP interfaces in the Digimat RP interface into the existing Ls-Dyna model. Related results of the PPLGF40 material with the values obtained from the tensile test and the analysis results of the material obtained from the Digimat program were compared. When the conclusions were examined, fractured regions were defined in different regions for both materials. When the results were compared with the physical test, the correlation was obtained between the Digimat program and the physical test.
