| Research Abstract |
We considered the capillary extrusion problems that can be seen in polymer extrusion process. According to the extrusion experimental results of polymer/VGCF(Vapor-grown carbon fiber) composite melt, the diameter of the extrusion decreased with an increase of VGCF contents. According to melt rheology measurement results of polymer/VGCF composite, this phenomenon would contribute the elongational flow property. Then, we calculated the extrusion flow problem by using the Phan-Thien Tanner model that can set the property of elongational flow individually. As the results, the calculation results agreed with the experimental data quantitatively. The whole obtained results in this study imply that the useful flow simulation for polymer/VGCF nanocomposite melts can be carried out by using the viscoelastic fluid model in existence.
