Abstract

In the present paper, press molding for thermo-plastic resin toughened by carbon nanofiber were discussed. Polycarbonate (PC) and vapor grown carbon nanofiber (VGCF) are used for the resin matrix and the reinforcement. In order to investigate and simulate the process molding process of the PC/VGCF composite by finite element method, the constitutive equation, namely thermo-viscoelastic property of the composites are required. The relaxation modulus (Master curve) and shift factor to characterize it's thermo-viscoelastic behavior were estimated by unidirectional compression creep test in this paper. The relaxation modulus for the composite were approximated by the discretized series form using generalized Maxwell model. Demonstrations for press molding using V-shape die has been carried out. Experimental results of the height of the V-shape and those obtained by FEM analysis were comparead and disscussed in detail to confirm the validity of the present numerical method based on thermo-viscoelastic theory.
