Abstract
In this paper, through the morphological study of surface-treated samples and by using the well-known Halpin-Tsai equations, the aspect ratio and the elastic modulus of the shear-induced fibers from a thermotropic liquid crystalline polymer (LCP, Vectra A950) in a polycarbonate (PC) matrix were determined. Based on Cox's classic theories about the development of disperse liquid drops in suspending medium, the deformation mechanism of the LCP phase in the thermoplastic matrix was quantitatively or semi-quantitatively studied. The relationships among the viscosity ratio of LCP and PC, Weber number and the fiber development are given.
