Abstract
In this paper, through the morphological study of surface-treated samp les and by using the well-known Halpin-Tsai equations, the aspect rati o and the elastic modulus of the shear-induced fibers from a thermotro pic 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 deforma tion mechanism of the LCP phase in the thermoplastic matrix was quanti tatively or semi-quantitatively studied. The relationships among the v iscosity ratio of LCP and PC, Weber number and the fiber development a re given.
