Abstract
A morphologlcal study was performed to determine the volume fraction a nd the aspect ratio of shear-induced fibers from a thermotropic liquid crystalline polymer (LCP) in a polycarbonate (PC) matrix. A set of mi cromechanical models was then applied to estimate the elastic modulus of LCP fibers (E(j)) in a LCP(20 wt%)/PC blend. The dependence of the composite modulus (E(t)) of the blend on sample dimensions was predict ed. The effects of different injection molding conditions on fiber asp ect ratio, E(t) and E(j), were examined.
