Thermoplastic composites reinforced with liquid crystalline polymer (lcp) fibers of a micrometer-size diameter have been described. a novel approach presented in the paper is based on the modification of interface by means of compatibilization. interfacial adhesion in lcp reinforced composites was evaluated qualitatively by using a scanning electron microscopy. interfacial tension values were predicted by good-girifalco method and measured by the approach of wu and palierne. compatibilization causes a decrease in the interfacial tension, which has been related to an enhancement in the mechanical strength of lcp composites.
