Abstract

A thermotropic liquid crystalline polymer matrix having wollastonite fibers incorporated therein for reinforcement to prepare a molding compound. The wollastonite fibers have an average aspect ratio of greater than 3 to 1, and may be coated on their surface with a coupling agent to produce better bonding between the fibers and the thermotropic liquid crystalline polymer. The surface abrasion of an article produced from a blend of wollastonite with a thermotropic liquid crystalline polymer is reduced as compared to that of unfilled polymer.
