Abstract
In various aspects, reinforced composite filaments, methods of making reinforced composite filaments, and methods of producing reinforced composite filament are all provided herein. The reinforced composite filaments can include a thermoplastic polymer matrix having dispersed therein reinforcing fibers composed of a thermotropic liquid crystalline polymer. In some aspects, the thermoplastic polymer matrix is chosen such that a processing temperature for the thermoplastic polymer matrix is below a melting temperature of the thermotropic liquid crystalline polymer. In some aspects, the thermotropic liquid crystalline polymer is chosen such that a solidification temperature of the thermotropic liquid crystalline polymer is below an upper processing temperature of the thermoplastic polymer matrix. The filaments can be used for fused deposition manufacturing of a variety of parts, especially for the automotive and other industries.
