An improved fabric is provided comprised of fusible and infusible fibers. The fusible fibers comprise thermotropic liquid crystal polymers (i.e., polymers which are capable of forming an anisotropic melt phase). When the liquid crystal fibers are heated, they fuse to adjacent infusible fibers without any substantial loss of the orientation which was imparted to the same during melt extrusion. A fabric of enhanced strength and stiffness is thus formed in comparison to a fabric which employs conventional thermoplastic polymers which do not form an anisotropic melt phase.
