Abstract
A glass fiber strand impregnated with a liquid crystal polymer and an aqueous slurry composition useful for producing the liquid crystal polymer impregnated glass fiber strand are disclosed. The aqueous slurry composition includes a liquid crystal polymer resin powder and a thickener material. The slurry composition is applied to the glass fiber surfaces during the fiber forming process. Coupling agents, surfactants or lubricants material may optionally be added to the slurry composition. One embodiment of the slurry composition includes a polyethylene oxide binder material and a melt spinnable liquid crystal polyester which is optically anisotropic in the melt phase.
