The present invention relates to continuous processes for making composite fibers from aramid polymers. The process includes : continously combining an anisotropic polymer solution of an aramid polymer and an isotropic solution of a second polymer to form a combined polymer solution ; passing the combined polymer solution through at least one static mixer to form a spin dope ; and extruding the spin dope through a spinneret to form a composite fiber. The process prduce fibers that are useful in a variety of applications, including reinforcing elastomeric materials.

L'invention concerne des procédés continus de fabrication de fibres composites à partir de polymères aramides. Ces procédés sont destinés à produire des fibres utiles dans diverses applications, notamment dans le renforcement de matériaux élastomères.
