Abstract

UN METODO PARA FORMAR FIBRAS DISCRETAS FUERTES HILANDO UNA SOLUCION DE POLIMERO A TRAVES DE UNA HILERA. UN FLUIDO GASEOSO SE INYECTA EN PARALELO DENTRO DE UN NUCLEO DE LA SOLUCION DE POLIMERO ANTES DE PASAR A TRAVES DE LA HILERA. LA CIZALLA FUERTE FUERZA EL FLUIDO GASEOSO A EJERCER SOBRE LA SOLUCION DE POLIMERO QUE HACE QUE LAS FIBRAS DISCRETAS FUERTES ALTAMENTE ORIENTADA PRODUZCAN INTERMITENTEMENTE A TRAVES DE LA HILERA FIBRAS CONTINUAS.
