Abstract

SE DESCRIBE UNA TRAMA DE FIBRAS NO BOBINADAS Y POLIMERO DE MATRIZ TERMOPLASTICA QUE PUEDE PRODUCIR PROPIEDADES FISICAS MEJORADAS EN ARTICULOS MOLDEADOS CON ESTA TRAMA. TAMBIEN SE DESCRIBEN LA DISPERSION ACUOSA PARA PRODUCIR LA TRAMA Y LA TRAMA SECA EN FORMA DE LAMINADO DE TAL MANERA QUE PUEDE MOLDEARSE Y FORMAR ARTICULOS MOLDEADOS. LA TRAMA AÑADIDA A LAS FIBRAS Y EL POLIMERO DE MATRIZ TERMOPLASTICA TIENE UN POLIMERO TERMOPLASTICO QUIMICAMENTE MODIFICADO. ESTE MATERIAL PUEDE AÑADIRSE A LA TRAMA MEDIANTE ADICION DIRECTA A LA DISPERSION ACUOSA O POR LA PRESENCIA EN UN LIGADOR DE MALLA QUE SE APLICA A LA TRAMA. GENERALMENTE, LA CANTIDAD DEL MATERIAL TERMOPLASTICO QUIMICAMENTE MODIFICADO PRESENTE EN LA TRAMA ESTA EN UN MARGEN QUE OSCILA ENTRE 0.1 Y 20 POR CIENTO EN PESO DE LA TRAMA . CUANDO EL POLIMERO TERMOPLASTICO QUIMICAMENTE ACOPLADO SE AÑADE COMO UN LIGADOR DE MALLA, PUEDE ACOMPAÑARSE POR UN AGENTE ACOPLADOR DE ORGANO DONANTE DE ELECTRONES, UN AGENTE ESTABILIZADOR COMO POR EJEMPLO UNO O MASACIDOS CARBOXILICOS Y/O ANHIDRIDOS QUE PUEDEN SER MONOCARBOXILICOS, POLICARBOXILICOS, ALIFATICOS O CICLICOS. ADICIONALMENTE, EL LIGADOR DE MALLA PUEDE TENER UN POLIMERO FORMADOR DE PELICULA.
