Abstract

SE PRESENTA UN METODO PARA DETERMINAR LA CALIDAD DE DISPERSION DE LAS FIBRAS DE CRISTAL EN UNA CAPA DE UNA PROFORMA DE RESINA TERMOPLASTICA QUE COMPARA LA LONGITUD CARACTERISTICA MEDIA DE LOS MANOJOS DE FIBRA DE CRISTAL EN LA CAPA DE LA PROFORMA CON UN VALOR PREDETERMINADO INDICATIVO DE LA DISPERSION DE LAS FIBRAS DE CRISTAL. LA CAPA DE LA PROFORMA DE RESINA TERMOPLATICA CARACTERIZADA POR ESTE METODO COMPRENDE UNA PLURALIDAD DE FIBRAS DE CRISTAL INDIVIDUALES Y ALGUN GRADO DE MANOJOS DE FIBRA DE CRISTAL NO DISPERSOS INTIMAMENTE MEZCLADOS CON UNA PLURALIDAD DE FIBRAS TERMOPLASTICAS DISCRETAS. LAS FIBRAS DE CRISTAL SE INTRODUCEN EN LA MEZCLA CON UNA LONGITUD DE ENTRE 1 Y 8 CMS. DESPUES DE LA MEZCLA, ALGUNOS MANOJOS DE FIBRAS DE CRISTAL SE ROMPEN, Y PERMANECEN ALGUNOS MANOJOS RESIDUALES DE FIBRA DE CRISTAL. LA CAPA DE LA PROFORMA TIENE UNA DISPERSION ACEPTABLE, TIENE MANOJOS RESIDUALES DE FIBRA DE CRISTAL QUE TIENE UNA LONGITUD MEDIA APARENTE INFERIOR A 1.365 MM.
