Evaluación de las propiedades físicas de material compuesto elaborado con bambú (Guadua angustifolia Kunth) y polipropileno

Abstract

En años recientes, se ha incrementado el uso de los compuestos termoplásticos reforzados con materiales lignocelulósicos, debido a la creciente necesidad de las industrias de la construcción y automotriz. Esta conducta es impulsada por varios factores de mercado y de la sociedad, como la demanda por productos amigables con el medio ambiente, la regulación estricta del uso de los químicos, cambios en el estilo de vida. Las fibras y harina de madera se usan comúnmente en los materiales compuestos, pero se pueden sustituir con otras naturales como el lino, sisal, palma, fique, yute, coco, bambú; la mayoría de ellos son desechos agro-industriales. Se utilizaron partículas provenientes de la parte apical de cañas residuales de bambú (Guadua angustifolia) para la obtención de materiales compuestos de polipropileno (PP) reforzados, sin y con agente acoplante (anhidrído maléico de polipropileno-MAPP). La elaboración se hizo con el método de extrusión y moldeo por compresión, con tamaños de malla ASTM: -20/+40, -40/+60 y -60/+80; proporciones de mezcla bambú/plástico: 50/50, 40/60 y 30/70; y con 0 y 2 % de MAPP. En total se obtuvieron 18 formulaciones. Se evaluaron las siguientes propiedades físicas: contenido de humedad, densidad, absorción e hinchamiento. Los resultados muestran que los materiales presentaron los mejores valores con el tamaño de malla -60/+80, con la proporción de mezcla 30/70 y cuando contenían MAPP en su composición
