Evaluación de propiedades físicas de bioplásticos termo-comprimidos elaborados con harina de yuca
Resumen
Las innovaciones tecnológicas en materiales plásticos elaborados con recursos naturales renovables requieren el conocimiento de sus propiedades y características funcionales para identificar sus potencialidades y ventajas competitivas frente a los materiales elaborados con recursos no renovables. En este trabajo, se estudió el comportamiento de las propiedades mecánicas, densidad y color (L* a* y b*) en bioplásticos elaborados con harina de yuca de variedad MPER-183 gelatinizada, reforzados con fibra de fique. Los bioplásticos fueron obtenidos mediante la técnica de moldeo por compresión variando la presión (0, 20 y 40 psi) y la temperatura (180, 190 y 200°C). Las variables temperatura y presión de compresión afectaron significativamente (p<0,05) las propiedades mecánicas, el color y la densidad de los bioplásticos, identificando las condiciones de temperatura de 180°C y presión de 0 psi como las más favorables para L*, a* y b*, altos valores de esfuerzo de flexión, modulo elástico de flexión y baja densidad, mientras que la temperatura de 190°C y presión de 0 psi, fueron apropiadas para obtener altos valores de esfuerzo de tensión y modulo elástico de tensión.
