Resumen

Introducción: Este estudio investiga las características de la dureza Shore-D y la rugosidad superficial de seis especies de maderas tropicales: Canelo (Nectandra spp.), Limbali (Gibertiodendron dewevrei), Difou (Morus mesozygia), Curupay (Anadenanthera macrocarpa), Ebiara (Berlinia bracteosa) y Zwarte kabbes (Diplotropis martiusii), con el objetivo de evaluar su idoneidad para aplicaciones de alto rendimiento.

Objetivo: Evaluar cómo la especie de madera y el proceso de lijado influyen en las propiedades mecánicas y la calidad superficial de las maderas tropicales seleccionadas.

Métodos: Las muestras fueron acondicionadas y lijadas utilizando abrasivos de diferentes granulometrías (80, 100, 120, 150 y 180). Se evaluaron los parámetros de rugosidad superficial Ra, Rq y Rz, así como la dureza Shore-D. Los datos se analizaron estadísticamente mediante ANOVA y la prueba de Duncan.

Resultados: El análisis estadístico reveló que el tamaño del grano del abrasivo influyó significativamente en la rugosidad superficial (p < 0,001), siendo las lijas más finas las que produjeron superficies más lisas. La especie de madera también tuvo un efecto significativo tanto en la rugosidad como en la dureza. El lijado tuvo el mayor impacto en los parámetros Ra, Rq y Rz. Ebiara presentó la superficie más lisa, mientras que Curupay mostró la mayor dureza (74,65).

Conclusión: La rugosidad superficial está influenciada principalmente por la granulometría del lijado, mientras que la dureza está determinada por la especie de madera. Los resultados destacan la importancia de adaptar los procedimientos de lijado al tipo de madera para optimizar la calidad superficial y el rendimiento mecánico en aplicaciones industriales y decorativas.
