Resumen


Este trabajo es un estudio sobre paneles acústicos fabricados con granos de corcho procedentes de subproductos de tapones para su empleo como techos suspendidos, proporcionando una alternativa sostenible y ecológica a los materiales de construcción tradicionales. Los granos de corcho se aglutinaron con una resina epoxi de base acuosa y resinas acrílicas. Los paneles obtenidos se sometieron a pruebas acústicas y mecánicas. Los resultados mostraron valores de absorción acústica media cercanos a 0.50 y una resistencia a la flexión aceptable para su uso como placas de techo. Por lo tanto, este tipo de paneles de base biológica podrían utilizarse como productos alternativos a los materiales tradicionalmente empleados para aplicaciones de control del ruido en el interior de espacios.
