| description |
In this work the mechanical properties variability under uniaxial compression and the abrasive wear through the cross section of thick-piece carbon-black reinforced acrylonitrile rubber (NBR) parts, was studied. It has to take into account that in these type of pieces, the vulcanized rubber properties heterogeneity causes a variability effect, due to its low thermal diffusivity. Abrasive wear tests under dry conditions were carried out, seeking to identify the relationship between abrasive wear resistance and mechanical properties under uniaxial compression, such as hardness and elastic modulus. The samples in delivery state were evaluated after the vulcanization process, then environmentally exposed during three months and finally UV aged.Environmental aging stiffens the NBR, but the samples wear resistance from the cross sectional area center, is diminished. Their elastic modulus decreased with the UV aging, but its effect on the wear resistance depends from the previous environmental aging. Their hardness did not show a relationship neither with the elastic modulus nor with the wear resistance, therefore, it should not be used as a property to select the NBR rubbers, subject to wear resistance. The information obtained allows to generate design criteria for nitrile rubber-based parts. |

Se realizaron ensayos de desgaste abrasivo en seco, buscando identificar la relación entre la resistencia al desgaste abrasivo y las propiedades mecánicas en compresión, como el módulo elástico y la dureza. Se evaluaron muestras en estado de entrega tras el proceso de vulcanización, luego expuestas al ambiente durante tres meses y, posteriormente, envejecidas en una cámara UV. El envejecimiento ambiental rigidiza los materiales estudiados, pero disminuye la resistencia al desgaste del material proveniente del núcleo de las piezas. El envejecimiento UV disminuyó el módulo elástico, pero su efecto sobre la resistencia al desgaste depende del estado de envejecimiento previo. La dureza no presentó una relación directa ni con el módulo elástico ni con la resistencia al desgaste, por lo cual no puede usarse como propiedad para la selección de cauchos NBR sometidos a desgaste abrasivo. La información obtenida permite generar criterios para el diseño de componentes basados en este tipo de cauchos.application/pdftext/htmlspaspaUniversidad Pedagógica y Tecnológica de Colombiahttps://revistas.uptc.edu.co/index.php/ingenieria/article/view/3849/3453https://revistas.uptc.edu.co/index.php/ingenieria/article/view/3849/4337Revista Facultad de Ingeniería; Vol. 24 No. 40 (2015); 67-80Revista Facultad de Ingeniería; Vol. 24 Núm. 40 (2015); 67-802357-53280121-1129NBR rubberuniaxial compression testsabrasive wearCaucho NBRPruebas de compresión uniaxialDesgaste abrasivoThick section acrylonitrile rubber parts mechanical properties under compression and abrasive wear resistancePropiedades mecánicas bajo compresión y resistencia al desgaste abrasivo de piezas gruesas de caucho acrilonitriloinvestigationinfo:eu-repo/semantics/articlehttp://purl.org/coar/resource_type/c_2df8fbb1info:eu-repo/semantics/publishedVersionhttp://purl.org/coar/version/c_970fb48d4fbd8a183http://purl.org/coar/version/c_970fb48d4fbd8a85http://purl.org/coar/access_right/c_abf100http://purl.org/coar/access_right/c_abf2Velásquez-Restrepo, Sandra MilenaGiraldo-Vásquez, Diego HernánZapata-Gallego, Natalia Trinidad001/14125oai:repositorio.uptc.edu.co:001/141252025-07-18 11:53:14.521metadata.onlyhttps://repositorio.uptc.edu.coRepositorio Institucional UPTCrepositorio.uptc@uptc.edu.co |
