Complex engineering challenges are revealed in the wind industry; one of them is erosion at the leading edge of wind turbine blades. Water jet erosive wear tests on carbon-fiber reinforced polymer (CFRP) and glass-fiber reinforced polymer (GFRP) were performed in order to determine their resistance at the conditions tested. Vacuum Infusion Process (VIP) was used to obtain the composite materials. Eight layers of bidirectional carbon fabric (0/90°) and nine glass layers of bidirectional glass cloth were used to manufacture the plates. A water injection platform was utilized. The liquid was projected with a pressure of 150 bar on the surface of the specimens through a nozzle. The samples were located at 65 mm from the nozzle at an impact angle of 75°, with an exposure time of 10, 20 and 30 min. SEM and optical microscopy were used to observe the damage on surfaces. A 3D optical profilometer helped to determine the roughness and see the scar profiles. The results showed that the volume loss for glass fiber and carbon fiber were 10 and 19 mm³, respectively. This means that the resistance to water jet erosion in uncoated glass fiber was approximately two times lower than uncoated carbon fiber.

Una de principales causas de un desempeño mecánico deficiente en máquinas industriales, es la mala selección y calidad de los lubricantes, esto se deriva a la falta de comprensión de sus propiedades tribológicas. Por esta razón es importante complementar la información fisicoquímica de los lubricantes con los resultados de los ensayos tribológicos impactando directamente a la productividad y la eficiencia de los procesos industriales. Para determinar las propiedades tribológicas de lubricantes, en este trabajo se presenta el diseño conceptual de una plataforma de 4 bolas bajo las especificaciones de la norma ASTM D2266. Se aplicó la metodología de diseño de Nigel Cross, la cual aporta resultados para satisfacer las subfunciones requeridas y objetivos establecidos. El diseño conceptual se validó numéricamente con el software ANSYS, a partir del análisis de esfuerzos y deformaciones del bastidor, la sujeción de la bola y de la celda, manifestando la importancia del material aplicado al sistema para evitar fallas durante la operación.
