Optimized Design of an ECAP Die Using the Finite Element Method for Obtaining Nanostructured Materials por Ponce Peña, Patricia, López Chipres, Edgar, García Sánchez, Edgar, Escobedo Bretado, Miguel Ángel, Ochoa Salazar, Brenda Xiomara, González Lozano, María Azucena

“…To perform this, six different configurations were used in the design of the die’s channel for ECAP (equal channel angular pressing) to obtain nanostructure materials and to optimize the process. Thanks to simulation performed with FEM, it is possible to study the homogeneity in the deformation due to the variation of conditions affecting directly the material being processed using the ECAP technique, such as the friction coefficient, extrusion speed, and mainly the die’s channel geometry being utilized in the ECAP process. …”

Carbon fiber recovery using subcritical and supercritical fluids for chemical recycling of thermoset composite materials por Morales Ibarra, Rodolfo

“…In this research, benzyl alcohol and water in subcritical and supercritical conditions, with and without addition of tripotassium phosphate (K3PO4) as a decomposition reaction catalyst, were used to recover carbon fibers from composite materials for potential reuse in high performance components; while, in the literature review, the composite materials and their manufacturing processes were revisited, as well as the legal implications of end-of-life composite components, justifying the need for a thermoset composite materials recycling research project. …”
