Relation between the Epoxy Resin Curing and the Mechanical Properties of the Co...
Valença, Silvio Leonardo; Sussuchi, Eliana Midori; Griza, Sandro; Valença, Gabriela Oliveira; Santos, Cochiran Pereira dosDGEBA has a widespread use in the manufacture of polymer composites to obtain different elements of structural engineering. The mechanical properties can be predicted by the physical-chemical knowledge of the processing conditions of the resin components, and of their storage and handling conditions. This study aimed to characterize the functional groups, as well as the curing behavior of a batch of resin with ...
Estudo de variáveis de processo e da cinética de sinterização de materiais util...
Santos, Cochiran Pereira dosThis study aims a reasoned study on the physical, chemical, mineralogical and microstructural characterization of four clay raw materials of the state of Sergipe, three of them never previously studied and evaluates its potential for use in the production of ceramic tiles. We analyzed the influence of process variables granulometry, pressing, ceramic formulation, heating rate and maximum firing temperature for ...
Síntese e caracterização de NiFe2O4 e efeitos da dopagem na magnetização de sat...
Santos, Cochiran Pereira dosThe ferrites are a wide class of ferrimagnetic materials with great technological importance and are studied extensively for many decades. Their remarkable magnetic characteristics make it an element often used in induction transformers by his high magnetic permeability, high values of saturation magnetization and low coercivity, resulting in smaller losses in their hysteresis loops. In this work were character...
