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 envelhecimento e propriedades mecânicas de compósito epóxi reforçado ...
Valença, Silvio LeonardoThe epoxy resin has a widespread use in the manufacture of polymer composites to obtain various elements of structural engineering. The overall objective of this research is to evaluate the effect of reinforcing fabric architecture fiber-based Kevlar 49 and glass S on the mechanical performance of composites with epoxy matrix. It was observed that the mechanical performance of the epoxy resin and the composite,...
Avaliação da tensão interfacial entre petróleo parafínico e superfícies com res...
Valença, Silvio LeonardoOil is a very complex chemical system, as for instance, the paraffinic type which was considered as a fluid to be evaluated in this scientific paper, trough the static interfacial tension with the surfaces of the API 5L grade B conduction pipe and the EPOXY and EPOXY M resins. The paraffinic oil produced in the 7-PIR-244D-AL well, which is located in the producing field of Pilar in the state of Alagoas, present...
