A numerical investigation of the resin flow front tracking applied to the RTM process
Souza, Jeferson Ávila; Rocha, Luiz Alberto Oliveira; Amico, Sandro Campos; Vargas, José Viriato Coelho (2011) [Journal article]Resin Transfer Molding (RTM) is largely used for the manufacturing of high-quality composite components and the key stage during processing is the resin infiltration. The complete understanding of this phenomenon is of ... -
Sulfonation and characterization of styrene-indene copolymers for the development of proton conducting polymer membranes
Becker, Cristiane Miotto; Biagini, Amanda Bertolo; Forte, Maria Madalena de Camargo; Amico, Sandro Campos; Vargas, José Viriato Coelho; Azambuja, Denise Schermann (2012) [Journal article]The aim of this work is to obtain polymer precursors based on styrene copolymers with distinct degrees of sulfonation, as an alternative material for fuel cell membranes. Acetyl sulfate was used to carry out the sulfonation ...
