Epoxy systems are widely applied as adhesives in the aerospace industry. They have excellent adhesion properties, however, being thermosetting, epoxy show fracture brittleness characteristics. Polysulfide and polymercaptans good options to increase flexibility of adhesive. Thermal analysis techniques generally used evaluate curing degree systems. In most cases, when infrared (IR) is used, it employed qualitatively. This paper presents reaction study a DGEBA prepolymer with diethylenetriamine...
Insulations for rocket motors such as Flexible Thermal Protections (FTPs) and Rigid Protection (RTPs) act thermal barriers against the hyperthermal environment from solid propellant combustion. FTPs present dual function: to extend RTPs performance, attenuate contraction. used in Brazilian Space Program have asbestos their composition since 70´s; however, they are hazardous human health. In this context, a mixture of Expanded Perlite (PExp) Cork Powder (CP) was investigated replacement...
Thermal protection systems (TPS) are components designed to protect the internal and external areas of a rocket motor from high temperatures. There has been studies in Brazil resin-based polybutadiene hydroxylated (HTPB) loaded with asbestos since 1970s. Nevertheless, banned several countries because it is severely harmful human health. In this context, development free flexible thermal (FTP) extremely important. This study evaluates use Expanded Perlite (PExp) as an substitute. Lower...
