High-Strength Hollow Glass Microsphere/Epoxy Resin Composite Insulation Materials for Deep In-Situ Condition Preserved Coring

Figure 8

DTG curves of the HGM/EP composite insulation materials. The peak thermal decomposition temperatures for the HGM/EP composite insulation materials with HGM volume fractions of 10 vol%, 20 vol%, 30 vol%, 40 vol%, 50 vol%, and 60 vol% were 368.0°C, 369.8°C, 371.9°C, 371.4°C, 369.7°C, and 371.1°C, respectively.
