Study on Thermal Stability Properties of Epoxy Matrix/Fluorine and Silicon Composites

Abstract:

Fluorine and silicon resin has excellent thermal stability properties. The thermal stability properties of polymers modified by fluorine and silicon resin can be improved. In this paper, fluorine and silicon resin has been prepared by (1,3,5-tris(trifluoropropylmethyl)-cyclotrisiloxane and 3-aminopropyltriethoxysilane. The FTIR spectra and the 1H NMR spectrum showed the structure of fluorine silicon resin. The thermo gravimetric traces indicated that fluorine silicon resin had improved the thermal stability properties of epoxy matrix resin significantly. The temperature of decomposition velocity of unmodified epoxy matrix resin and modified epoxy matrix resin began to increase rapidly were 356oC, 375oC respectively. The final weight fraction of unmodified epoxy matrix resin and modified epoxy matrix resin were 4.6%, 6.5% , respectively. The temperature of the maximum rate of degradation were 398oC, 420oC, respectively.
