EFFECT OF ACCELERATED THERMO-OXIDATIVE AGING ON THERMAL PHYSICS PROPERTIES OF GLASS FIBER/PHENOL COMPOSITES

Abstract

Abstract: Accelerated thermo-oxidative aging on glass fiber/phenol composite materials was performed at 130 ℃, and the thermal physical properties were tested, 30 days, 60 days, 90 days, and 120 days before aging test, respectively. IR spectroscopy and SEM were organized before aging and after aging for 120 days. The results show that the linear thermal expansion coefficients and specific heat capacity decrease, and then increase, and decrease again. Thermal conductivity has no change during the whole aging time. Physical aging exists all the time, and chemistry aging arises after 120 days.

Key words: thermo-oxidative aging, thermal physics properties, SEM, IR spectroscopy
