摘要
This paper studied the property of adhesive/C-C composites joints in humidity aging with infrared spectrum (IR) energy dispersive X-ray spectroscopy (EDX) scanning electron microscopy (SEM) and shear strength. The decline ratio of shear strength of adhesive/C-C composites joints treated by silane coupling agent were lowest than that treated by sand paper burnish or by chemical oxidation in humidity aging. And shear strength tests also proved time-temperature equivalence between temperature and humidity aging time. SEM of adhesive/C-C composites joints showed that there were no marked changes of the interface and surface of adhesive/C-C composites joints in humidity aging. The changes of IR of the adhesive and EDX of adhesive/C-C composites joints indicated that water penetrative speed on the surface of C-C composites was faster than that on the surface of the adhesive, and water penetrative speed on the surface of the adhesive and C-C composites during humidity aging depended on temperature and humidity aging time.
