Abstract

The effects of long-term exposure to heat and humidity on polymer matrix composites' interphase properties have not been given enough attention in the literature. The composite samples were exposed to 60°C and 90% humidity for over two years. The advanced Peak Force Tapping (PFT) technique was used to investigate the interphase properties at sub-micron-and nano-scales. So far, the results show enhancement of the interphase thickness from 10 nm in the reference sample to ~ 77 nm in the two-year exposed specimen and reduction in roughness with an increase of exposure time.
