This experiment analyzed the structural capabilities of polymer matrix composite (PMC) samples after many years of exposure to hygrothermal conditioning. This strong, form-adaptive, lightweight material is suitable for use on critical structures including powerplants and spacecrafts, however, the degradation impacts from long-term exposure to heat and humidity is yet unverified. To study that phenomena, aged
Polymer Matrix Composites (PMCs) and nanocomposites have become widely preferred in high application designs, like aircraft, satellites, and other critical components, due to their high strength ratio to their weight. However, one of their drawbacks is delamination. Delamination is a mode failure that causes the material to separate into layers and lose its mechanical toughness.
The primary objective of this study is to understand how the low energy scanning electron microscopy can efficiently be used to characterize the nanoscale interphase domain in polymer matrix composite materials. This study will show how low energy scanning electron microscopy can efficiently be used to characterize effects of durability, including heat and humidity, on

The main objective of this research is to characterize the two fabrication techniques for manufacturing carbon nanotube-based sensors and optimize them for piezo-resistive response. The traditional method of fabrication, vacuum filtration (VF), will be investigated, along with a novel method called surfactant-free (SF). Samples from both methods are prepared by modulating pre-fabrication conditions and their
