• Description:
  Future CNT thread sensor work at Nanoworld Laboratories entails several key areas of investigation to prove sensor feasibility for a composite SHM sensor. These key areas of investigation are listed below with descriptive significance. 1. Embedded sensor performance: Although CNT thread appears to perform well outside the composite material, it must have similar if not improved sensor performance once embedded into the material. This will be similar to earlier concept work presented in Section 24.2. 2. Sensor invasiveness: It is suspected that the CNT thread sensor will be minimally invasive to the composite material due to its small size. However, this hypothesis will be tested by examining composite breaking strength, stiffness, elongation, and fatigue strength. 3. Failure mode identification: Composite materials will be fabricated with voids and cracks. Then, the composite material will be excited with broadband excitation to identify these impregnated damage modes with the strain response of the thread. Additionally, impact testing will be done on the composite material to (1) identify the impact through the strain response and (2) potentially assess the damage through CNT thread breakage strain response.
