Carbon nanotube sheet for structural health monitoring and thermal conductivity in laminated composites

Abstract: Two limitations of polymeric fiber reinforced composite materials are their susceptibility to damage, and their reduced thermal conductivity compared to metals.This thesis proposes techniques to address these limitations and to make composite materials more multi-functional and reliable like metals.Laminated composites are prone to damage due to impacts which cause localized delamination and microcracking.It is challenging to detect these types of damages because non-destructive inspection takes the structure out of service, inspection is slow and expensive on large structures, and the damage may not be obvious on the outer surface.Left undetected, the damage can propagate due to loading during normal use and lead to reduced performance or failure of a component or the entire structure.In most applications, detection of these internal damages is critical to maintain the performance and structural integrity of components, and to assure the safety of the aircraft or wind turbine.Composites are used because I want to thank my colleague at NanoWorld Michael Paine for guiding and teaching me the fabrication and curing of composite materials, Ng Vianessa and Daniel Chen for giving me insights into the synthesis of Carbon nanotube and Hybrid carbon nanotubes.I want to thank Ronald Hudepohl for helping me at the machine shop to prepare machined components.Devika Chauhan helped me teaching SHM testing and providing SEM images.
