Designing damage-tolerate nanocomposite materials will help secure satellites, nuclear reactors and aircraft.
Analyzing the capabilities of a lightweight, strong material could lead to a replacement for aluminum steel for power plants and spacecraft.
Developing nanocomposite strain sensors could extend building life and prevent catastrophic structural failures.
The project research goal is to develop design guidelines for damage tolerant structures for circular hollow sections of seamless carbon fiber reinforced polymer (CFRP) matrix composites. The researcher has tested how to conduct the hydrostatic testing and identified what factors must be overcome before testing. The damage characterization of internal pressurization can be used by
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
The scope this FURI research project is to address the time intensive problem of fabricating buckypaper by using fused deposition modeling(FDM). Buckypaper has already shown proven benefits to society due to is unique properties that allow real time strain sensing. Findings have shown that 3D printer thermoplastic filament can be dosed with large amounts of
The research goal is to characterize the material properties of shape memory polymers (SMPs) as they are repeatedly broken down and recycled. SMPs have medical and military applications, and can be rapidly prototyped using 3D printing, which results in relatively large quantities of thermoplastic waste. If this research can prove that recycled SMPs sufficiently retain
The research focuses on nanocomposite sensors made by inserting a carbon nanotube membrane (buckypaper) between glass fiber-reinforced polymer (GFRP) substrates. The goal is to enhance the sensor’s fatigue response by inducing a residual compressive pre-stress state on the CNT membrane while inducing a tensile pre-stress on the glass fiber substrates. Benefits of this research will
