Pan Nanofibers And Nanofiber Reinforced Composites, Cheng Ren Aug 2013

Pan Nanofibers And Nanofiber Reinforced Composites, Cheng Ren

Mechanical (and Materials) Engineering -- Dissertations, Theses, and Student Research

Nanomaterials play an important role in the development of nanotechnology. They possess unique mechanical, physical, and chemical properties coupled with small size and ultrahigh surface area that can provide critical advantages for applications. Continuous nanofibers attract special interest due to their dual nano-macro nature and ability to bridge scales. Nanofibers are being considered for a broad range of applications spanning advanced filters, separation membranes, ultrasensitive sensors, micro/nano actuators, nanoprobes, tissue engineering scaffolds, protective and smart closing, and multifunctional composites. Most of these applications require certain mechanical properties and robustness. However, the literature on the mechanical behavior of nanofibers and ...


Preparation And Characterization Of Whey Protein Isolate Films Reinforced With Porous Silica Coated Titania Nanoparticles, Dattatreya M. Kadam, Mahendra Thunga, Sheng Wang, Michael R. Kessler, David A. Grewell, Buddhi P. Lamsal, Chenxu Yu Jul 2013

Preparation And Characterization Of Whey Protein Isolate Films Reinforced With Porous Silica Coated Titania Nanoparticles, Dattatreya M. Kadam, Mahendra Thunga, Sheng Wang, Michael R. Kessler, David A. Grewell, Buddhi P. Lamsal, Chenxu Yu

Agricultural and Biosystems Engineering Publications

Whey protein isolate (WPI) films embedded with TiO2@@SiO2 (porous silica (SiO2) coated titania (TiO2)) nanoparticles for improved mechanical properties were prepared by solution casting. A WPI solution of 1.5 wt% TiO2@@SiO2 nanoparticles was subjected to sonication at amplitudes of 0, 16, 80 and 160 μm prior to casting in order to improve the film forming properties of protein and to obtain a uniform distribution of nanoparticles in the WPI films. The physical and mechanical properties of the films were determined by dynamic mechanical analysis (DMA), thermogravimetric analysis (TGA), and tensile testing. Water vapor permeability (WVP) measurements revealed ...


Enhanced Polymer Nanocomposites For Condition Assessment Of Wind Turbine Blades, Husaam S. Saleem, M. Thunga, M. Kollosche, Michael R. Kessler, Simon Laflamme Apr 2013

Enhanced Polymer Nanocomposites For Condition Assessment Of Wind Turbine Blades, Husaam S. Saleem, M. Thunga, M. Kollosche, Michael R. Kessler, Simon Laflamme

Civil, Construction and Environmental Engineering Conference Presentations and Proceedings

Damages in composite components of wind turbine blades and large-scale structures can lead to increase in maintenance and repair costs, inoperability, and structural failure. The vast majority of condition assessment of composite structures is conducted by visual inspection and non-destructive evaluation (NDE) techniques. NDE techniques are temporally limited, and may be further impeded by the anisotropy of the composite materials, conductivity of the fibers, and the insulating properties of the matrix. In previous work, the authors have proposed a novel soft elastomeric capacitor (SEC) sensor for monitoring of large surfaces, applicable to composite materials. This soft capacitor is fabricated using ...
