Investigators from Naval Postgraduate School Zero in on Materials Research (Fabrication of a Low Density Carbon Fiber Foam and Its Characterization as a Strain Gauge)
By a News Reporter-Staff News Editor at Journal of Technology -- Data detailed on Materials Research have been presented. According to news reporting originating from Monterey, California, by VerticalNews correspondents, research stated, "Samples of carbon nano-fiber foam (CFF), essentially a 3D solid mat of intertwined nanofibers of pure carbon, were grown using the Constrained Formation of Fibrous Nanostructures (CoFFiN) process in a steel mold at 550 degrees C from a palladium particle catalysts exposed to fuel rich mixtures of ethylene and oxygen. The resulting material was studied using Scanning Electron Microscopy (SEM), Energy Dispersive Spectroscopy (EDX), Surface area analysis (BET), and Thermogravimetric Analysis (TGA)."
Our news editors obtained a quote from the research from Naval Postgraduate School, "Transient and dynamic mechanical tests clearly demonstrated that the material is viscoelastic. Concomitant mechanical and electrical testing of samples revealed the material to have electrical properties appropriate for application as the sensing element of a strain gauge. The sample resistance versus strain values stabilize after a few compression cycles to show a perfectly linear relationship. Study of microstructure, mechanical and electrical properties of the low density samples confirm the uniqueness of the material: It is formed entirely of independent fibers of diverse diameters that interlock forming a tridimensional body that can be grown into different shapes and sizes at moderate temperatures."
According to the news editors, the research concluded: "It regains its shape after loads are removed, is light weight, presents viscoelastic behavior, thermal stability up to 550 degrees C, hydrophobicity, and is electrically conductive."
