Influence of Terahertz Waves on Unidirectional Carbon Fibers in CFRP Composite Materials

Processing and electrical characterization of a unidirectional CFRP composite filled with double walled carbon nanotubes

Nanotube Composite Carbon Fibers

The mechanical properties of materials in small rod-shaped form are of considerable technological interest since, due to their shape and size, they can exhibit appreciably greater strength relative to corresponding macroscopic forms. For example, the mechanical strength of silicon carbide whiskers systematically increases with decreasing whisker diameter over the 100 to 1 micron range. This phe...

Comparison of submicron-diameter carbon filaments and conventional carbon fibers as fillers in composite materials

This review provides a comparison of submicron-diameter carbon filaments and conventional carbon fibers as fillers in composite materials. Carbon filaments (0.1 mm diameter, catalytically grown) are superior to conventional carbon fibers (discontinuous) as a filler in providing polymer–matrix and cement–matrix composites for electromagnetic performance, but are inferior to the fibers as a fille...

Influence of Carbon Nanotubes Dispersion on Thermal Properties of Copper-Carbon Nanotubes (CNTs) Composite Materials

In this present work, two methods for dispersing carbon nanotubes into the copper matrix were tested: a Solid Route process where CNTs are simply mixed with the copper powder and a Liquid Route process where CNTs are dispersed in a copper salt solution and then mixed with the metallic copper powder. Powders are sintered by uni-axial hot pressing process under vacuum atmosphere at 650°C and ther...

Carbon Nanotube Enhanced Composite Materials

Non covalent functionalization by π stacking was accomplished by treating multi walled carbon nanotubes (MWNTs) through the use of Kentera, a conjugate rigid rod polymer. The functionalized MWNTs were then introduced into the epoxy resins through a combination of shear and elongation forces. The resulting epoxy resin (containing MWNTs) was then impregnated with carbon fiber under hot-melt condi...
