Investigating Mechanical Behaviors of Silica Nanoparticle Reinforced Composites

This paper presents a review of current research, both theoretical predictions and experimental measurements, on the mechanical properties of carbon nanotubes (CNTs). The emphasis has been given to the tensile strength and Young’s modulus. Deformabilities including buckling, bending, and twisting are also examined. The predicted and measured values of mechanical behaviors of CNTs are compared and an analysis on the variation of the values is made. The challenges facing the research of mechanical properties of CNTs are stated. CNT reinforced composites are involved as well in the paper. A thorough understanding of the properties of CNTs helps exploring full applications of this unique group of materials.

A series of binary oxides and SiC whisker reinforced composites both having a matrix composed of an α-(Al, R)2O3 solid solution (R: rare earth) have been studied by analytical electron microscopy (AEM). The mechanical properties of the composites as well as crystal structure, composition, and defects of both second phases and the matrix were investigated. The formation of various second phases, e.g. garnet, β-Alumina, or perovskite structures in the binary Al2O3-R2O3 and the ternary Al2O3-R2O3-SiC(w) systems are discussed.Sections of the materials having thicknesses of 100 μm - 300 μm were first diamond core drilled. The discs were then polished and dimpled. The final step was ion milling with Ar+ until breakthrough occurred. Samples prepared in this manner were then analyzed using the Philips EM400T AEM. The low-Z energy dispersive X-ray spectroscopy (EDXS) data were obtained and correlated with convergent beam electron diffraction (CBED) patterns to identify phase compositions and structures. The following EDXS parameters were maintained in the analyzed areas: accelerating voltage of 120 keV, sample tilt of 12° and 20% dead time.
