Buckling Analysis of Spherical Composite Panels Reinforced by Carbon Nanotube

In this study, the buckling behavior of moderately thick Carbon Nano-Tube (CNT)-reinforced spherical composite panels subjected to both uniaxial and biaxial loads is examined. The uniform and various kinds of functionally graded distributions of the CNT are considered. The mechanical properties of the nanocomposite panels are estimated using the modified rule of mixture. Based on the first-orde...

3-D Extraction of Fibres from Microtomographic Images of Fibre-Reinforced Composite Materials

Mechanical properties of molded components made from fibrereinforced composite materials locally depend of the orientation of the fibres. The evaluation of the properties is done by sampling the component at known positions. The samples (of size of 1 mm) are scanned in a tomograph which yields 3-D images. We are interested in extracting the individual fibres, to analyze their length and local o...

Carbon Nanofiber Reinforced Carbon/Polymer Composite

Conventional carbon fiber reinforced phenolic resins are widely used to prepare carbon/carbon composites due to their high carbon yield. Property enhancement of carbon fabric/phenolic composites is possible through carbon nanomaterial dispersion in the matrix. The effect of carbon nanofiber dispersion in phenolic resins/carbon fabric composites was investigated. The dispersion efficiency in dif...

Design of Particulate-Reinforced Composite Materials

A microstructure-based model is developed to study the effective anisotropic properties (magnetic, dielectric or thermal) of two-phase particle-filled composites. The Green's function technique and the effective field method are used to theoretically derive the homogenized (averaged) properties for a representative volume element containing isolated inclusion and infinite, chain-structured part...
