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...

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...

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...

Tool Geometry Evaluation for Carbon Reinforced Composite Laminates

SUMMARY The use of composite laminates in complex structures has increased significantly. However, there are still some issues when considering their use, mainly related with machining, leading to some difficulties and lack of acceptance. In this work, a methodology to evaluate drill geometry and feed rate based on thrust force and delamination extension is presented. INTRODUCTION For the past ...
