|Title:||Development Of Nanocomposite Material For Rapid Manufacturing: Application In Microreactor Technology|
|Abstract:||Many applications in the field of rapid manufacturing require materials with specific characteristics in terms of weight and mechanical resistance which are difficult to obtain using simple polymeric, ceramic and metallic materials. In this work, a nanocomposite material was development to fabricate 3D structures via thermolithographic process using CO 2 laser. Nano silica particles were added in epoxy resin matrix in order to produce final devices with specified properties. An experimental analysis, using Differential Scanning Calorimeter (DSC), was used to determine the kinetic parameters (fractional conversion, reaction rate, heat of reaction, and activation energy). The kinetic curing was studied using a computational modeling to describe of the curing process, presenting a good agreement with experimental. With nano silica particles dispersed in the epoxy matrix, the study on the material behavior was analyzed by a Scanning Electron Microscopy (SEM), and three dimensional structures in the thermolithography process were fabricated. © 2008 Taylor & Francis Group.|
