abstract
An effective material property estimation is performed that investigates the effect of the nanoparticle/matrix resin interphase thickness and properties on the microscale composite response. The focus of this estimation is on vapor-grown carbon nanofibers (VGCNFs) in a vinyl ester thermoset resin matrix, using classical micromechanics techniques (Mori-Tanaka and Self-Consistant methods) and NASA's special-purpose composite failure analysis code, MAC/GMC which is based on the Generalized Method of Cells (GMC). The predicted properties are compared to those obtained from mechanical testing. 2010 by the American Institute of Aeronautics and Astronautics, Inc.
