摘要
A model is developed for the elastic moduli of fiber networks composed of elongated particles characterized by aspect ratio polydispersity. The present treatment of elastic fiber networks is integrated with an effective medium model for heterogeneous materials and with percolation theory to provide a framework for describing fiber-reinforced nanocomposites. Model calculations are presented for the dependences of composite moduli on particle aspect ratio, volume fraction, and polydispersity index. (c) 2007 American Institute of Physics.
