Simulation and modeling of three-dimensional percolating structures: Case of a latex matrix reinforced by a network of cellulose fibers

摘要: Abstract The composite presented here, which is made of cellulose whiskers embedded into a latex matrix, shows quite surprising elastic properties due to the fact that continuous skeleton hard formed with some tight interactions. work classical homogenization techniques are not applicable in particular because those do make any difference whether or interactions considered. percolation problem investigated by means numerical simulations quantify threshold and mechanical obtained Percolation Theory simple Voigt model. Finally, description proposed, using Cosserat Continua, where material's behavior exhibits length scale. All parameters associated this determined Finite Element simulations. An attempt understand physical meaning
