A mesoscopic distinct element method will allow for simulations of massive fibrous ensembles not only through parallel computing but also through efficient coarse graining of the atomistic scale interactions. This development will accelerate progress by providing the ability to guide experimental design through simulations.
","description":"There is a sustained effort to develop super-lightweight composites by using polymer impregnation of carbon nanotube (CNT) sheets. This promising area is still in its early stages and significant progress is required before CNT-based composites can be used in load bearing aerospace structures. Researchers from the University of Minnesota, Rensselaer Polytechnic Institute, and Skolkovo Institute of Science and Technology in Moscow will develop a broad scope multiscale modeling methodology able to simulate the mechanics of these materials. A mesoscopic distinct element method will allow for simulations of massive fibrous ensembles not only through parallel computing but also through efficient coarse graining of the atomistic scale interactions. This development will accelerate progress by providing the ability to guide experimental design through simulations.

These sheets can contain both randomly-oriented cylindrical CNTs and aligned collapsed CNTs. This promising area is still in its early stages and significant progress is required before CNT-based composites can be used in load bearing aerospace structures. Truly novel and ambitious model development efforts were called to enable computational guided development of super-lightweight composites. Responding to this need, our objective is to develop a multiscale simulation method able to address the meso-scale mechanics, and the strain to failure of purified and hybrid (nanoparticle/polymer)/carbon nanotube (CNT) sheets and yarns.
