In molecular dynamics simulation, the cross-linked epoxy resin model can well simulate performance of in actual use. We have established a and composite aluminum at level. Based on ReaxFF, reaction simulation pyrolysis aging was carried out by Lammps. The aged is decomposed into H 2 , CO, O, CO CH 4 O. Tensile system out, stress-strain curve obtained. Compared with non-aging, maximum stress red...
