Abstract
It is well known that the mechanical resistance of soft materials such as rubber and elastomer can be
improved by cross-linkages or fillers, which will lead to a construction of entangled structure of polymer
chains’ network. However, the correlation between the amount of cross-linkages or fillers with the
toughness strength of the resultant material has not been clarified. Therefore, in this study, we at first
construct a computational model for the resultant material with molecular dynamics method. Then, a series
of simulations are performed for the resultant materials with different amount of cross-linkages or fillers
under high speed loading condition. Finally, the development of entangled structure of polymer chains’
network is investigated and the effect of such development on the toughness strength of soft materials is
evaluated. The results show that even though the increase of the amount of cross-linkages leads to the
increase of the mechanical resistance, the development of the average radius of gyration of polymer chains
is suppressed. As a result, the relative movement of polymer chains is limited in the soft material with large
amount of cross-linkages and the toughness strength decreases eventually. With regard to the effects of
speed of loading on the development of entangled structure of polymer chain’s network as well as the
toughness strength of soft materials, we will show them in our full paper.
