STUDY ON IMPACT RESISTANCE OF RUBBER ARAMID FIBER COMPOSITES

Abstract

Abstract: A new structure of rubber aramid fiber composite is presented. The LS-DYNA dynamics software was used to establish a model to simulate the impact resistance properties of rubber aramid fiber composites under low-speed impact loads. In order to measure the impact resistance parameters of this structure, the impact test instrument was used to perform low-speed impact tests. By comparing the simulation results with experimental results, the validity of the simulation method was verified. Based on the verification model, the influence of the geometric parameters of the structure on the impact resistance was further studied. The conclusion shows that the rubber aramid fiber composite has excellent impact resistance. It lays the foundation for the wide application of rubber aramid fiber composite materials in high-tech fields such as helmets and body armor.
