and their results were also analyzed. The results show that the friction between iron particles and rubber matrix is main source for dynamic damping of MRE. 2 Experimental 2.1 Materials fabrication... on a flat vulcanizer for vulcanizing. The mass continents of MRE sample were that HTV silicone rubber was 17.64%, iron powders was 80%, DOP was 2%, and vulcanized agent was 0.36%. In order to compare......
