Abstract:

The primary goal of this project was the development of new techniques for toughening elastomeric materials. The first approach taken was the in-situ precipitation of reinforcing filler particles into the elastomers. Preliminary studies focused on the elastomer polydimethylsiloxane PDMS because of the large number of related studies already carried out on this material. Promising techniques were then extended to other elastomers, such as the polyisobutylene. The second approach was the alignment of ferrite-type filler particles to improve reinforcement, at least in chosen directions. This was done during the curing process and utilized a magnetic field of variable strength. Reinforcement Elastomers Fillers Magnetic particles Ultimate properties Toughness.
