Testing of silicone and composite materials under conditions of extreme deformation

Samples of silicone and composite material are studied in various compression modes up to the limiting permissible deformation levels. In the first series of tests, changes in the elastoplastic properties during deformation of a silicone sample without fillers are studied. In the second series of tests, changes in the elastic-plastic properties of a soft composite sample with special fillers are researched. Depending on the various magnitude of deformation, changes in the elastic modules of the tested materials are defined and analyzed. Based on the constructed characteristics, the ranges of the linear and non-linear regions of the compared materials are developed. Changes in the shape under various compression modes and the destruction of the silicone sample at the limiting permissible deformation level are shown. Changes in the shape of a composite sample with magnetic particles are shown under various compression modes. The unique property of the studied material to self-healing after repeat tests for maximum load limits has been established.
