Membrane Systems
Published in Agis F. Kydonieus, Controlled Release Technologies: Methods, Theory, and Applications, 2019
For several years, Dow Corning Corporation was the only source of silicone polymers. As a result, much of the work reported in the literature refers to the tradename Silastic® silicone rubber and to specific medical-grade cured tubing, sheet, or compounded fluid suitable for curing (cross-linking or vulcanization). Typically, the fluids consist of hydroxy-terminated dimethylsiloxane polymer and a cross-linking agent that can be cured by addition of a catalyst. Cured membranes frequently contain 20 to 30% by weight of an inorganic filler. The filler is usually a reinforcing silica in those formulations that are cured with peroxide or trimethylacetoxysilane and water vapor. However, nonreinforcing diatomaceous earth is the customary filler in the fluids that are cured at room temperature in the presence of stannous octanoate.
Mitigating fuel tank syndrome pelvic injuries – is there potential for rider worn protectors?

The pelvis surrogate consisted of the THOR ATD lumbar spine, pelvis and upper leg components with the original soft tissue removed. This was necessary to allow the pelvis and upper legs of the ATD to be separated to achieve more realistic articulation of these components during the fuel tank during impact. New soft tissue components achieving separation of the pelvis and upper legs were molded from a silicone rubber (Silastic 3481) previously used to replicate the impact response of human thigh tissue (Hrysomallis 2009). Two triaxial accelerometer arrays (Endevco 7264 C-2000) were mounted 4 cm apart on a steel plate rigidly fixed to the posterior lumbar spine of the pelvis surrogate. Two high-speed cameras (Phantom, Vison Research, Wayne, NJ) captured a lateral and overhead view of the impact at 1000 frames per second.
