Effect of Pressure and Temperature on Dielectric Response of Silicone Composites

Use of lightweight polymeric materials in aircraft insulation, leads to reduction in overall weight as well as aids in improved performance. However, for successful implementation of these polymeric materials, specific studies in terms of, improvement in processability, performance evaluation due to variation in pressure and temperature, are required. In this study, silicone rubber filled with silica of different particle size; micrometer and nanometer are considered, and the fillers are loaded to the maximum possible weight percent. An in-house built electrostatic disperser is employed to homogeneously disperse the fillers within the silicone matrix. The thermal and dielectric properties are compared and analyzed with changes in temperature and pressure.
