Abstract

In order to improve thermal and electrical properties of insulating materials, they are modified with micro- or nanoscopic fillers. This fillers have however also an influence on the mechanical properties of the material [1]-[2]. Therefore, in this contribution the mechanical tensile strength and the elongation at break of thermally aged silicone elastomers were investigated. Silicone samples with different amounts of microscopic graphite filler were prepared. Also layered samples are used with one layer made of pure silicone without fillers and the other made of the same base silicone, mixed with a specific amount of microscopic graphite filler. It is expected the individual layers to have different tensile strengths. The samples were prepared and tested according to the standard DIN 53504:2017 03 (ISO 37). The investigation shows that the filler has an influence on the tensile properties of aged and unaged silicone.
