- Step-1: The different types of fillers were mixed with RTV-SR through solution mixing. Their concentration was reported in Table 1. The rubber–filler mixing lasted approximately 10 min at which a homogenous phase was achieved in the composite.
- Step-2: Then, 2 phr of curing agent was added and the final composite was mixed again for 1 min before pouring into molds. These molds were then pressed mechanically and kept for 24 h at room temperature for curing.
- Step-3: The samples were finally taken out from the molds and kept into deep freezing (< 0 °C) to inhibit over-curing. It was found that the composites are over-cured if kept at room temperature for more time because of the promotion of additional reactions in the presence of room temperature and moisture.
- Step-4: Finally, the samples were taken out 24 h prior to testing for different reinforcing properties and applications. These applications were energy harvesting in compressive mode and mimicking the electromechanical behavior of samples and biomechanical behavior with tip-toe or heel.
