Abstract
In this research, an experimental investigation is carried out with pure silicone of five different grades and blended mixture of differentgrades of silicone at 1:1 volume fraction for the development of a skin-like soft material for robotic applications. The samples areprepared by compression molding and tensile testing was performed on dumb-bell shaped specimens as per ASTM D412 standardat crosshead speed of 250 mm/minute It is observed from the experiments that silicone grade 10 crosslinked with Luperox 101 yieldedthe tensile strength of 2.189 MPa which is closer to the human skin in forearm. It is also derived from the experiments that blendedmixtures revealed the lower tensile strength than pure silicone of the same grade. Fourier Transform Infrared Spectroscopy (FTIR)and Scanning Electron Microscope (SEM) studies were also done on samples to understand the dispersion of the compounds andmechanical damages in the developed soft material. Finally, the numerical simulation for Mooney-Rivlin, Ogden and Yeoh non-linearmaterial modes are carried out and non-linear material constants of Silicone grade 10 are computed and tabulated. The developedsoft material will be used in robotics for soft manipulation in future.
