在这项研究中，进行了实验研究与纯有机硅的五个不同等级和不同等级的有机硅以1：1的体积分数的混合物的皮肤一样的软材料的机器人应用的发展。通过压缩模塑制备样品，并根据ASTM D412标准以250 mm/min的十字头速度对哑铃形试样进行拉伸测试。从实验中观察到，与Luperox 101交联的10级硅酮产生2.189 MPa的拉伸强度，其更接近于前臂中的人皮肤。实验还表明，共混物的拉伸强度低于同等级的纯有机硅。还对样品进行了傅里叶变换红外光谱（FTIR）和扫描电子显微镜（SEM）研究，以了解化合物的分散情况和开发的软材料中的机械损伤。最后，对Mooney-Rivlin、Ogden和Yeoh非线性材料模型进行了数值模拟，计算了10级有机硅的非线性材料常数并制成表格。所开发的软材料将用于未来的机器人软操作。
In this research, an experimental investigation is carried out with pure silicone of five different grades and blended mixture of different grades of silicone at 1:1 volume fraction for the development of a skin-like soft material for robotic applications. The samples are prepared by compression molding and tensile testing was performed on dumb-bell shaped specimens as per ASTM D412 standard at crosshead speed of 250 mm/minute It is observed from the experiments that silicone grade 10 crosslinked with Luperox 101 yielded the tensile strength of 2.189 MPa which is closer to the human skin in forearm. It is also derived from the experiments that blended mixtures 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 and mechanical damages in the developed soft material. Finally, the numerical simulation for Mooney-Rivlin, Ogden and Yeoh non-linear material modes are carried out and non-linear material constants of Silicone grade 10 are computed and tabulated. The developed soft material will be used in robotics for soft manipulation in future.
