Study The Mechanical Properties of Starch-Silicone Rubber Composites Using in Prosthetic Liners

In this work we study the influence of addition of different percents of the starch to the silicone rubber to determine the right addition for manufacturing high-performance prosthetic liner. The optimum result shows 5 % of starch because this percent gives the highest mechanical properties. As detailed, the presence of filler tended to increase the hardness of the samples whilst reduce the tensile and tear strength. Starch is extremely hydrophilic, this leads to absorbing the accumulated sweat between the liner and stump besides that its used to reduce cost. Thus, it was expected that this would lower the values of the mechanical properties (the tensile strength, tear resistance, elongation, compression and elastic modulus) show decrease as a percent of starch increase
