Preparation and Performance Study of Warp-knitted Spacer Fabric Based Silica Gel Filled Flexible Manipulator
A kind of flexible buffering material is prepared by using warp knitted spacer fabric as the filling matrix and room temperature vulcanized silicone rubber as the filling agent,and is then applied to the gripper of the manipulator to grasp the fragile material.The filling rates of the silicone rubber are 30%,50%,70%and 100%,respectively.The compressive and impact properties of flexible composites with different filling rates are investigated.The results show that the filling of silicone rubber can improve the load-bearing capacity and slow elastic properties of warp knitted spacer fabrics.The larger the filling rate,the higher the load-bearing capacity and slow elastic properties of flexible buffering materials.Therefore,the filling of silicone rubber improves the slow compressing and slow elastic properties.The 3D printing manipulator mold is adopted,and the filling rate of the silicone rubber is 100%,the prepared flexible composite mechanical gripper both ensures the necessary rigidity,and has reasonable elasticity,which can meet the requirements of handling,clamping and moving of fragile,soft and precious objects.
