Abstract

Purpose - This paper presents an experimental study of the influence of variables such as strain rate, the number of fabric plies, the type of fabric, the kinds of fibre and the shape of indenter on the indentation of fabric under differently shaped pinch gripper. Design/methodology/approach - This experimental study will be approached from three different angles. It will look into an indenter pressing a sample with a much larger size, which is important in practice in the world of grasping by a pinch gripper. It will research a flat indenter, but also an indenter with a curved surface and will investigate fabric compression particularly with regard to the differences between single-layer and multi-layer stacks. Findings - The type of fabric architecture and the kind of fibre have been proven to be important for the indentation. Even more important is the indenter geometry. Evidence collected to date suggests that the grasping action is more sensitive to indenter geometry. This leads to three possible approaches: Close regulation of the materials and processes, handling processes to change in the material properties, and thirdly, intelligent systems which can learn from and adapt to each situation. Research limitations/implications - This study suggests that a picking up operation should change in the material properties, that is, the operation should be controlled by using fabric characteristics as the control information in an intelligent environment. Originality/value - Previous work on compression has been concentrated on an indenter with a size identical to a specimen, this study will look into an indenter pressing a sample with a much larger size. On compression, previous work has focused on single-layer fabric compression by a flat indenter, but this research will not only research a flat indenter and single layers, but also an indenter with a curved surface, and multi-layer stacks. © Emerald Group Publishing Limited.
