Abstract: A winch rigging link has a body defining a cable retainer and a soft shackle retainer at opposite ends. The body has a length, a width less than the length, and a depth less than the width. Furthermore, the body defines opposing faces bounded by the length and width and spaced apart by the depth. The soft shackle retainer comprises a channel running widthwise across the soft shackle retainer an in between the faces. The channel defines a bearing surface having curvature in a lengthwise and widthwise plane. The cable retainer may be permanently attached to a winch cable and the soft shackle retainer attached to a soft shackle or the like when required for winch rigging. The configuration of the link maximises the bend radius of the soft shackle or the like retained by the soft shackle retainer, despite the relatively narrow profile of the body thereof.

Then, a matrix is formed by chemical methylsilane vapor deposition in the reactor. A protective outer monolithic layer is formed from crystals of beta phase stoichiometric silicon carbide over the central composite layer by chemical methylsilane vapor deposition in a CVD reactor. And then the carbon substrate is removed from the fabricated semi-finished product.
