Fiber snubbing clamp using magnetic gripping action

摘要

A device, assembly and method for clamping single fibers that utilizes snubbing surfaces simultaneously with magnetic gripping action are described. The device can be fabricated at miniature sizes with very low mass and volume, which are desirable requirements for testing of small fibers in highly sensitive force-transducing load frames. Advantageously, the combined use of snubbing surfaces and magnetic gripping greatly reduces the probability of slippage or fiber failure at the grip during testing.

主权项

1. A method for determining a mechanical property of a fiber or a multifiber yarn, the method comprising the steps of:
providing a first specimen holder that comprises a portion that comprises a ferromagnetic material or other magnetizable material, attaching a first portion of a fiber or a multifiber yarn to the first specimen holder via a first magnet, providing a second specimen holder that comprises a portion that comprises a ferromagnetic material or other magnetizable material, attaching a second portion of the fiber or the multifiber yarn to the second specimen holder via a second magnet, and displacing the first specimen holder relative to the second specimen holder.
