Abstract

Improved, high-strength micro-thermocouples (10) are provided, which include first and second microwires (12, 14) each preferably in the form of an elongated metallic core (18, 22), with an outer glass coating (20, 24); at least one of the microwires (12, 14) is an amorphous microwire (12), and in preferred forms the other microwire is a crystalline microwire (14). The thermocouple junction (16) is formed by stripping the distal ends of the microwires (12, 14) to provide stripped ends (18a, 22a). The stripped crystalline microwire end (22a) is wrapped about the stripped amorphous microwire end (18a) to form a series of abutting convolutions (30). The micro-thermocouples (10) find particular utility in the fabrication and repair of carbon fiber composite materials, such as airplane components.
