  • Method for fabricating high-temperature tensile test specimens
    Patent number: 5078843
    Abstract: A carbon composite tensile test specimen for high temperature testing and a method of fabricating the same are disclosed. A plurality of holes are drilled in first and second end sections of the specimen and then the end sections are electroplated with nickel. The nickel plating of the end sections prevents breakage of the ends in the jaws of a tensile testing apparatus. For high-temperature testing, a standard-sized specimen may be used with the jaws in the hot zone.
