Nano material testing apparatus and method for testing material using the same

A method for testing a material using a nano material testing apparatus including a testing unit including an actuator coupled to an upper portion of a main frame and generating displacement of a nano material specimen and a load cell connected to the actuator, a jig unit configured to be connected to the testing unit and comprising an upper jig that clamps one side of an upper portion of the nano material specimen and a lower jig that is located below the upper jig and clamps one side of a lower portion of the nano material specimen, a stage unit configured to make the lower jig to be moved in a multi-axis direction, a first alignment unit configured to provide an image of a front surface of the nano material specimen and to allow alignment in a direction of the front surface of the nano material specimen to be checked, a second alignment unit configured to provide an image of side surfaces of the nano material specimen and to allow alignment in a direction of the side surfaces of the nano material specimen to be checked, a specimen auxiliary fixing device configured to selectively clamp the other side of the nano material specimen, and a load cell protection device that is selectively connected to the upper jig by moving forward/backward, the method comprising:

• mounting the nano material specimen on the specimen auxiliary fixing device, wherein the mounting is performed by a worker;
• moving the stage unit to move the lower jig to the specimen auxiliary fixing device and then, moving the nano material specimen to the lower jig, mounting the nano material specimen on the lower jig, and moving the stage unit so that the lower jig is moved to be below the upper jig, wherein the moving, the moving, the mounting, and the moving are performed by the worker;
• checking alignment of the nano material specimen using the first alignment unit and the second alignment unit to adjust a position of the nano material specimen, wherein the checking and the adjusting are performed by the worker;
• mounting the nano material specimen on the upper jig in a state in which the load cell protection device is connected to the upper jig, wherein the mounting is performed by the worker;
• separating the load cell protection device from the upper jig and then carrying out a test by moving the actuator, wherein the separating and the carrying out is performed by the worker;
• and
• measuring a change in the nano material specimen using information received from the first alignment unit, the second alignment unit, and the load cell during a test, wherein the measuring is performed by a controller.
