[0050] The length of the second C-shaped bottom plate 43 in the Y direction is greater than the length of the first C-shaped bottom plate 33 in the Y direction, and the length of the Y-axis movable guide rail 41 is also longer than the length of the X-direction movable platform 3 in the Y direction, so that the Y-direction fixed slider 42 can slide left and right on the Y-axis movable guide rail 41.

[0057] Step 1: Cut the test sample (instrument panel airbag frame 5) according to the mold characteristics of the product stretching tool 2, and cut through the four sides of the test sample to facilitate stretching.

[0058] Step 2: After the test sample is installed on the product stretching fixture 2, the test sample is matched with the fetal membrane surface and the sample surface in the front, back, left and right directions to prevent movement.

[0059] Step 3: After fixing the four sides of the test sample, connect the test sample to the tensile machine with a connecting lock ring, and the experiment begins;

[0060] Step 4: During the stretching process of the tensile machine, the X-axis fixed slider 32 slides along the X-axis movable guide rail 31, and the Y-axis fixed slider 42 slides along the Y-axis movable guide rail 41, and is automatically aligned to keep the experimental sample perpendicular to the tensile force output by the tensile machine;

[0061] Step 5: The sensor of the tensile testing machine obtains the tensile strength of the edge;

[0062] Step 6: Stretch the remaining three edges in turn to obtain the tensile strength of each edge, and the test is completed.
