Description
Technical Field
The utility model relates to a setting-out board for polymer sheet tensile test sample.
Background
In the tensile test of the polymer sheet, a cutting knife is generally used to cut a plurality of test pieces 1, which are narrow in the middle, wide at two ends, and the narrow section 11 and the wide section 12 are transited by a first arc section 13 and a second arc section 14 which are tangent, on a polymer sheet sample, wherein the test pieces 1 are bilaterally symmetrical at the middle point and have the shape shown in fig. 1. Then, a ruler or other tool is taken out and a color pen is used to mark a midpoint on the sample, and a connecting line 15 is marked according to the midpoint, thereby obtaining the length L1And connecting line 16, thereby obtaining length L2And obtaining the original gauge length of the sample for the polymer sheet tensile test.
During the actual sample line drawing operation, because the sample size is small, the precision of a measuring tool is not high, deviation is easy to generate in the marking process of the sample line drawing, the precision of original data of a polymer sheet tensile test is reduced, and the effectiveness of a final tensile test result is influenced; and the operation of drawing lines on the sample by adopting tools such as a ruler and the like is long in time consumption and low in efficiency.
