FIELD: fiber assessment.
SUBSTANCE: invention is intended to assess the heterogeneity of the discontinuous characteristics of the bast fiber. The substance of the invention lies in the fact that a set of samples of a certain length and mass is prepared, tested by means of a uniaxial rupture, the breaking force and the inhomogeneity parameter are determined, while as a result of the test for each sample, in addition to the breaking force, the work of the break and the value of the ratio of the work of the break to the breaking force are determined, and the inhomogeneity of the fiber is estimated in in the form of the product of the coefficient of variation of the breaking force for a set of strands and the average value of the ratio of the breaking work to the breaking force.
EFFECT: increasing the information content of assessing the heterogeneity of the discontinuous characteristics of bast fibers.
