Instrumental control system of discontinuous characteristics of flax fiber

For flax fibers testing under tension similar to the conditions that take place during their processing, an instrumental control system with the use of tensile strength tester is proposed. A method for determining the breaking force of the fiber sample at high-speed tension, which consists of controlling the time and angular coordinate of the pendulum of tensile strength tester, is created. This enables to calculate the angular acceleration, and its magnitude - the tensile force at break. An instrument system for monitoring the breaking force of flax fiber, including modules for mechanical testing and calculation of the breaking force is developed.
