Problems solved by technology

[0004] However, the existing thermal drawing process design of high-performance fibers is usually determined after repeated debugging before the production line is started. This is not only time-consuming and laborious, but also has a long debugging cycle, and lacks real-time tracking and detection of the internal structure of the fiber. The quality of the fiber cannot be guaranteed

Abstract

The invention provides a high-performance fiber synchrotron radiation in-situ testing machine. The testing machine comprises a base, a chassis, a drafting hot box, a front drafting mechanism, a back drafting mechanism, a winding mechanism and a translating mechanism, wherein the drafting hot box is used to heat fibre tows, one side of the box body opposite to the heat fibre tows is provided with a working gap; the front and back drafting mechanisms are used to provide drafting force for drafting the heated heat fibre tows; the winding mechanism is used to wind the heat fibre tows after hot stretching; and the translating mechanism is used to move the chassis horizontally and contains a translation motor, a turn-screw and a slideway. The testing machine has reasonable structure and convenient operation and is used commonly with the synchrotron radiation device so as to timely and accurately test the molecular changes of the high-strength and high-modulus polyethylene fibre tows under hot stretching, provide powerful technical support for the hyperploid hot stretching technology of the production of high-performance fiber, shorten debugging period and ensure the quality of fiber products.

Description

technical field [0001] The invention relates to a high-performance fiber synchrotron radiation in-situ detection testing machine. Background technique [0002] High-performance fibers represented by carbon fiber, aramid fiber and high-strength high-modulus polyethylene fiber play a pivotal role in modern warfare, aerospace, sea defense, weaponry and other fields due to their excellent performance; at the same time, they are used in automobiles, ships , rope nets, medical equipment, sports equipment and other fields also have broad application prospects. [0003] The hot drawing process is required in the production process of high-performance fibers. Taking the production of high-strength and high-modulus polyethylene fibers as an example, it dissolves ultra-high molecular weight polyethylene in the first solvent to make a polyethylene solution; the solution is made of Extruded by a screw extruder, then sprayed out through the spinning box, cooled and solidified into jelly ...
