Problems solved by technology

It is impossible to complete the assembly process by using the previous self-adaptive technology combined with a single elastic material and multiple sets of ultra-fine wires. Therefore, it is necessary to develop a suitable elastic modulus and diameter, high stress stability and rebound rate, and good durability. Elastomers with aging properties

Abstract

The invention provides a self-adaptive fiber used in Z-pinch wire-array loads and a preparing method thereof. The self-adaptive fiber is prepared from aliphatic series oligomer diol with the molecular weight of 500-10000, high-symmetry aromatic diisocyanate and a high-symmetry aromatic diamine compound. According to the preparing method of the self-adaptive fiber, at first, aliphatic series oligomer diol with a certain mole number and high-symmetry aromatic diisocyanate with the mole number being twice that of diol are adopted for carrying out prepolymerization, and high-symmetry aromatic diamine is used for carrying out chain extension so that a spinning solution can be prepared; finally, any one of a solution dry method and a solution wet method is adopted for carrying out spinning, forming and processing. In the self-adaptive fiber, cohesion energy density in a hard chain section is high, binding force of the hard chain section is large, dimensional stability is high, rebound resilience is good, and stress stability is high; according to the self-adaptive fiber, during the whole service period, obvious stress relaxation is avoided, and rebound stress can be kept unchanged for a long term.

Description

Technical field [0001] The invention belongs to the field of Z-pinch wire array loading, and specifically relates to the use of an adaptive fiber for Z-pinch wire array loading. Background technique [0002] In the research of Z-pinch-driven inertial confinement fusion, the wire array is currently the ideal load. It forms plasma under the action of the high current of the pulse power device, and under the action of the Lorentz force, it quickly pinches inward, resulting in high temperature , High-density plasma. The precise control of the initial state of the wire array such as the uniformity of the diameter of the ultrafine wire, the uniform arrangement of the ultrafine wire in the radial and angular directions of the electrode and the straightness of the ultrafine wire is to obtain high symmetry, high function and high energy radiation. The key to the source. [0003] The installation of the wire array in the target chamber of the driving device is carried out under normal pres...
