Abstract

The invention discloses an aramid tying belt for aerospace and a preparation method thereof. The preparation method includes the steps of (1) warp preparation: grafting polar oxygen-containing groups on the surfaces of meta-aramid fibers to obtain modified meta-aramid fibers, and performing cotton opening, cotton carding, drawing, roving, spinning and shaping on the obtained modified meta-aramid fibers in sequence to obtain warps; (2) weft preparation: blending para-aramid fibers and carbon fibers, and sequentially carrying out cotton opening, cotton carding, drawing, roving, spinning and shaping processes to obtain wefts; and (3) respectively stranding and shaping the obtained warps and wefts, weaving and shaping, and carrying out after-treatment to obtain the aramid tying belt for aerospace. The aramid tying belt for aerospace has excellent flame retardancy and better mechanical properties, and can better adapt to the use requirements in severe environments.

Description

technical field [0001] The invention relates to the field of aramid lace materials, in particular to an aramid lace for aerospace and a preparation method thereof. Background technique [0002] Aramid is a high-temperature-resistant, high-strength, high-modulus fiber with good electrical insulation and chemical stability. Therefore, with the continuous advancement of technology, it is also used in more and more fields. [0003] For example, there is a precedent for using aramid fiber to make parachutes in the prior art. It can adapt to harsh environments, and its quality is reduced by 50% compared with ordinary materials. Broad prospects. [0004] With the continuous increase of its use in aerospace, higher requirements are put forward for its mechanical properties and physical and chemical properties. Contents of the invention [0005] In view of the above-mentioned prior art, the purpose of the present invention is to overcome the problem that the performance of the ar...
