Problems solved by technology

[0002] Carbon fiber has the advantages of high temperature resistance, small heat storage, excellent heat insulation performance, and high thermal strength. In recent years, carbon fiber has developed rapidly as a high-temperature heat insulation material. And the manufacturing method is very restrictive, so the production efficiency is relatively low. At the same time, due to the influence of the relatively strict production process in the production process, the performance of the carbon fiber itself is damaged, and the comprehensive performance of the product such as heat insulation performance and service life is produced. are not ideal, so this paper proposes a multifunctional composite carbon fiber inner liner and its preparation method

preparation example Construction

[0026] The technical scheme of the present invention is as follows: a preparation method of a multifunctional composite carbon fiber inner liner; the preparation method includes the following steps:

[0027] S1: Preparation of materials: specifically, carbon fibers, polyester fibers, polyurethane fibers, and phenolic fibers are cut into suitable lengths, and the lengths are preferably between 50-150mm.

[0028] Wherein, the diameters of the carbon fibers, polyester fibers, polyurethane fibers and phenolic fibers are between 3-5 μm, and the thinner carbon fibers can ensure that the various fibers themselves will not be broken by the pressure during the subsequent pressurization process. The squashed situation.

[0029] S2: Mixing materials: Specifically, the carbon fiber, polyester fiber, polyurethane fiber and phenolic resin treated by S1 are initially mixed in a certain proportion, and the preferred ratio is (8-10): (4-5): (4- 5): 1.

[0030] The composite carbon fiber inne...

Abstract

The invention discloses a multifunctional composite carbon fiber inner liner and a preparation method thereof.The preparation method comprises the steps that firstly, carbon fibers, polyester fibers, polyurethane fibers and phenolic fibers are cut into proper lengths and mixed, the mixed fibers obtained after mixing are sequentially carded and loosened and then laid flat to form a mixed fiber layer, and under the vibration effect of a vibration meter, the mixed fiber layer is subjected to heat preservation and heat preservation; hot melt adhesive powder is evenly added into the mixed fiber layer, the mixed fiber doped with the hot melt adhesive powder is put into a hot press to be heated, pressurized and shaped, finally, cooling and discharging are conducted, and the multifunctional composite carbon fiber inner liner is obtained finally. Wherein polyester fibers in the mixed fibers can also be a mixture of common polyester fibers and low-melting-point polyester composite fibers, hot melt adhesive powder in the mixed fibers is melted and adhered through the hot pressing effect of a hot press, or fusion is carried out through the combined effect of the low-melting-point polyester composite fibers and the hot melt adhesive powder, and the mixed fibers are formed. The production process and the like of the composite carbon fiber inner liner are simplified and can be completed without complex conditions, and meanwhile, the excellent performance among various fibers is reserved.
