Problems solved by technology

The above hybrid method effectively improves the wave-absorbing performance of the composite material, but it is difficult to match the surface input wave impedance of the wave-absorbing material with the wave impedance of the free space only through the arrangement of glass fibers, and the use of a large number of glass fibers will definitely reduce the Mechanical Properties of Composite Materials

Abstract

The invention discloses a method for preparing a carbon fiber / glass fiber hybrid stealth composite material, specifically: carbon fiber is used as a core yarn, glass fiber is used as a weaving yarn, and two-dimensional weaving technology is used to weave the core yarn and the weaving yarn into carbon fiber / glass fiber Core-spun yarn; then the carbon fiber / glass fiber core-spun yarn is woven into cloth, and finally the cloth and epoxy resin are compounded and cured by resin transfer molding to obtain a carbon fiber / glass fiber hybrid stealth composite material. The present invention uses the carbon fiber / glass fiber core-spun yarn structure to utilize the wave-transmitting properties of glass fibers to allow electromagnetic waves to enter the interior of the core-spun yarn to the greatest extent, and then utilizes the resistance loss of carbon fibers to convert electromagnetic wave energy into heat energy or other forms. energy is dissipated. At the same time, as the core yarn, the carbon fiber is basically in a straight state, so that its mechanical properties can be effectively exerted, so that the fabricated stealth composite material has good mechanical properties.

Description

technical field [0001] The invention belongs to the field of composite materials and relates to a method for preparing a carbon fiber / glass fiber hybrid stealth composite material. Background technique [0002] With the rapid development of microwave electronic technology, various weapon systems in the future battlefield are facing severe threats. As an effective means to improve the survival and penetration capabilities of weapon systems, stealth technology has been highly valued by countries all over the world. Stealth technology refers to the technology that reduces the detectability of the target in a certain microwave detection environment, making it difficult to be found in a certain wavelength range. The stealth capability of the weapon system can be realized through shape design and the use of stealth materials. The shape stealth technology is difficult, high cost, and easy to degrade the structural performance of the target; while the use of stealth material techn...
