specific Embodiment approach 1

[0020] Specific embodiment 1: The preparation method of the fiber composite reinforcement strip in this embodiment is carried out according to the following steps:

[0021] 1. Lay the bottom Vectran fiber cloth: Lay the bottom Vectran fiber cloth on the horizontal work surface to ensure that the fiber cloth has no in-plane prestress;

[0022] 2. Brush glue: along the length direction of the bottom Vectran fiber cloth, evenly brush epoxy resin glue on the surface of the bottom Vectran fiber cloth;

[0023] 3. Spread the carbon fiber cloth in the middle layer: spread the carbon fiber cloth flat, and paste it on the top of the bottom Vectran fiber cloth treated in step 2 to obtain two layers of composite fiber cloth;

[0024] 4. Glue brushing: evenly brush epoxy resin glue on the surface of the carbon fiber cloth obtained in step 3 to obtain two layers of composite fiber cloth;

[0025] 5. Spread the upper layer of Vectran fiber cloth: pave the upper layer of Vectran fiber cloth...

specific Embodiment approach 2

[0030] Specific embodiment two: the difference between this embodiment and specific embodiment one is that the special mold described in step six is ​​composed of male mold 1 and female mold 2, male mold 1 is provided with boss 3, and the surface of boss 3 is provided with There are a plurality of protruding marks 4, the female mold 2 is provided with a groove 5, the surface of the groove 5 is provided with a dimple 6 matching the protruding mark 4, and the outer contour line 7 of the cross section of the protruding mark 4 forms a circle arc.

Abstract

The invention provides a preparation method for a fiber composite material reinforcing strip and relates to a preparation method for an inflating extending arm reinforcing strip. By the preparation method, the problems that the elastic reinforcing steel strip in the conventional charging extending arm is magnetized easily and the unit mass is high are solved. The preparation method for the fiber composite material reinforcing strip comprises the following steps of: 1, paving bottom layer Vectran fiber cloth; 2, brushing epoxy resin glue on the surface of the bottom layer Vectran fiber cloth; 3, paving interlayer carbon fiber cloth; 4, brushing epoxy resin glue on the surface of the interlayer carbon fiber cloth; 5, paving upper layer Vectran fiber cloth; 6, placing the three layers of composite fiber cloth into a special die, placing into a constant-temperature chamber, heating and curing; and 7, cutting the cured three layers of composite fiber cloth to obtain the fiber composite material reinforcing strip. The preparation method for the fiber composite material reinforcing strip has a simple process. The reinforcing strip has corrosion resistance, ageing resistance, light weight, high straightness and high tensile strength and bending rigidity, and is not magnetized. The fiber composite material reinforcing strip is applied to the charging extending arm.

Description

technical field [0001] The invention relates to a method for preparing an inflatable stretch arm reinforcement strip. Background technique [0002] The elastic reinforced steel bars in the existing inflatable stretch arm are easily magnetized on the satellite, and the magnetic moment generated after the stretch arm is inflated and deployed can affect the attitude of the satellite, and the elastic reinforced steel bars have high density and high unit mass. In order to solve the problem that the existing steel bars are easily magnetized and realize the lightweight of the structure. Contents of the invention [0003] The invention aims to solve the problems of easy magnetization and high unit mass of the elastic reinforced steel strip in the existing inflatable stretching arm, and provides a preparation method of the reinforced strip made of fiber composite material. [0004] The preparation method of the fiber composite reinforced strip of the present invention is carried o...
