Embodiment 1

[0020] Example 1: Making carbon fiber products-skis

[0021] The weight ratio of the core material powder is 50 parts of linear low-density polyethylene, 25 parts of unexpanded medium temperature microspheres, and 25 parts of unexpanded high temperature microspheres to meet the best mechanical requirements when making skis. The skis made with the above ratio have better impact resistance.

[0022] The specific method is to put the above-mentioned mixed core material powder into the cavity 8 of the foaming mold 7, and the core material powder occupies one-half of the volume of the cavity 8 of the foaming mold 7; airtight the foaming mold 7 , Heat to 120°C, and continue the temperature for 10 minutes; after cooling and releasing the pressure, open the foaming mold 7 to obtain the first foaming model 401, which is the semi-finished product of the ski; then, the carbon fiber prepreg 3 is cut into The shape of the first foaming model 401 corresponds to the shape, and sticking it to the...

[0023] Example 2: Making carbon fiber products-boat oars

[0024] The weight ratio of the core material powder is 65 parts of linear low-density polyethylene, 15 parts of unexpanded medium-temperature microspheres, and 20 parts of unexpanded high-temperature microspheres, so as to meet the best mechanical requirements when making boat propellers. The paddle made according to the above ratio has better rigidity.

[0025] The specific method is to put the above-mentioned mixed core material powder into the cavity 8 of the foaming mold 7, and the core material powder occupies one-half of the volume of the cavity 8 of the foaming mold 7; airtight the foaming mold 7 , Heat to 120 ℃, and continue the temperature for 20 minutes; after cooling and releasing the pressure, open the foaming mold 7 to obtain the first foaming model 401, which is the semi-finished product of the oar; then, the carbon fiber prepreg 3 is cut into Describe the shape corresponding to the shape of the first foaming...

Embodiment 3

[0026] Example 3: Making carbon fiber products-UAV tail

[0027] The weight ratio of the core material powder is 30 parts of linear low-density polyethylene, 15 parts of unexpanded medium-temperature microspheres, 15 parts of unexpanded high-temperature microspheres, and 40 parts of expanded high-temperature microspheres. The best mechanical requirements for the UAV tail, the UAV tail made according to the above ratio has better toughness.

[0028] The specific method is to put the above-mentioned mixed core material powder into the cavity 8 of the foaming mold 7, and the core material powder occupies one-half of the volume of the cavity 8 of the foaming mold 7; airtight the foaming mold 7 , Heat to 120 ℃, and continue the temperature for 30 minutes; after cooling and releasing the pressure, open the foaming mold 7 to obtain the first foaming model 401, which is the semi-finished product of the UAV tail; then the carbon fiber prepreg 3 is cut into The shape corresponding to the sh...

Abstract

The invention discloses a preparation method of a carbon fiber product. The preparation method comprises the following steps: uniformly mixing linear low density polyethylene with thermoplastic plastic swellable microspheres packaging hydrocarbon in proportion to form core material powder; adding the mixed core material powder into a mold cavity of a foaming mold; sealing the foaming mold, heating the foaming mold to be 110-130 DEG C, and maintaining the temperature for 10-30 minutes; after carrying out cooling and decompression, opening the foaming mold to obtain a primary foaming model; gluing cut carbon fiber presoaked cloth to the primary foaming model; putting the primary foaming model glued with the carbon fiber presoaked cloth into a mold cavity of a product mold; sealing the product mold, heating the product mold to be 100-180 DEG C, and maintaining the temperature for 30-60 minutes; after carrying out cooling and decompression, opening the product mold, so as to obtain a secondary foaming model, namely the carbon fiber product. The carbon fiber product prepared by virtue of the preparation method is firm in structure, low in density and preparation cost and high in production efficiency, and dead corner is avoided by virtue of internal force.

Description

Technical field [0001] The invention relates to the technical field of carbon fiber composite materials, in particular to a method for preparing carbon fiber products. Background technique [0002] Carbon fiber (CF for short) is a new type of fiber material with high strength and high modulus fiber with a carbon content of more than 95%. It is a microcrystalline graphite material obtained by piling up flake graphite microcrystals and other organic fibers along the fiber axial direction, after carbonization and graphitization. Carbon fiber is "flexible on the outside and rigid on the inside". Its mass is lighter than that of metal aluminum, but its strength is higher than that of steel. It has the characteristics of corrosion resistance and high modulus. It is an important material for national defense, military and civilian use. It not only has the inherent characteristics of carbon materials, but also has the soft and processability of textile fibers. It is a new generation of ...
