Abstract

The invention discloses a preparation method of a flame-retardant conductive paper / glass fiber composite. The method comprises the steps as follows: carbon oxide nanotubes are prepared and filled with nano silicon, silicon filled carbon oxide nanotubes are obtained and then added to a graphene oxide suspension, a mixed solution is obtained, conductive paper is further prepared and subjected to high-temperature curing composition with glass fiber prepreg, and the flame-retardant conductive paper / glass fiber composite is prepared. The prepared conductive paper has the strength of 15 MPa or above and the elongation at break of 1.5% or above. The maximum heat release rate of the prepared flame-retardant conductive paper / glass fiber composite is 190-210 kw / m<2> and is 35.7%-41.9% lower than the heat release rate of common flame-retardant conductive paper / glass fiber composites, and the flame-retardant performance is improved.

Description

technical field [0001] The invention relates to a preparation method of conductive paper / glass fiber composite material. Background technique [0002] Resin-based composite materials have the characteristics of low density and high strength, which greatly improves their application ratio in civil and military fields. For example, the interior and exterior decoration parts of the load-bearing structures of transport airliners and automobiles, the infrastructure of civil buildings, public places, and even the heat-resistant coatings of military fighter jets and structural parts of launch vehicles and satellites in the aerospace field are widely used in resin-based composites. Material. While resin-based composites bring so many advantages, they also have some potential application hazards, such as higher flammability and toxicity. Because the vast majority of resins are organic components, they are highly flammable and emit toxic gases. Therefore, when the main body of the ...
