Glass fiber blanket with high heat conductivity

Abstract

The invention discloses a glass fiber blanket with high heat conductivity. The glass fiber blanket with high heat conductivity is characterized in that the glass fiber blanket is of a layer structure; a substrate is the glass fiber blanket, and an outer layer is a graphene layer; the thickness of the glass fiber blanket substrate is 5-10 mm; the graphene layer is made of monolayer graphene, multilayer graphene or a mixture of the monolayer graphene and the multilayer graphene; the thickness of the graphene layer is 0.1-10nm; the graphene layer contains silicon atoms, and the content of the silicon atoms and carbon atoms is 1%-3%. According to the glass fiber blanket with high heat conductivity, glass fiber serves as the substrate, so that the glass fiber blanket is low in cost; the graphene layer with high heat conductivity is arranged on the surface of the fiber, so that the mechanical strength of the whole glass fiber blanket is improved, and the heat conductivity of the whole glass fiber blanket is improved; the glass fiber can replace carbon fiber in a certain case; the glass fiber blanket with high heat conductivity has practicability and can be applied in various fields.

Description

technical field [0001] The invention relates to a glass fiber felt, in particular to a glass fiber felt with high thermal conductivity. Background technique [0002] Carbon fiber is a new type of high-strength, high-modulus fiber material with a carbon content of more than 95%. It is formed by stacking organic fibers such as flake graphite microcrystals along the axial direction of the fiber. The resulting microcrystalline graphite material. Carbon fiber has many excellent properties, such as good fatigue resistance, small thermal expansion coefficient, and good electrical and thermal conductivity. Except for thermal insulation materials, it is generally not used alone. It is mostly added to resins, metals, ceramics, concrete and other materials as reinforcing materials. It is widely used in many fields such as aerospace, national defense and military industry, and civil use. The thermal conductivity of carbon fiber with high thermal conductivity in the fiber direction can...
