Height, chip heat-resisting quantity are poor, and radiate insufficient problem.The electronic equipment of aerospace craft heat control system tends to miniaturization, light weight
Change, compact-sizedization, operation are efficient, a large amount of heat can be generated and accumulate in operational process, if cannot export in time, electronics
The normal work of device and the stability of system will be severely impacted.Thus, it is led to as thermal control important component
Hot material is put forward higher requirements.The heat conduction and heat radiation rate for how improving heat sink material reduces the space occupied by it, increases material
Rigidity, hardness be the problem of Heat Conduction Material field is paid close attention to always.
Graphene has very due to its original two dimension structure feature and excellent chemical and physical properties in many fields
Big potential application.Glass fibre all shows excellent property in terms of insulating properties, heat resistance, corrosion resistance and mechanical strength
Energy.The two is compound, as packing material, crushing resistance, pull resistance and the impact resistance of substrate can be enhanced, while improving thermally conductive
Property and electric conductivity.However, being difficult graphene uniform being coated in fiberglass surfacing, meeting according to simple physical blending
Significantly affect its functionality.
Summary of the invention
In order to overcome the disadvantages mentioned above and deficiency of the prior art, the purpose of the present invention is to provide a kind of coatings of graphene
The preparation method of composite glass fiber, this method can effectively facilitate graphene uniform coated in fiberglass surfacing, obtain more function
The packing material of energy property, effectively improves the mechanical performance, conduction and heating conduction of material.
The purpose of the present invention is achieved through the following technical solutions:
A kind of composite glass fiber is coated in fiberglass surfacing by graphene；
A kind of preparation method of the composite glass fiber of the graphene coating, comprising the following steps:
