Description

technical field

[0001] The invention belongs to the technical field of composite materials, and in particular relates to a boron nitride heterogeneous filler and a preparation method thereof, a fiber-reinforced epoxy resin heat-conducting composite material, a preparation method and application thereof. Background technique

[0002] Fiber-reinforced epoxy resin composite materials are often used in large-scale generator insulation tanks, UHV converter valves and reactors due to their advantages of high strength, good electrical insulation, easy molding and processing, excellent chemical stability and low cost. . However, with the development of high-power and high-integration electronic equipment, the thermal conductivity of fiber-reinforced epoxy resin composites cannot meet the requirements of use, which severely limits the application value of fiber-reinforced epoxy resin composites in conductive / heat-dissipating materials.

[0003] Researchers have improved the thermal ...
