Description

technical field

[0001] The invention relates to the technical field of high-performance aluminum-based composite materials, in particular to a method for preparing an inorganic fullerene aluminum-based composite material for a fan containing casing. Background technique

[0002] The fan rotor blades of a civil turbofan engine rotate at high speed in the engine when it is working. Under the action of foreign object impact or internal damage, if the fan blade fails and breaks and flies out, it needs to be effectively contained by the fan casing, otherwise the fan fragments are likely to break down airframe and endanger flight safety.

[0003] Domestic and foreign airlines put forward strict inclusive requirements for the fan containment case of civil turbofan engines, such as China's "Aero Engine Airworthiness Regulations" (CCAR-33) and "Aero Turbine Engine Inclusive Requirements" (GJB3366-1998), And the United States "Engine Structural Integrity Program" (MIL-STD-1783B) and ...
