Technical field
The invention belongs to aluminum alloy processing technology field, in particular to a kind of aluminium foil for being used to prepare lightning protection aluminium net
Material.
Background technique
Modern Advanced Aircraft largely uses advanced composite material to improve flying quality.Composite material can provide good
The strength and stiffness characteristic got well reduces weight, but its electric conductivity is not so good as metal material, cannot can incite somebody to action as metal material
The electric current and heat of lightning stroke promptly scatter, therefore the loss that composite material is struck by lightning is huge.In order to aircraft etc.
Aerospace structure composite material provides lightning Protection, can be by metallic conductor additives or by the metal mesh system of different structure
System is additional to composite material outer surface, to provide excellent electric conductivity, electric current is dispersed and is transferred out from attachment position, with
This reduces the physical hazard of lightning stroke incident.
Currently, common lightning protection metal mesh is mainly woven wire cloth and ductile metal net, material master both at home and abroad
It to be copper or aluminium.Overlap resistance is bigger between braiding silk screen wire, and lightning protection effect can not show a candle to ductile metal net, and
And braided metal silk screen is also easily broken off and is disintegrated due to the powerful electromagnetic force that lightning current generates.And the circuit electricity of ductile metal net
Hinder small, lightning current protective performance is good, and ductile metal net surface is uniform, will not influence the aeroperformance of aircraft.Therefore ductility
Metal mesh has become most important method in technique for aircraft composite lightning protection.
When carrying out the selection of ductile metal net, the ability for making metal mesh meet conduction electric current is first had to, then investigate ductility thunder
Lightning protection ability of the electric protective metal net under lightning current percussion.It finds after study, the conduction electric current of metal copper mesh
Ability and lightning protection effect are all got well than metal aluminium net, but the metal aluminium net of identical weight is than the conduction electric current energy of metal copper mesh
Power and lightning protection effect will be got well.
It is wherein critical material for the aluminum foil material of form metal aluminium net, and normal aluminium foil material is led in the prior art
The parameters such as electric energy power, ductility, intensity cannot reach the requirement for being used to prepare lightning protection aluminium net, and seine process is usually deposited
It is being difficult to be integrally formed, the easily broken problem of mesh muscle.
