Art, specifically a kind of microwave of multidirectional carbon fibre reinforced composite are heating and curing method.
Background technology
Advanced composite material has that specific strength and specific modulus are high, anti-fatigue performance is good, corrosion resistance and good and global formation
Property many excellent specific properties such as good, widely apply composite not only can substantially mitigate the construction weight of aircraft on aircraft, improve
Aeroplane performance, amount of parts can also be greatly reduced, simplify assembly process, shorten the manufacturing cycle.Composite is wide at present
The general primary load bearing part for wing and fuselage, the dosage on the complex curved surface parts such as air intake duct is more and more, and to entirety
Shaping, co-curing direction are developed.
At present, composite is mainly molded using autoclave technique heat-pressure curing.Solidification of hot-press tank technique is with resistance
Circulated after silk heating air under fan action, composite, composite wood are heated in a manner of heat convection and heat transfer
Material surface is first heated, and then transfers heat to inside.The rate of heat addition of multiple material part is slow, the temperature difference is big, molding cycle length, and air and
Mould is both needed to be heated to high temperature, high energy consumption.The Composite Microwave that inventor herein proposes early stage is heating and curing shaping technique
It is directed through with electromagnetic wave, inside and outside while uniform heating composite, firing rate is fast, short molding cycle.Microwave only heats multiple
Condensation material, air do not heat with mould, and energy consumption is low.
Although Composite Microwave heating technique has above-mentioned advantage.But microwave current can not be directed through heating multidirectional paving
Layer continuous carbon fibre reinforced resin based composites.The problem seriously constrains the development of Composite Microwave curing technology with answering
With so that the multidirectional laying continuous carbon fibre reinforced resin based composites widely applied on aircraft can only use microwave heating to inhale
Wave material delivers heat to composite, i.e. indirectly heat solidification composite（Patent：201310143863.X）.For above-mentioned difficulty
Topic, the present invention proposes a kind of microwave solidification method of multidirectional carbon fibre reinforced composite, by being answered in multidirectional fibre reinforced
The internal motivation of condensation material part vertically penetrates microwave and it is carried out to directly heat solidification.The present invention breaches multidirectional laying carbon
Fibrous composite part can not microwave heating problem, for Composite Microwave curing technology commercial Application provide theory according to
According to technical support.
The content of the invention
The purpose of the present invention be for multidirectional carbon fibre reinforced composite part can not microwave heating problem, invention is a kind of
The microwave that is directed through of multidirectional carbon fibre reinforced composite is heating and curing method.Experiment finds that its reason is：Composite
Being heating and curing for itself is realized by the electric field energy absorbed in microwave cavity.Direction of an electric field in cavity can be decomposed into parallel
In composite material surface and perpendicular to composite material surface.Can be in the carbon fibre of all directions parallel to the electric field of composite material surface
Induced-current has been encouraged in dimension, former electric field is shielded so as to produce corresponding reversed electric field.Perpendicular to the electric field of composite material surface
（It is defined as vertical microwave）Although will not be shielded, the direction of propagation of its energy equally can not parallel to composite material surface
Realize that multidirectional laying carbon fibre reinforced composite part is directed through heating.
A kind of use of present invention protection vertically penetrates the side that microwave directly heats multidirectional laying carbon fibre reinforced composite
Method, the problem that multidirectional laying carbon-fiber composite material can not be heated by microwave is broken through, realizes that the advanced multidirectional fibre reinforced of aviation is answered
Condensation material part is directed through being heating and curing,
The technical scheme is that：
A kind of microwave that is directed through of multidirectional carbon fibre reinforced composite is heating and curing method, it is characterised in that：By more
Vertically microwave is penetrated to the internal motivation of carbon fibre reinforced composite part it is carried out to directly heat solidification.
Metal strip is placed in multidirectional carbon fibre reinforced composite piece surface.Between composite and metal strip absolutely
Edge.Composite system with metal strip is placed in microwave cavity.Microwave in cavity is in the presence of metal strip
Risen in composite material parts internal motivation and vertically penetrate microwave, be directed through heating multidirectional carbon fibre reinforced composite, completed
Part solidifies.
The present invention is entered by vertically penetrating microwave in the internal motivation of multidirectional carbon fibre reinforced composite part to it
Row directly heats solidification.Multidirectional laying carbon fibre reinforced composite part is placed in microwave heating chamber body, on part
Metal strip is placed in surface or lower surface（Or place metal strip in part upper and lower surface）.Put between part and metal strip
Insulation film is put, ensures to insulate between material part and metal strip again, is mutually not turned on.Microwave in cavity is on metal grizzly bar
Electric charge is caused to be redistributed（Some regions can assemble a large amount of positive charges, and some regions can assemble a large amount of negative electrical charges）, in composite wood
Material inside parts, which have encouraged, vertically penetrates microwave（Direction of an electric field is along part normal direction, the direction of propagation in the micro- of inside parts
Ripple）, it is directed through heating multidirectional carbon fiber enhancement resin base composite material, completes part solidification.Multidirectional laying fibre reinforced
Composite mainly include thermoplasticity and the thermosetting resin based composites of continuous carbon fibre enhancing, ceramic matric composite,
Metal-base composites etc..Metal gate is the effigurate metallic conductor of tool（Such as rectangular-bar copper）, deposit between a plurality of metal gate
In a determining deviation, mutually it is not turned on.
Beneficial effects of the present invention：
The present invention breaches the problem that multidirectional laying carbon fibre reinforced composite part can not be heated by microwave, realizes aviation
It is being directed through of advanced multidirectional carbon fibre composite, inside and outside while be uniformly heating and curing.
