Description
Technical field
The utility model belongs to composite material curing molding field, and in particular to a kind of composite material is filled with microwave curing
It sets.
Background technique
Aerospace is formed with high performance resin based composites and mainly uses autoclave process at present, because when its solidification
Relatively high temperature and solidifying pressure are typically necessary to eliminate bubble caused by resin matrix in solidification process, such as T800
Carbon-fibre reinforced epoxy resin prepreg solidifies under conditions of 180 DEG C and 0.6MPa, to avoid dredging inside the product after solidification
Loose porous and poor mechanical property.
In conventional thermocompression tank curing process, due to the geometric dimension of composite product, material system and curing process
The difference of parameter can be different degrees of the uneven distribution for causing product internal temperature and curing degree, cause product to generate complicated
Internal stress, the shape Collaborative Manufacturing of composite product is seriously affected, especially for solidifying thick section parts, inside product
The defects of there are biggish temperature gradients, therefore the complicated internal stress generated can make product generate layering and MATRIX CRACKING, very
To being damaged product just during molding.
It, will be micro- because microwave has many advantages, such as that selectivity heating, heating speed is fast, homogeneous heating, penetrability is strong, thermal inertia is small
Wave technology is applied to composite material and solidifies field, can substantially reduce curing time, reduces production cost, obtains excellent product
Can, there is huge development potentiality.The patent right CN201610025303 that is formerly obtained such as present inventor,

The widely applied bottleneck of composite material is restricted through becoming, inexpensive non-autoclave forming technique is absurd fantastic in this background
It is raw.
Non-autoclave forming technique is a kind of inexpensive manufacture technology of composite material, main with autoclave forming process
Difference does not need to apply external pressure when being molding, abandons the autoclave to involve great expense, only with baking oven and pumped vacuum systems, therefore
The cured low production cost of composite material.This is better than autoclave forming process in terms of equipment molding and die cost.But
It is to obtain and solidify product with the composite material of autoclave forming process phase homogenous quantities, be the main mesh of non-autoclave molding technology
Mark.

The porosity of type aerospace main force support structure part should be lower than 1%, and the porosity of secondary load-carrying construction part should be lower than 2%, and traditional
Material prepreg solidify according to non-autoclave forming technique, product porosity can be up to 5%~10%.Hole
An important factor for being influence composite property, therefore reduce the porosity for solidifying obtained composite product and reach
The porosity level of the composite product of solidification of hot-press tank, it has also become the top priority of non-autoclave forming technique research.
That is, with the continuous development of resin material curing process, the little non-bearing component of some stress, people
It has begun with curing process outside autoclave and makes.But for aerospace such as T800 carbon-fibre reinforced epoxy resin
The composite materials such as prepreg, only the solidifying pressure by vacuumizing is far from enough, because solidifying pressure is inadequate, after solidification inside product
The defects of gap will be generated, and then substantially reduce the mechanical property of product.So for the advanced resin base of aerospace
Carbon fibre reinforced composite can't reach requirement using curing technology outside current existing autoclave.
Therefore, for save the cost and raising safety coefficient, high-pressure curing is being carried out to composite material without using autoclave
When, if the porosity of the high-performance composite materials of aerospace can be made also to be able to achieve the similar hot-press solidifying in autoclave
Effect, this is those skilled in the art's problem to be solved.Therefore, those skilled in the art need to develop and be used for accordingly
High performance resin base carbon fibre enhances the cured device and method of composite product.

It is uniform.
3, by composite heater and vibration device integrated setting in the utility model, so that composite product is shaking
It can continue to heat up or keep the temperature without cooling after dynamic and heat treatment to carry out heat cure, solidify the production of resulting composite product
Moral character can be more preferable.
4, it in a kind of specific embodiment, in the utility model, will not need especially to heat in composite product
Perhaps cured region is covered with micro-wave screening material does not cover microwave then to needs especially heating or cured region
Shielding material stays one or more gap, so that the microwave shadow shield part is formed by shield microwaves area and through microwave region.
Microwave generator generates microwave and enters and be dispersed in microwave cavity, and micro-wave screening material is not pasted to composite product
Region (penetrating microwave region) is internally heated or solidifies.Region (the screen of micro-wave screening material has been pasted on composite product
Cover microwave region) since microwave not can enter wherein, so these regions are absorbed less than microwave energy, and can only receive from electric heating
The whole heating of part 222.Therefore, it may make the utility model in such a way that the heating of microwave fixed point and electrothermal piece are integrally heated
Temperature is uniform everywhere in the curing process for composite product.Therefore, recombination energy field heating provided by the utility model is so that micro-
Wave especially can be heated and be solidified for the part of composite product, by certain concrete shape, material and size
After the heating parameters research of composite material work piece is clear, electrothermal piece is used in combination, whole heating is carried out to workpiece, may make heating
Solidification process entirety uniform, controllable, to obtain high performance product product.Or it is heated in the utility model in composite material
One layer of strong absorbing material is first set at the area of its outer surface before solidifying, enhances the microwave of portion on composite material
Energy absorption.The effect that microwave fixed point heating is integrally heated with electrothermal piece can equally be played.
In addition, the utility model be series of patents or patent application CN201610025303, CN201610027791,
The improvement and innovation done on the basis of CN201610027866, CN201610030557 and CN201710214268, if this
Have in utility model in the presence of not careful enough place is described, can refer to these patents or patent application is implemented.That is, this is practical
It is novel also to introduce the content comprising these patents or patent application.
The shape of the incubator can be any moulding such as cube and cylindrical body.In the prior art for solidifying T800
The autoclave of prepreg needs pressure resistance, and tank skin is thick and solid.And the incubator in the utility model need to only provide an atmospheric pressure or summary
Higher than the pressure of atmospheric pressure, so its cost is much lower.It is preferred that being arranged in the incubator other than microwave cavity in the utility model
There is the fan for hot gas convection current.The shake table is connected to the bottom plate of the microwave cavity using three or more helical springs
On, a spring preferably at least, which is each provided with, in the table top following four corners position of shake table is used to support shake table.
The above content is the further descriptions made in conjunction with specific preferred embodiment to the utility model, cannot recognize
The specific implementation for determining the utility model is only limited to these instructions.For the ordinary skill people of the utility model technical field
For member, without departing from the concept of the premise utility, several simple deductions and replacement can also be made, all should be considered as
Belong to the protection scope of the utility model.
