Abstract
This method relates to a kind of method of global formation composite shape for hat muscle, through the following steps that realize: use water-soluble core mould cladding PMI foam to prepare mould；Precast body prepared by this mould；Use VARI technique injecting glue, solidification；The water-soluble core mould using scour without sediment motion PMI foam outer cladding i.e. can get the shape for hat muscle of global formation；The invention has the beneficial effects as follows: compared with traditional semi-closed molds difficulty demoulding, it is possible to achieve fast demoulding；Compared with all using water-soluble core mould, material cost can be reduced.Use this invention can realize global formation composite shape for hat muscle, join riveting etc. with all parts after being manufactured separately to compare, on the premise of meeting overall performance requirement, by reducing securing member quantity, alleviate construction weight further, reduce manufacturing cost and assembly cost.
Description
Technical field
The present invention relates to the manufacture method of a kind of molding advanced composite material (ACM) shape for hat muscle, particularly relate to a kind of global formation new
The method of type composite shape for hat muscle.
Background technology
Traditional composite shape for hat muscle molding mode is mainly separately formed web and muscle, then carries out web and muscle
Surface processes, and by glueing joint and realizing by the way of riveting, operation is loaded down with trivial details, takes time and effort.
Therefore the most a lot of composites all use the mode of global formation to manufacture shape for hat muscle, both can improve molding effect
Rate, decreases the inputs such as assembling material requested, manpower, time, and while reducing cost, product intensity have also been obtained raising.And
The when of global formation, use water-soluble core mould the most completely is as mould now, the most relatively costly.
Summary of the invention
The technical issues that need to address of the present invention there is provided a kind of global formation composite shape for hat muscle manufacture method, logical
Cross minimizing securing member quantity, alleviate construction weight further, reduce manufacturing cost and assembly cost.
A kind of method of global formation composite shape for hat muscle, comprises the following steps:
(1) in metal die, PMI foam surrounding is uniformly coated with water-soluble core mould；
(2) by vacuum bag pressure, water-soluble core mould is compacted；
(3) by moisture in baking oven for heating eliminating core, the mould of water-soluble core mould cladding PMI foam is obtained；
(4) lay precast body on mould；
(5) VARI technique injecting glue, solidification are used；
(6) water-soluble core mould using clear water to wash away PMI foam outer cladding can get the shape for hat muscle of global formation.
Compared with prior art, the invention has the beneficial effects as follows: compared with traditional semi-closed molds difficulty demoulding, permissible
Realize fast demoulding；Compared with all using water-soluble core mould, material can be saved again, reduce material cost.Use this
Bright realize global formation composite shape for hat muscle, join riveting etc. after being manufactured separately with all parts and compare, overall meeting
On the premise of performance requirement, construction weight can be alleviated further by reducing securing member quantity, reduces manufacturing cost and be assembled into
This.Using water-soluble core mould cladding PMI(Polymethacrylimide) foam prepares mould and decreases the consumption of water-soluble core mould.
Accompanying drawing explanation
Fig. 1 is the schematic diagram of embodiment of the present invention global formation advanced composite material (ACM) shape for hat muscle mould；
Fig. 2 is the view of embodiment of the present invention global formation advanced composite material (ACM) shape for hat muscle precast body preparation note.
Detailed description of the invention
With detailed description of the invention, the present invention is described in further detail below in conjunction with the accompanying drawings:
From Fig. 1, Fig. 2:
The method of global formation composite shape for hat muscle.Including
By PMI(Polymethacrylimide in metal die) foam 1 surrounding is uniformly coated with certain thickness water-soluble core mould
2；
By the way of vacuum bag pressure, water-soluble core mould is compacted；
By moisture in baking oven for heating eliminating core, finally give the mould of water-soluble core mould cladding PMI foam；
Mode lay carbon fibre fabric precast body 3 according to Fig. 2；
Use VARI(Vacuum Assisted Resin Infusion: vacuum auxiliary resin penetration molding) technique injecting glue, solid
Change；
The water-soluble core mould using clear water to wash away PMI foam outer cladding can get the shape for hat muscle of global formation.
Web and muscle global formation can be eliminated the flow process of assembling by the present invention.
The present invention uses water-soluble core mould cladding PMI foam to prepare mould, compared with all using water-soluble core mould, again
Material can be saved, reduce material cost.
The present invention, after solidification terminates, uses clear water to wash away the water-soluble core mould of PMI foam outer cladding, can realize easily
The demoulding.
Claims (1)
