Description
Technical field
The present invention relates to the manufacture field of composite, be the preparation of a kind of fibre reinforced composites crossbeam in detail
Method.
Background technology
It is known that composite crossbeam uses the moulding processs such as mold pressing, autoclave, pultrusion, and length (is more than greatly
3m), the above-mentioned technique of product utilization that Web shape is complicated, dimensional height is bigger is difficult to.Owing to web height is big, simple
Vacuum diversion is one-body molded, and web is difficult to fully infiltrate, and is easily caused the defect such as starved, dry spot.
Summary of the invention
In order to overcome the deficiencies in the prior art, the present invention provides the preparation method of a kind of fibre reinforced composites crossbeam,
It is applicable to the composite crossbeam that crossbeam length is big, Web shape is complicated prepare, there is low cost, simple to operate, product quality
Easily controllable, production efficiency advantages of higher.
The technical solution adopted for the present invention to solve the technical problems is: the preparation of a kind of fibre reinforced composites crossbeam
Method, it is characterised in that: by wet processing sub-unit molding, then by epoxy structural rubber solidification by cement molding, described divides
Parts-moulding, for by crossbeam is split into cover plate, web and three kinds of fiber component of lower cover, uses wet therapy forming process respectively
Separately formed, then use epoxy structural rubber that each unit construction is glued together, use and glued joint fixture cure under pressure molding.
Described wet processing is according to the shape designed, fabric to be carried out cutting, then according to Lay up design is suitable
Sequence is successively laid on mould；Lay release cloth, flow-guiding screen, injected rubber hose, exhaust tube successively on the superiors' fabric, surrounding patch is close
Sealing also seals with vacuum bag；It is evacuated to more than-950mbar, closes extraction valve and ensure that 5min internal drop is not more than
60mbar, then utilizes the liquid resin that viscosity is 200～600cpa atmospheric pressure to pass through injected rubber hose and injects the vacuum of negative pressure
Seal in bag, put into baking oven for heating solidification.
The invention has the beneficial effects as follows, it is adaptable to prepared by the composite crossbeam that crossbeam length is big, Web shape is complicated, tool
Having low cost, simple to operate, product quality is easily controllable, production efficiency advantages of higher.

Detailed description of the invention
Crossbeam shown in Fig. 1 is split into the upper cover plate 11 shown in Fig. 2, web 12 and lower cover 13, wet processing divides
Parts-moulding, then by epoxy structural rubber solidification by cement molding, described sub-unit is shaped to by crossbeam is split into lid
Plate, web and three kinds of fiber component of lower cover, use wet therapy forming process separately formed respectively, then use epoxy structural rubber handle
Each unit construction is glued together, and uses and glueds joint fixture 14 cure under pressure molding (as shown in Figure 3).
As shown in Figure 4, the concrete procedure of processing of the present invention is, designs mould 1, prepares shape and the chi of product for guarantee
Very little；Require to be laid on mould 1 according to Lay up design by fibrous material 2, lay release cloth 3, flow-guiding screen 5 the most successively, de-
The edge cladding exhaust tube 4 of mould cloth 3 carries out lay, at the length direction lay injected rubber hose 6 of fibrous material 2, injected rubber hose 6 will with lead
Drift net 5 EDGE CONTACT, edge region lay gum-injecting port 7 and bleeding point 8.Then arrange above lay material and ensure smooth aptychus
Wrinkle, pastes fluid sealant 9 in surrounding, and then paving vacuum bag 10 seals.Gum-injecting port 7 connects digital display vacuum meter, with vacuum pump by bleeding point 8
Carry out being evacuated to more than-950mbar, close bleeding point 8, and check digital display vacuum meter 5min internal drop to be not more than 60mbar.
After being verified, open bleeding point 8, the liquid resin mixed is made by gum-injecting port 7 in injected rubber hose 6 injects vacuum bag 10
Fibrous material 2 closes gum-injecting port 7 after being sufficiently submerged in, and entirety is put into baking oven and solidifies, evacuation to be continued in solidification process,
And ensure that vacuum bag is air tight, carry out the demoulding after solidification and post processing is machined to design size.
It is sequentially prepared upper cover plate 11 1, web 12 two pieces, lower cover 13 1, with 200 mesh～400 according to such scheme
It is the most coarse that face is gluedd joint in mesh sand papering, then cleans with acetone, dries, the two component epoxy structure glue mixed uniformly is coated
0.15mm～0.3mm on splicing face, assembles according to carrying out shown in Fig. 3 glueing joint, and enters curing oven after glueing joint fixture 14 clamping.
