Description
Technical field
The utility model belongs to field of compound material, is related to rail traffic vehicles aramid fiber honeycomb skin structure.
Background technique
Currently, the exterior skin of rail traffic vehicles is generally prepared by glass reinforced plastic or aluminium sheet, all there is a problem of that weight is big, this
Outside, the unsuitable large area of lead-covering is integrally formed, poor rigidity, easily-deformable problem, although glass reinforced plastic covering can be integrally formed,
But product is not environmentally.Aramid fiber honeycomb sandwich structure composite material is compound by aramid fiber paper honeycomb and phenolic aldehyde/glass fibre laminate
Form, there is outstanding advantage in terms of loss of weight, be provided simultaneously with and its excellent flame retardant property, be suitble to large area disposably integral into
Type.
Traditional glass reinforced plastic skin product mainly uses vacuum to import the preparation of resin forming technique, and glass fabric is pressed
On the mold for brushing gel coat, sealing vacuumizes design scheme laying, is then sucked unsaturated polyester resin using vacuum, most
Curing molding afterwards.Lead-covering mainly passes through press punching press and prepares, and needs large press and metal.Traditional glass reinforced plastic covering produces
There are following major defects for product and lead-covering:
(1) traditional glass steel covering: product quality is excessive, in addition, because containing a large amount of in the unsaturated polyester (UP) used
Styrene, can volatilize a large amount of irritative gas in process of production, endanger producers' health.In product use process
In, it easily deforms.
(2) lead-covering: product quality is big, and it is integrally formed to be unable to large area, and large scale equipment is needed to put into.
Utility model content
The purpose of this utility model is that in view of the deficiencies of the prior art, the track of a kind of light weight and stable structure is provided
Vehicular traffic aramid fiber honeycomb skin structure.
In order to solve the above-mentioned technical problem, the technical solution of the utility model are as follows:
Rail traffic vehicles aramid fiber honeycomb skin structure, including aramid fiber honeycomb core material, the upper table of the aramid fiber honeycomb core material
Face and lower surface are compounded with phenolic aldehyde/glass fiber reinforced plastics laminates, and phenolic aldehyde/glass fiber reinforced plastics laminates and aramid fiber honeycomb core material pass through ring
Oxygen glue film is combined into one；Wherein, phenolic aldehyde/glass fiber reinforced plastics laminates matrix resin is phenolic resin, phenolic aldehyde/glass layer
The reinforcing fiber of plywood is glass fibre or glass fabric.
In this way, phenolic aldehyde/glass fiber reinforced plastics laminates are compound by epoxy jelly membrane and aramid fiber honeycomb core material, epoxy resin and phenol
Cementability between aldehyde/glass fibre prepreg, aramid fiber honeycomb core material is preferable, it is ensured that good adhesive strength, favorably
In the aramid fiber honeycomb sandwich structure composite material skin for obtaining stable structure, and the fire resistance of aramid fiber honeycomb itself is preferable, phenol
The fire resistance of urea formaldehyde and glass fibre is also preferable, can meet structural performance requirements, and can satisfy honeycomb skin to resistance to
The requirement of fiery performance.
Further, phenolic aldehyde/glass fiber reinforced plastics laminates are with a thickness of 0.2-5mm, preferably 0.5-4mm.
Further, the phenolic aldehyde/glass fiber reinforced plastics laminates are combined by multilayer phenolic aldehyde/glass fibre prepreg.
Further, the thickness 1-50mm of aramid fiber honeycomb core material, generally 5-45mm, preferably 10-40mm, it is further excellent
It is selected as 15-35mm.
The rail traffic vehicles aramid fiber honeycomb skin structure of the utility model can be used to be prepared following preparation method, specific to wrap
Include following steps:
S1, release agent is smeared on mold；
S2, the first phenolic aldehyde/glass fibre prepreg, the first epoxy jelly membrane, aramid fiber honeycomb core, are successively laid on mold
Then diepoxy glue film, the second phenolic aldehyde/glass fibre prepreg demould on the second phenolic aldehyde/one layer of glass fibre prepreg upper berth
Then cloth spreads one layer of isolation film, airfelt is put on isolation film, carries out vacuum bag sealing；
S3, it persistently vacuumizes, guarantees that vacuum degree more than -95kPa, entire mold is placed in baking oven and is heated and cured into
Type obtains rail traffic vehicles aramid fiber honeycomb sandwich structure composite material skin finished product；
Wherein, be heating and curing three Duan Jinhang of molding point, i.e., 0.8-1.2h is first kept the temperature under the conditions of 75-85 DEG C, then in 110-
0.8-1.2h is kept the temperature under the conditions of 130 DEG C, finally keeps the temperature 0.4-0.6h under the conditions of 140-160 DEG C.
Compared with prior art, the beneficial effects of the utility model are as follows:
(1) light weight, the product of same thickness, than traditional glass steel covering loss of weight 50%, than lead-covering loss of weight up to 100% with
On.
(2) easily molded, it is large-sized abnormally-structured, it can disposal integral molding.
(3) stable structure, good rigidity also have good fire prevention, heat-insulated and sound insulation value.
