Structural foam layer 2, except being evenly arranged through hole 3, also having and extends and the groove 4 be evenly arranged in branch-like, and groove 4 adopts the mode of cutting to process.Hole 3 and groove 4 interlock layout, except increasing the intensity of structural foam, are also convenient to the infiltration of resin 101 on structural foam, are further easily reinforced by the frp layer 1 on structural foam layer 2 both sides, thus improve the physical characteristic of housing.
Structural foam layer Main Function is heat-insulating sound-insulating, in the present embodiment, in order to improve the shock-absorbing capacity of structural foam layer, reach the object improving trailer shell intensity, durability and impact resistant capability, further hole 3 can also be processed, described hole 3 extends and penetrant structure foam in the shape of a spiral, and its two ends, aperture are large, middle little.Described groove 4 extends in branch-like and is evenly arranged in the surface of structural foam layer.Experiment proves, helical form is arranged in hole 3, groove 4 is arranged to branch-like, be arranged to common linear than by hole 3 and groove 4, intensity and the impact resistance of case material improve 30%-50%, have and obviously promote effect.
As other embodiments optional, the inner side of described shell mechanism can also be fixed with interior trim clamping plate, conveniently can make the finishing of interior cabin wall, realize certain decoration style; The outside of described shell mechanism can be provided with high density cere, thus prevents rainwater or dirty infiltration, makes shell more attractive in appearance, improves the service life of shell.
A processing method for the one-body molded shell mechanism of caravan, comprises the following steps:
1) master mold is made, and deployed resin, processing structure foam;
2) brush releasing agent on mould;
3) glue spraying clothing;
4) resinize, paving fibrage, compresses with steel rider, repeats this process, then resinize, make this layer of frp layer thickness reach more than 2.5mm;
5) when resin is not dry, paste structural foam, and resinize, make resin penetrate into structural foam;
6) resinize, paving fibrage, compresses with steel rider, repeats this process, then resinize, make this layer of frp layer thickness reach more than 2.5mm;
7), after solidification, repeatedly paste as required or demoulding finishing, obtained finished product.
In step 1), the making step of master mold is: first make wooden model according to vehicle shell, by scraping ash, polish, do flat, the male model of obtained 1 to 1, male model is waxed, and brush releasing agent, then resinizes successively on male model, paving fibrage, compress with steel rider, repeat this process, then resinize, after cure and demold, the master mold of obtained glass steel material.Master mold can be reused.
In step 1), resin 101 adopts fiber glass resin and proportion of filler to coordinate and forms, and carries out under 20 degree to 30 degree.Fiber glass resin, for being 70 by weight percentage, adopts epoxy resin, polyamino resin or phenolic resins etc.; Filler is by weight percentage 30, adopts talcum powder and quartz sand, also has curing agent etc., and preferably, curing agent adopts methyl ethyl ketone peroxide, and percentage by weight is 4, and also can adopt is that the ethylenediamine of 10 is as curing agent by weight percentage.For the bubble in removing fiber glass resin glue, can stir rapidly under vacuum conditions, carry out vacuum defoamation 2-5min.
In step 3), gel coat Main Function is the incrustation to glass fiber reinforced plastics product and the protection to structure sheaf.Model can be adopted to be the gel coat of 8373-w-9910, reinforcing glass steel layer surface property.
In step 4), paving fibrage pastes point wet method and dry method two kinds: 1. dry method laying: be raw material with prepreg cloth, is first cut into stock by learning material (cloth) in advance well by model, thermoplastic during laying, and then be close on mould layer by layer, and note getting rid of interlayer bubble, make closely knit.2. wet lamination: directly on mould by fibrage impregnation, be close to layer by layer on mould, deduction bubble, makes it closely knit.
In step 7), solidifying except the curing agent except adding in fiberglass and resin itself, also comprising and solidifying by external force.As follows specifically: when making master mold, the outside of male model is provided with deep floor, and make whole male model Stability Analysis of Structures, intensity is higher.Therefore, apply cure stage in external force, at glass fibre reinforced plastics casing inner surface, gripper shoe can be installed, reinforce in glass fibre reinforced plastics casing vertical direction force.
In sum, the whole trailer shell of the utility model is one-body molded, and casing rigidity is high, strong shock resistance, and simply easy to make, and efficiency is high, insulation and lightweight; Especially PMI foam providing holes, or/and groove, make housing have heat insulation, sound insulation hardness high, longer service life to adopt structural foam.
Above-described embodiment is illustrative principle of the present utility model and effect thereof only, but not for limiting the utility model.Any person skilled in the art scholar all without prejudice under spirit of the present utility model and category, can modify above-described embodiment or changes.Therefore, such as have in art and usually know that the knowledgeable modifies or changes not departing from all equivalences completed under the spirit and technological thought that the utility model discloses, must be contained by claim of the present utility model.
