Abstract
The utility relates to an FRP (fiber reinforce plastic) laminated sheet which comprises a plurality of layers of glass fiber woven fabric that are laminated, and is characterized in that the glass fiber woven fabric comprises a surface layer, a middle layer and a bottom layer, wherein spacer layers are arranged between the surface layer and the middle layer as well as between the middle layer and the bottom layer. For the FRP laminated sheet, the surface layer and the bottom layer are made of CDFM combination mat, the middle layer is made of glass fiber chopped mat, the spacer layers made of glass fiber combination mat are arranged between the surface layer and the middle layer as well as between the middle layer and the bottom layer, and all the layers are laminated in a die, fully soaked by resin by adopting the vacuum infusion way and then solidified and molded, therefore, the FRP laminated sheet is obtained. When the FRP laminated sheet is manufactured, a diversion net is not needed, thus saving resin consumption, lowering cost, reducing the number of layers and improving working efficiency.
Description
Technical field
The utility model belongs to technical field of wind power generator, especially a kind of frp layer pressing plate.
Background technology
Product such as cabin cover of wind power generator, kuppe is made by the frp layer pressing plate, and that this frp layer pressing plate has is in light weight, rigidity is high, the advantage of thin thickness, adopts the vacuum assisted resin introductory technique during manufacturing.Its manufacture process is: with fiberglass braided thing being laid on the mould in layer, stack to specific thickness, at the good fiberglass braided thing the superiors lay water conservancy diversion net of lay, in mould, add unsaturated-resin or the epoxy resin that is mixed with the certain proportion curing agent, the compound glass fibrous braid is after resin fully soaks into, curing molding promptly obtains the frp layer pressing plate.Because product requirement frp layer pressing plates such as engine rooms of wind power generators, kuppe have the more number of plies, in conventional machining process, a lot of man-hours have been taken than the fiberglass braided thing shakedown of multilayer is unrestrained, and exist interlayer in conjunction with unreal quality risk, and the use of a large amount of water conservancy diversion nets, also caused the waste of resin.
Summary of the invention
The purpose of this utility model is to overcome the deficiencies in the prior art, provide a kind of simple in structure, with low cost and in conjunction with closely, can be made into the frp layer pressing plate of different shape.
The technical scheme that the utility model is taked is:
A kind of frp layer pressing plate comprises the fiberglass braided thing that multilayer stacks mutually, it is characterized in that: described compound glass fibrous braid comprises top layer, intermediate layer and bottom, is provided with wall between top layer and intermediate layer and intermediate layer and the bottom.
And described top layer and bottom are made by the CDFM composite felt, and the intermediate layer is made by glass chopped strand mats, and wall is made by glass fiber composite mat.
And described top layer and bottom are 1800g/m
2The CDFM composite felt, the intermediate layer is 300g/m
2Glass chopped strand mats, wall is 1500g/m
2Glass fiber composite mat.
Advantage of the present utility model and good effect are:
The utility model comprises by the CDFM composite felt makes top layer and bottom, the intermediate layer of making by glass chopped strand mats, be provided with the wall of making by glass fiber composite mat between top layer and intermediate layer and intermediate layer and the bottom, each stacked being placed in the mould, after the method that imports resin by vacuum makes each layer fully be soaked into by resin, curing molding obtains the frp layer pressing plate.Do not need lay water conservancy diversion net during manufacturing, saved the consumption of resin, reduced cost, reduced shop number of plies amount, improved operating efficiency.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
Fig. 2 is the cross-sectional view of Fig. 1.
Fig. 3 is the view that the frp layer pressing plate adds man-hour.
The specific embodiment
Below in conjunction with embodiment, the utility model is further specified, following embodiment is illustrative, is not determinate, can not limit protection domain of the present utility model with following embodiment.
A kind of frp layer pressing plate, shown in Fig. 1～2, stack mutually after resin infiltration curing is made by the compound glass fibrous braid, innovation of the present utility model is: the compound glass fibrous braid comprises top layer 1, intermediate layer 3 and bottom 5, is respectively arranged with wall 2 and following wall 4 between top layer and intermediate layer and intermediate layer and the bottom.Top layer and bottom are by 1800g/m
2CDFM composite felt (Chinese: short cut felt-long filament felt-twin shaft to cloth one composite felt, manufacturer: Spain sky can engineering textile (Shanghai) Co., Ltd.) make, the intermediate layer is by 300g/m
2Glass chopped strand mats make, wall is by 1500g/m
2Glass fiber composite mat make.
The CDFM composite felt be by twin shaft to cloth, long filament felt and glass chopped strand mats according to the composite braided a kind of glass fabric that forms of certain ratio, twin shaft mainly provides mechanical strength to glass layer, the long filament carpet veneer mainly provides the path of resin water conservancy diversion, it is very fast that weak point is cut carpet veneer infiltration resin, helps the infiltration of water conservancy diversion resin on depth direction.The glass chopped strand mats of intermediate layer and two wall effects and glass fiber composite mat all have preferably, and resin soaks into speed.
Manufacture method of the present utility model is as shown in Figure 3:
1. mould 6 fully cleans, and applies releasing agent;
2. from bottom lay 1800g/m upwards successively
2CDFM composite felt one deck, 1500g/m
2Glass fiber composite mat one deck, 300g/m
2Glass chopped strand mats one deck, 1500g/m
2Glass fiber composite mat one deck, 1800g/m
2CDFM composite felt one deck;
3. about the upper surface lay on top layer and between the upper and lower apart from the mozzle 8 that is 1m (for signal, not drawing among Fig. 3), at outer covering vacuum film 7 by actual size;
4. at mould outside lay exhaust pipe (not drawing among the figure), bleed, make internal pressure in the mould that vacuum film covers less than-0.096Mpa, in mould, inject the unsaturated polyester resin of the interpolation certain proportion methyl ethyl ketone peroxide curing agent of capacity, after all layers are soaked into fully by resin, curing molding is removed vacuum film and mozzle, promptly obtains frp layer pressing plate finished product.Frp layer thickness of compressive plate in the present embodiment is 6mm, can not increase the thickness of frp layer pressing plate significantly, satisfies the requirement of engine rooms of wind power generators, has both guaranteed the mechanical strength of frp layer pressing plate, and high efficiency when making, and cost is low.
