Abstract
The utility model relates to a glass fiber reinforced plastics sandwiched laminate which comprises an upper layer and a lower layer which are overlapped mutually and formed by a plurality of layers of glass fiber braided fabrics; a sandwiched laminate is arranged between the upper layer and the lower layer; and the glass fiber reinforced plastics sandwiched laminate is characterized in that the sandwiched laminate arranged between the upper layer and the lower layer is a plurality of foaming polyurethane boards which are parallelly arranged at intervals. The glass fiber reinforced plastics sandwiched laminate is formed as follows: firstly the upper layer and the lower layer are mutually overlapped and then are infiltrated and cured by resins, the upper layer and the lower layer are formed by a plurality of layers of glass fiber braided fabrics, the plurality of foaming polyurethane boards are parallelly arranged at intervals between the upper layer and the lower layer, and the cross sections of the foaming polyurethane boards are triangular or trapezoidal. The glass fiber reinforced plastics sandwiched laminate has light mass, and bend strength superior to that of the common glass fiber reinforced plastics sandwiched laminate, and improves rigidity and is simple in machining process and low in production cost under the situation of not increasing the cost of the glass fiber sandwiched laminate, thus being widely applicable to the manufacture of products such as wind driven generator cabin room covers, diversion covers and the like.
Description
Technical field
The utility model belongs to technical field of wind power generator, especially a kind of fiberglass sandwich laminate.
Background technology
The frp layer pressing plate that uses in the products such as common cabin cover of wind power generator, kuppe mostly by fiberglass braided thing as wild phase, thermosetting or thermoplastic resin are made through laminating technologies such as hand pasting forming, resin transfer molding, vacuum assisted resin importing moulding as continuous phase.When if the frp layer pressing plate need be born bending load, in order to improve its intensity, often need to increase the number of plies of the fiberglass braided thing that constitutes the frp layer pressing plate, but can increase the thickness and the weight of frp layer pressing plate so greatly, both increase manufacturing cost and technology difficulty, also caused the unnecessary raising of hot strength.At present, some producer is that materials such as the foamed polyvinyl chloride, expanded polystyrene (EPS) acrylonitrile of 5mm～50mm are as filled board at used thickness, can also reach the needs that improve laminate compression strength, but the adding of expanded materials such as polyvinyl chloride, polystyrene acrylonitrile, cause the rising of frp layer pressing plate price, limited its extensive use.
Summary of the invention
The purpose of this utility model is to overcome the deficiencies in the prior art, and a kind of fiberglass sandwich laminate simple in structure, with low cost is provided.
The technical scheme that the utility model is taked is:
A kind of fiberglass sandwich laminate, comprise the upper and lower that stack mutually, the upper and lower constitute by the compound glass fibrous braid, battenboard is installed between the upper and lower, it is characterized in that: the battenboard of installing between the described the upper and lower is a plurality of polyurathamc plates that parallel interval is installed.
And the cross section of described polyurathamc plate is a triangle or trapezoidal.
And the height of described polyurathamc plate is 10～50mm.
Advantage of the present utility model and good effect are:
The utility model is stacked by the upper and lower mutually after resin infiltration curing is made, the upper and lower constitute by the compound glass fibrous braid, parallel interval is installed a plurality of polyurathamc plates between the upper and lower, and the cross section of this polyurathamc plate is a triangle or trapezoidal.This frp layer pressing plate has light weight, bending strength is better than simple glass steel laminate, significantly do not increasing under the glass fiber laminate condition of cost, improve its rigidity, and processing technology is simple, production cost is low, can be widely applicable for the manufacturing of products such as cabin cover of wind power generator, kuppe.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
Fig. 2 is the cross-sectional view of Fig. 1.
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 fiberglass sandwich laminate, shown in Fig. 1～2, stack mutually after resin infiltration curing is made by the upper and lower, the upper and lower constitute by the compound glass fibrous braid, the upper and lower are equipped with battenboard, innovation of the present utility model is: the battenboard of installing between the upper and lower is a plurality of polyurathamc plates 1 that parallel interval is installed, and the cross section of this polyurathamc plate is a triangle or trapezoidal, highly is 10～50mm.
In the present embodiment, the cross section of polyurathamc plate is trapezoidal, and it highly is 40mm.The upper strata is by 1500g/m
2The first compound carpet veneer 2,1080g/m
2First sandwich carpet veneer 3 and the 1500g/m
2The second compound carpet veneer 4 stack formation mutually.Lower floor is by 1080g/m
2The second sandwich carpet veneer 5,1500g/m
2The 3rd compound carpet veneer 6,1500g/m
2The 4th compound carpet veneer 7 and 1080g/m
2The 3rd sandwich carpet veneer 8 stack formation mutually.
Manufacture method of the present utility model is:
1. mould fully cleans, and applies releasing agent;
2. lay the 3rd sandwich carpet veneer, the 4th compound carpet veneer, the 3rd compound carpet veneer and the second sandwich carpet veneer from bottom to up successively make progress, put a plurality of polyurathamc plates in the upper surface parallel interval of the second sandwich carpet veneer, and then the lay second compound carpet veneer, the first sandwich carpet veneer and the first compound carpet veneer;
3. about the upper surface lay of the first compound carpet veneer and between the upper and lower apart from the mozzle that is 1m, and the covering vacuum film;
4. at mould outside lay exhaust pipe, bleed, make internal pressure in the mould that vacuum film covers less than-0.096Mpa, in mould, inject the unsaturated polyester resin or the epoxy resin of the interpolation certain proportion methyl ethyl ketone peroxide curing agent of capacity, after every layer of braid soaked into fully by resin, curing molding is removed vacuum film and mozzle, promptly obtains fiberglass sandwich laminate finished product.The utility model uses the polyurathamc plate to be battenboard, significantly improved the anti-moment of flexure ability of frp layer pressing plate, significantly do not increasing under the glass fiber laminate condition of cost, improve its rigidity, and processing technology is simple, production cost is low, can be widely applicable for the manufacturing of products such as cabin cover of wind power generator, kuppe.
