Further, said structure is a three-dimensional braided structure, the fabric three layer or more of this three-dimensional braided structure for producing with three-dimensional woven or braiding, layer with layer between organically weave or be woven together with yarn; Different layers adopts material different to weave or weave according to different use needs.
Further, said three-dimensional braided structure is a preform constructions.
Further, said three-dimensional braided structure adopts three dimensional fabric liquid resin pressure to soak into curing molding, and cure under pressure forms said preform constructions three dimensional fabric injects liquid resin in mould after, and the shape of said preform constructions and said thin glass is identical.
Further, adopt the silica gel special bonding between said composite layer and the thin glass.
Further, the material of said composite layer employing is carbon fibre, aramid fiber, polyethylene fibre and spun glass.
Further, the expansion of said composite layer and contraction coefficient are identical with the expansion and the contraction coefficient of said thin glass.
Further, said thin glass is ultra-white float glass.
Further, said reflection horizon is a silver layer.
Further, the back side of said silver layer is provided with said reflection horizon protective seam, and said reflection horizon protective seam is copper layer or zinc layer.
The present invention adopts composite layer in condenser mirror; Improved the intensity of condenser mirror; Simplified the process that needs tempered glass among the original preparation technology; Thereby reduced manufacturing cost greatly, and then will reduce the photo-thermal power generation cost, it has solved the too high major issue of rate for incorporation into the power network cost in the current photo-thermal power generation.

Embodiment
Below, with reference to accompanying drawing, the present invention is more comprehensively explained, exemplary embodiment of the present invention has been shown in the accompanying drawing.Yet the present invention can be presented as multiple multi-form, and should not be construed as the exemplary embodiment that is confined to narrate here.But, these embodiment are provided, thereby make the present invention, and scope of the present invention is fully conveyed to those of ordinary skill in the art comprehensively with complete.
In order to be easy to explanation, here can use such as " on ", D score " left side " space relative terms such as " right sides ", be used for element shown in the key diagram or characteristic relation with respect to another element or characteristic.It should be understood that except the orientation shown in the figure spatial terminology is intended to comprise the different azimuth of device in using or operating.For example, if the device among the figure is squeezed, be stated as the element that is positioned at other elements or characteristic D score will be positioned at other elements or characteristic " on ".Therefore, the exemplary term D score can comprise upper and lower orientation both.Device can otherwise be located (revolve turn 90 degrees or be positioned at other orientation), and the relative explanation in used here space can correspondingly be explained.
Like Fig. 1, Fig. 2, Fig. 3, shown in Figure 4, three-dimensional composite material condenser mirror of the present invention comprises thin glass 1, sensitizing layer 2, reflection horizon 3, reflection horizon protective seam 4 from top to bottom, composite layer 5, external protection 6, and precision is combined as a whole between each layer.
Wherein, composite layer 5 is for adopting the structure of compound substance braiding, and said structure is a three-dimensional braided structure.Promptly produce the fabric more than three layers with three-dimensional woven or knitting skill.Layer with layer between organically weave or be woven together with yarn.Different layers can be weaved or weave according to different use needs with material different, thereby obtain to be weaved or woven article by what compound substance was formed, satisfy different use needs.The material that is used for fixing the reinforced glass sheet among the design is the production technology that adopts three dimensional fabric liquid resin pressure to soak into curing molding.Being about to three dimensional fabric puts into the mould that designs in advance and injects cure under pressure moulding behind the liquid resin.The shape of mould and glass sheet is identical, guarantees high-precision coincideing, and adopts the silica gel special bonding between three-dimensional composite material and the glass sheet.
The material that composite layer 5 adopts is carbon fibre, aramid fiber, polyethylene fibre and spun glass etc.During preparation, be divided into warp 7 and work out with parallel 8, layer is woven together with interlayer each other; Not only interlaminar strength significantly improves; And can obtain the preformed of labyrinth, promptly three-dimensional structure becomes preform constructions through the weaving or the braiding of compound substance, and this preform constructions can design according to the shape need of actual condenser mirror; Preformed composite layer 5 greatly facilitates itself and the combining of thin glass 1, and has simplified the treatment process in later stage.And because the compound substance Heat stability is good, thereby the expansion of optional compound substance and contraction coefficient are identical with the expansion and the contraction coefficient of thin glass 1, avoid in the process of expansion and contraction damage to glass.
Among the present invention; Three-dimensional braided structure is compared with existing laminar structure compound substance, and the large-scale production expense is low, and the rigidity of three-dimensional braided structure than the rigidity of identical panel material and geometry parameter laminate greatly near an one magnitude; Therefore; Through the research proof, in the mirror design, can adopt three-dimensional composite material to replace existing expensive heavy sheet glass catoptron.
