Description
Technical field
The present invention relates to a kind of compound external wall panel, relate in particular to the three-dimensional hollow fabric composite plate of a kind of inorfil and strengthen compound external wall panel, belong to building material field.
Background technology
Composite three dimensional braiding structure technology is a kind of novel advanced composite material growing up the eighties in 20th century, is low cost of future generation, lightweight, high damage tolerance and long-life material.First this technology is based on the considering of National Security Strategy, and is applied on space flight and aviation, sophisticated weapons, and up to now, different in nature three dimensional fabric is still that first develop and key technology with keen competition study hotspot and countries in the world.Then, gradually apply to the fields such as aircraft, boats and ships, track traffic, wind-powered electricity generation, chemical industry and sports.
The eighties, Nan Bo institute etc. has born the supporting development task of stereo fabric for the critical components such as heat insulation material and electromagnetic wave transparent material.Tianjin University of Technology, Donghua University start the research of three-dimensional woven design principle, and developed without the boundless yarn 3 D stereo of shuttle fabric manufacture equipment, realized weaving of three-dimensional woven fabric, research emphasis turns to the different in nature fabric of military most advanced and sophisticated purposes, and succeed, so China is second country that grasps this technology in the world.
General three-dimensional hollow fabric composite plate is all to be solidified and make through impregnation by three-dimensional spacer fabric (three dimension stereo fabric), impregnation and solidify and can produce fiber reinforcement effect to fibrous material, impregnation, solidify after the mechanical property of fiber much larger than impregnation, solidify before.Therefore early stage three-dimensional spacer fabric is produced substantially on double-needle bed raschel machine, and the inorganic fibers larger due to fragility should not weave, and space fabric is at that time all to using organic fiber yarn to weave as material.In the space fabric of knitting forming, can see that organic fiber yarn mutually goes here and there cover and form coil.Although the actual needs at that time of having released the solution to a certain degree of this space fabric purely being knit out as yarn by organic fiber.Therefore but the fiber reinforcement effect of organic fiber is little, this pure three-dimensional hollow fabric composite plate being made by organic fiber yarn is aspect compressive property or not ideal enough.Therefore subsequently, on market, there is people to propose to utilize high-performance fiber to transform above-mentioned three-dimensional hollow fabric composite plate, increase the crushing resistance of whole three-dimensional hollow fabric composite plate, so-called high-performance fiber refers to the large fibers of fiber reinforcement effect such as glass, carbon fiber, high molecular weight polyethylene fiber, aramid fiber, and the fragility of this fiber own is also unsuitable for crooked braiding more equally.
Publication number is that the Chinese patent of CN 101519827A discloses: " a kind of three-dimensional preparation method of compiling space fabric that strengthens is produced on the double-needle bed raschel tricot machine with full width weft insertion device through transformation.The raw material main body that the method adopts is the high energy fibre bundles such as glass fiber, carbon fiber, aramid fiber, ultra high modulus polyethylene, X-direction by machine before and two weft-thread insertion apparatus installing additional after machine on whole machine fabric width, introduce high-performance fiber stuffer weft; Y-direction is combed and is introduced high-performance fiber laying-in yarn by guide; With common or synthetic fiber in high strength filament yarn, with chaining or warp plain stitch, laying-in, stuffer weft being carried out to bondage fixes; Upper and lower top layer connection yarn adopts high-performance fiber equally, guarantees to keep 5-6cm spacing between two top layers ... ".The method is by X and the Y-axis of the surface layer at organic fiber space fabric, in Z-direction between the X of backing layer and Y-axis and surface layer and backing layer, all introduce high-performance fiber, use organic fiber that lopping performance is good on surface layer and backing layer, the intersection point of these high-performance fibers to be carried out to " bondage " with the organizational form of " chaining " or " through flat " fixing simultaneously, its emphasis is to bundle by organic fiber the high-performance fiber that is difficult to lopping, and reduce the frictionally damage between high-performance fiber, make high-performance fiber performance fiber reinforcement effect after impregnation solidifies, the final three-dimensional hollow fabric composite plate with better crushing resistance that obtains.The method has the feature of high fiber reinforcement effect and common organic fiber by high-performance fiber and has flexibility and can lopping feature carry out combination, and the crushing resistance of the final three-dimensional hollow fabric composite plate the obtaining composite plate before comparing is enhanced.
Yet although above-mentioned these high-performance fibers have high fiber reinforcement effect, itself stiffness before impregnation solidifies is also bad.Particularly after fabric completes impregnation, the deadweight meeting of " upper and lower top layer " obviously increases, and the deadweight that wherein surface layer increases directly imposes on " connection yarn " and causes " connection yarn " to be serpentine crouching down and be connected between upper and lower top layer.Along with the curing process further three dimensional fabric being carried out, this serpentine state of crouching down of connection yarn is got off by persistence.
Along with " twisting process " of fiber being further developed and maturation, through the basalt fibre of " twisting ", can meet the requirement of weaving.On market, also occurred that whole whole use inorfil weaves and curing composite plate, this composite plate is better than the above-mentioned three-dimensional hollow fabric composite plate being mixed by organic fiber and inorfil in mechanical property.As: notice of authorization number has disclosed for the patent of invention of CN2923306Y: " a kind of enhancing composite plate; there is stereo fabric core; it is long that stereo fabric core has the fabric that 2-6 the warp of being made by Inorganic Non-metallic Materials and parallel braiding form; be the 8-shaped connection of standing by connecting warp interval between upper and lower corresponding position between fabric face layer, fabric face layer is all coated with resin bed with the outside that is connected warp.The stereo fabric core of this enhancing composite plate is made network structure by glass fiber, carbon fiber or basalt fibre and is formed after resin compounded, when fiber absorbs after resin solidification, can add high tension and keep strong.Although this enhancing composite plate has further raising in intensity, but it connects warp and is still serpentine at the pressure of surface layer and crouches down and be connected between upper and lower top layer, " between fabric face layer, by connecting warp interval, between upper and lower corresponding position, be the 8-shaped connection of standing ".Because connection warp is exceptionally straight not, caused this composite plate the crushing resistance of inorfil can not be performed to maximum.
Comprehensive above-mentioned prior art is known, real straight and upright of the connection warp of existing three-dimensional hollow fabric composite plate all cannot form before and after the resin solidification, be all the state of crouching down that is crooked, can only crouch down the hardening of stateful connection warp by resin solidification relief and improve afterwards intensity.
Summary of the invention
The technical problem to be solved in the present invention is to propose a kind of three-dimensional hollow fabric composite plate all before and after resin solidification with the connection warp of exceptionally straight state.
The present invention is that the technical scheme that solves the problems of the technologies described above proposition is: a kind of three-dimensional hollow fabric strengthens composite plate, comprise the three dimension stereo fabric that is coated with resin bed, three dimension stereo fabric comprises surface layer and the backing layer by the woven one-tenth of inorfil graticule, between surface layer and backing layer, is connected with by first of inorfil warp knitting and is connected warp; Between surface layer and backing layer, be also connected with the warp that is connected with first of being made by high-intensity fiber and near second of braiding, connect warp side by side, the second length that connects warp is more than or equal to the length of the first connection warp.
Wherein, second connects warp for the first connection warp is produced to exceptionally straight effect.
Applicant of the present invention finds after great many of experiments: connect resistance to compression that warp is the three-dimensional hollow fabric composite plate of the exceptionally straight shape of " 1 " font and be much better than connection yarn and be the three-dimensional hollow fabric composite plate that serpentine is crouched down; Even directly whether without the yarn of woven fabric, concern the degree of giving full play to of inorfil Potential performance.Based on this, applicant's combination of the present invention experiment and research for many years, draws technique scheme.The beneficial effect of this technical scheme can be summarized as follows:
1, between the surface layer at fabric of the invention and backing layer, arrange be connected with first warp side by side near and the high-intensity fiber second connection warp with high initial stiffness, when after weaving textile moulding, high-intensity fiber second connects warp because it has compared with high initial stiffness and stand between surface layer and backing layer.Even after impregnation, the deadweight that surface layer increases because of impregnation is all applied on this high-intensity fiber and also can make it produce lodging, because the length that high-intensity fiber second connects warp is more than or equal to the length of the first connection warp, so the deadweight of the overwhelming majority of surface layer connects warp by high-intensity fiber second, is born and can be applied on the first connection warp again.Be connected warp with high-intensity fiber second and connect under the exceptionally straight effect of warp and keep tight until the curing of whole three dimension stereo fabric completes at this high-intensity fiber second near the first connection warp arranging, therefore connect warp and before and after resin solidification, all there is exceptionally straight state.The present invention fully carries out combination cleverly by the high fiber reinforcement effect of low initial stiffness of the high initial stiffness low fiber reinforcement effect feature of high-intensity fiber and inorfil, has obtained a kind of novel three-dimensional hollow fabric composite plate with exceptionally straight connection warp.High-intensity fiber the second connection warp is set can be played: (1) can, at the beginning of three dimension stereo fabric is being produced, make the inorfil jointly arranging with high-intensity fiber in vertical state, thereby inorfil can carry out impregnation under erectility; (2) successfully manage the surface layer situation that deadweight can increase after impregnation, arrange after high-intensity fiber, the pressure by high-intensity fiber opposing from surface layer, has built a condition that can be vertically curing to inorfil.
2,, with respect to the present invention, in background technology, publication number is that the Chinese patent of CN 101519827A is only in the method for the three-dimensional bondage high-performance fiber of the three dimension stereo fabric of being made by organic fiber, to improve the crushing resistance of composite board.Its starting point is to want to utilize the high fiber reinforcement that high-performance fiber has to be used for improving the final crushing resistance of whole composite plate, and its gimmick also still only rests on the aspect that material is replaced.And, between surface layer and backing layer, also only there is high-performance fiber connection yarn and do not have the connection yarn of other material.Although high-performance fiber has high fiber reinforcement feature, high-performance fiber is stiffness bad before impregnation solidifies.Particularly after above-mentioned fabrics completes impregnation, the deadweight meeting on " upper and lower top layer " obviously increases, the deadweight that wherein surface layer increases directly imposes on " connection yarn ", cause " connection yarn " can be serpentine and crouch down and be connected between upper and lower top layer, reduced the final crushing resistance of composite plate.In publication number is the disclosed technical scheme of Chinese patent of CN 101519827A, do not mention any technological means that can make " connection yarn " to become and stand upright yet, and be expressed between " upper and lower top layer " and do not exist yet and mainly work the fiber of assisting exceptionally straight effect according to its disclosed technical scheme.
3, same, another notice of authorization relatively of the present invention number does not disclose the technical scheme that the connection warp between any can making " top layer up and down " becomes exceptionally straight for the patent of invention of CN2923306Y yet.
4 and the present invention by arrange high-intensity fiber second connect warp method obtained the three-dimensional hollow fabric composite plate with tight connection warp, tight curing connection warp compressive property is far longer than the connection warp that is the figure of eight or " S " font.Therefore guaranteeing under the constant prerequisite of compressive property, can greatly reduce the consumption of fiber, reduced cost, alleviate weight, promoted construction safety degree, it is worth mentioning that the present invention is only set up in parallel high-intensity fiber and connects warp by be connected warp with inorfil, with regard to solved that people want to solve for a long time always and insoluble: how to make to connect the technical problem that warp does not bend.
