The specific embodiment
The present invention is described in further detail below in conjunction with the specific embodiment.
Fig. 1 is process chart of the present invention, and with reference to shown in Figure 1, the moulding process of the bionical cellular board of integrated band edge sealing may further comprise the steps:
(1) mould is prepared: before using with alcohol with the die surface wiped clean, uniformly spray the dryness releasing agent at the former die surface then, dry, coat oil-based release agent on the male mold surface, so that test specimen and mould separate smoothly after the moulding.
(2) formpiston preparation: will pour in the male mold (Fig. 2) after the fusing of formpiston material heating paraffin, when treating paraffin cooling deliquescing upper surface is struck off, be cooled to after room temperature paraffin solidifies, form removal can make paraffin formpiston (shown in Fig. 2 b right side), the formpiston that makes is placed in the former in order (Fig. 2 c, 2d).
(3) glue preparation: according to epoxy resin: the mass ratio preparation epoxy resin of curing agent: diluent=10:3:1.Selected epoxy resin is bisphenol A type epoxy resin (the E51 epoxy resin that Wuxi resin processing plant of stars new chemical materials Co., Ltd produces) in this experiment; The curing agent that adopts (curing agent 593 that the large magnificent environmental friendly material in Wuxi Co., Ltd produces) is the linear long chain structure, impels the resin high resilience after the curing, has increased the toughness of resin.The diluent that adopts is the reactive diluent 501 that the magnificent chemical industry of Wuxi City product Co., Ltd produces.Brittle break takes place in epoxy resin casting matrix immediately that do not add diluent after load reaches maximum, no obvious sign before destroying has very big emergentness.And the epoxy resin casting matrix that adds 10% diluent is after reaching maximum, and sample does not destroy immediately, certain plastic deformation occurred.But the shear strength of casting matrix and compressive strength hang down 1.5% and 3% respectively than the epoxy resin casting matrix that does not add diluent.Because the diluent 501 that uses in this experiment is reactive diluent, it can participate in the curing reaction of epoxy resin directly, becomes the part of epoxy resin cured product cross-linked network, to the performance not influence basically of solidfied material.This shows, a small amount of reactive diluent be added in the toughness that has increased solidfied material when not influencing condensate performance substantially.Therefore, according to epoxy resin viscosity test result, shearing test and compression test result, the proportioning of the epoxy resin adhesive liquid that the present invention adopts is epoxy resin: curing agent: diluent=10:3:1(mass ratio);
(4) lay down fibre, impregnation: formpiston is inserted in the process of former in aforementioned (2), adopt following two kinds of methods to add fiber and resin material according to fiber content then: when fiber quality content 10% or when following, the epoxy resin of fiber and preparation stirs, mixture has better flowability, can directly import them in the former; When fiber content is higher than 10%, in aforementioned insertion formpiston, import fiber toward the inside, a side space of inserting formpiston, import effect to save the importing time and to improve, wait the paraffin formpiston all to be inserted into former after, (these fibers can be used short fiber at surperficial layer overlay fiber again, long fibre, geotextiles, fiber cloth or their lamination, fiber of the present invention are the basalt short fibers.After finishing, in mould, pour the epoxy resin adhesive liquid that step (3) is prepared into.Need to prove that resin should be added, to guarantee that fiber is soaked into fully.Unnecessary resin will be overflowed during the capping pressurization, and therefore sample performance can be do not influenced.The composite material interface adhesion strength directly affects the stress transmission between fiber and the resin, thereby influences the physical and mechanical property of composite macroscopic view.When interface binding intensity was more weak, the crackle of Chan Shenging was very easy to along the fiber surface expansion under external force, thereby reduced the mechanical property of composite.In order to obtain the fibre reinforced composites of better mechanical property, adopt silane resin acceptor kh-550 that the basalt fibre surface is handled, improve the interface bonding situation between fiber and the resin.
(5) vacuumize: after finish aforementioned (4), vacuumize processing, to guarantee that fiber is soaked into fully.
(6) curing, the demoulding: mould is put into air dry oven under 55-60 ℃ of condition, heated 1 hour, be cured moulding, can the demoulding after resin solidification is complete.
(7) melt paraffin: the sample after the demoulding is put into 120-150 ℃ of baking oven, the formpiston fusion that allows paraffin make is flowed out, solidify after 1 hour, can make integrated cellular board sample (the integrated cellular board of the pure resin of Fig. 3 a, Fig. 3 b add the integrated cellular board of basalt fibre).
Present embodiment and embodiment 3, preparation contrast cellular board, lower panel and sandwich layer are one-body molded, and top panel and sandwich layer are by glueing joint combination.Thus, by such cellular board is carried out Mechanics Performance Testing, can compare the mechanical property of two kinds of different preparation methods (one method and how body formed method).
Gained cellular board concora test typical case load-displacement curve as shown in Figure 4.Under the flat compressed load action, cellular board load-displacement curve starting stage is linear, load slowly rises, after bonding layer was compacted, panel closely contacted with the honeycomb sandwich layer, and load-displacement curve is sharp increase linearly, when load reaches peak value, obviously distortion appears in honeycomb wall, and load descends to some extent, but after this load fluctuation changes.Reason is because the original upload stage, because the existence of bonding layer, and glued membrane has certain thickness, so the starting stage slope of a curve is less.When first peak value appearred in load-displacement curve, destroying appearred in the part honeycomb wall, and load slightly descends, but the honeycomb sandwich layer still can continue carrying, and the load fluctuation is risen.Hence one can see that, if traditional two-sided glued cellular board, the displacement meeting of starting stage can be bigger than one-sided glued plate in this experiment.Integrated cellular board is not then because there being glued layer, with regard to the displacement of this starting stage that can not occur occurring because of glued layer.Thereby the ability with better initial stiffness and resistance to deformation.
The cellular board concora test the results are shown in Table 1.
Table 1 concora test result
The flat crush resistance of composite wood stock column/foamed plastics sandwich structure relatively sees Table 2 in the flat crush resistance of the cellular board that integral process of the present invention obtains and the list of references.
Table 2 cellular board and composite wood stock column/foamed plastics sandwich structure relatively
| Kind | Density kg/m 3 | Compressive strength MPa | Specific strength (Nm) 2 |
| The cellular board that |
779 | 29.2 | 37,484 |
| Composite wood stock column/foamed plastics sandwich structure plate | 528 | 8.1 | 15,341 |
Annotate: the cellular board plate thickness is 2.3mm; Composite wood stock column/foamed plastics composite core material sandwich structure plate thickness is about 1.3mm.
Though the density of the cellular board of preparation is bigger than composite wood stock column/foamed plastics sandwich structure plate in this test, specific strength is about 2 times of latter's higher value.As mechanical property relatively, adopt specific strength and specific stiffness usually, under the suitable situation of quality, the specific strength of material and specific stiffness are more big, and the expression performance is more good.Therefore with regard to this index of specific strength, the prepared cellular board of the present invention has bigger specific strength.
Cellular board bend test result and typical failure mode respectively as Fig. 5, shown in Figure 6.The typical failure mode of cellular board under the bending load effect is: (1) bonding layer destroys, be that top panel and sandwich layer come unstuck, shown in Fig. 6 (a), sample splicing face exists defective or weak side to begin to occur the phenomenon that top panel and sandwich layer are peeled off in the loading procedure, continue along with loading, release surface is constantly extended to the middle part, can obviously hear the sound that sends when peeling off in the loading procedure.This kind failure mode has a strong impact on the performance (failure mode that the legacy cellular plate occurs easily) of material property.Analyzing possible reason is that bonding quality difference causes.When bonding quality was relatively poor, the failure mode that top panel and sandwich layer come unstuck often took place more than the intensity difference of lower panel in the glue-joint strength of top panel and sandwich layer under the bending load effect.
(2) lower panel fracture is as Fig. 5 (b), shown in Fig. 6 (b).(lower panel and the sandwich layer of embodiment 2 preparations are one-body molded, and top panel and sandwich layer are by the fracture mode of the cellular board of splicing combination).When bonding quality was good, panel and sandwich layer can bulk deformations, finally are to be met or exceeded the panel hot strength and the panel rupture failure is taken place by the lower panel tension
(3) upper and lower panel is excellent basically, destroys all occurring in the honeycomb sandwich layer.From the slope of load-displacement curve (Fig. 4 b) as can be known, article two, curve straightway slope is equal substantially, though hence one can see that bonding quality has considerable influence to the bending strength of structure, but the bending stiffness influence to structure is little, by as can be known, though be similarly panel and the sandwich layer destruction of coming unstuck, breaking load is widely different.Can set about from the splicing face of how body formed top panel and sandwich layer for this reason, analyze the reason that difference produces.Fig. 7 provided in the crooked experiment cellular board top panel and sandwich layer come unstuck destroy after, the destruction situation of bonding layer.By Fig. 7 (a) as can be known, contact with the honeycomb sandwich layer part of (bonding) of top panel, existing adhesive layer is stripped from (shown in the white arrow among the figure) into strips, have adhesive layer partly to be retained in (with among the figure shown in the asterisk) of top panel again, and this distribution is comparatively even.And in Fig. 7 (c), its right side is no glue-line district (shown in the broad arrow among the figure) in blocks.The cementing status itself that can infer each sample thus has bigger difference.Therefore the cellular board of traditional how body formed technology acquisition has the weakness that easy peeling off (coming unstuck) destroyed really.
The above-mentioned specific embodiment does not limit technical scheme of the present invention in any form, and every employing is equal to replaces or technical scheme that the mode of equivalent transformation obtains all drops on protection scope of the present invention.
