Abstract
The utility model relates to a high performance foam layer board, top layer panel and middle core including upper and lower both sides, the core be through filling hollow microsphere the synthetic foamed material that the preparation obtained in the organic resin matrix material, the top layer panel fill the fibre reinforced composite that the preparation obtained in the organic resin matrix material mutually for the fiber reinforcement, the matrix material of top layer panel is the same with the matrix material of core, the utility model discloses a top layer panel of foam layer board can direct laminating on the core, may not need between top layer panel and the middle core to add extra gluing agent, have that mechanical properties height, water absorption rate are low, an easily shaping, equipment cost is low, production efficiency is high and the energy consumption is few advantage, but wide application in application sensitive to weight and that have relatively high expectations to the mechanical properties of material, like aviation material of construction.
Description
Technical field
The utility model relates to technical field of composite materials, particularly relates to a kind of high performance foamed sandwich structure.
Background technology
At present, most of composite sandwich structural is all use the traditional chemical frothing foam of perforate as core.Owing to being difficult to the defect of Controlling Technology parameter in chemical blowing forming materials process, there is the defects such as mechanical property is poor, easy water suction in conventional foam, this makes conventional composite sandwich material be difficult to meet some applications higher to mechanical property requirements.
Comparatively speaking, the formation basic theory of the foam structure of synthesising foam material and chemical blowing material have significant difference.It is enclosed in tiny balloon by some or intragranular pore forms.By selecting suitable tiny balloon, can well regulate and control the combination property of synthetic foam, as mechanical property and water imbibition etc., synthesising foam material is easy to shaping simultaneously, and cost of equipment is low, and production efficiency is high, the advantage of less energy consumption.
At present, in synthesising foam material, major part is all the document for its manufacture method and mechanical property research, becomes the document of sandwich plate then to rarely have report synthesising foam material Design and manufacture.
Utility model content
The purpose of this utility model is the above-mentioned defect for prior art, provides a kind of foamed sandwich structure of good mechanical properties.
In order to reach above-mentioned purpose of design, the technical solution adopted in the utility model is as follows:
A kind of high-performance foam sandwich plate, comprises the skin panel of upper and lower both sides and middle one deck core.Described core is synthesising foam material, and synthesising foam material prepares by being filled in organic resin by tiny balloon.Wherein tiny balloon is preferably high-performance hollow glass micropearl.
Described skin panel is fibre reinforced composites.Wherein fiber comprises glass fibre, carbon fiber etc. and yarn fabric thereof.
Favourable, the matrix material of skin panel is consistent with the matrix material of core.
The skin panel of foam layer plate of the present utility model can directly be laminated on core, can not need to add extra adhesive between skin panel and middle core.
The beneficial effect of foam layer plate described in the utility model is: have that mechanical property is high, water absorption rate is low, be easy to shaping, cost of equipment is low, production efficiency is high and the advantage of less energy consumption;
Accompanying drawing explanation
Fig. 1 is the structural representation of the foam layer plate described in the utility model embodiment.
Detailed description of the invention
As shown in Figure 1, a kind of high-performance foam sandwich plate described in the utility model embodiment, comprise upper and lower both sides skin panel 1 and between core 2.Core is that high-performance hollow glass micropearl is filled into the synthesising foam material prepared in epoxy resin-base.Skin panel uses glass fibre as the epoxy resin composite material of wild phase.
After only need being stacked by glass fibre before resin solidification time prepared by this novel foam sandwich plate, the organic resin using the method for vacuum bag pressure to guarantee in sandwich is uniformly distributed and good combination between skin panel and core.Then whole system at room temperature solidifies process 18 hours, and then post processing 2.5 hours at 120 DEG C.
Novel foam sandwich described in the utility model, is mainly used in weight sensitive and the application higher to the mechanical property requirements of material, as Aircraft Structure Materials.
