Step 5), sticking carbon fiber restraint layer 1;
Step 6), solidification process: adopt cured 24 hours of inner die.
In technique scheme, described carbon fiber restraint layer 1 is carbon fiber board, then described step 5) comprise further: by carbon fiber board uniform application in stickup position, and with the repeatedly roll extrusion of special cylinder, squeeze bubble removing, make the well-bonded damping layer 2 of resin glue binding agent and carbon fiber board.
In technique scheme, described carbon fiber restraint layer 1 is carbon cloth, then lay multi-storey up-down and translation successively according to the carbon cloth grain direction certain angle that staggers, resin glue binding agent is all used to bond between layers, with the repeatedly roll extrusion of special cylinder, squeeze bubble removing, make resin glue binding agent fully soak into carbon cloth, and ensure that cylinder roll extrusion can not destroy carbon cloth.
The invention has the advantages that:
Lightweight Constrained Plates of the present invention adopts the fibrous material with equal tensile modulus of elasticity to replace metallic plate, ensure that damping-constraining effect, reduce restriction damping layer overall weight simultaneously, some overall weights restricted damping vibration attenuation design occasion can be solved very well.

Detailed description of the invention
Now the invention will be further described by reference to the accompanying drawings.
With reference to shown in figure 1, figure being by the object of vibration damping by vibration damping substrate 3, lightweight Constrained Plates of the present invention is arranged on this by vibration damping substrate 3, to realize vibration-damping function.Lightweight Constrained Plates of the present invention comprises: damping layer 2, carbon fiber restraint layer 1; Wherein, the one side of described damping layer 2 is pasted with described carbon fiber restraint layer 1, and the another side of described damping layer 2 is pasted onto described by vibration damping substrate 3.
Below the parts in lightweight Constrained Plates are described further.
Described carbon fiber restraint layer 1 adopts carbon fiber board or carbon cloth to realize.
The manufacture method of lightweight Constrained Plates of the present invention is as follows:
Step 1), process by the surface of vibration damping substrate 3, comprising: adopt sand papering smooth, then cleaned with acetone;
Step 2), by brushing resin glue binding agent on vibration damping substrate 3: with rotary broom by the resin glue binding agent uniform application that configures in by the surface of vibration damping substrate 3;
Step 3), coating damping layer 2: the lower surface of damping layer 2 is adopted acetone cleaning, whole damping layer is attached on substrate 3, and with scraper plate or roller compaction surface;
Step 4), brushing resin glue binding agent: the upper surface of damping layer 2 is adopted acetone cleaning, with rotary broom by the resin glue binding agent uniform application that configures in the upper surface of damping layer 2;
Step 5), paste carbon fiber board as carbon fiber restraint layer 1: by carbon fiber board uniform application in stickup position, and with the repeatedly roll extrusion of special cylinder, squeeze bubble removing, make the well-bonded damping sheet of resin glue binding agent and carbon fiber board; If carbon fiber restraint layer 1 is carbon cloth, then lay multi-storey up-down and translation successively according to the carbon cloth grain direction certain angle that staggers, resin glue binding agent is all used to bond between layers, with the repeatedly roll extrusion of special cylinder, squeeze bubble removing, make resin glue binding agent fully soak into carbon cloth, and ensure that cylinder roll extrusion can not destroy carbon cloth;
Step 6), solidification process: adopt cured 24 hours of inner die.
It is more than the explanation to lightweight Constrained Plates of the present invention.Because carbon fiber restraint layer 1 have employed carbon fiber light material, its elastic modelling quantity is better than steel, and specific strength is high, and its quality of condition of equivalent thickness is only about 1/5 of steel, therefore can reduce overall weight under the prerequisite ensureing binding effect, can be used in the damping vibration attenuation design to weight demands harshness.
Fig. 2 is the effectiveness in vibration suppression comparison diagram adopting the Constrained Plates of metallic plate in lightweight Constrained Plates of the present invention and prior art.In this contrast experiment, the aluminium sheet (area 400mm × 400mm) that thickness is 7mm is by vibration damping substrate 3, three kinds of damping sheet structures are respectively 4mm thickness damping sheet, 3mm thickness damping sheet+1mm steel plate, 4mm thickness damping sheet+0.5mm carbon fiber board, damping-constraining material is gained in weight and is respectively 1.275kg, 2.125kg, 1.585kg.As can be seen from the figure, the third damping sheet structure (i.e. structure of the present invention) comparatively the second damping sheet structure (the damping sheet structure usually adopted in prior art) quality is lighter, and damping effect promotes on the contrary to some extent.
In another comparative study, under distribution arbitrary excitation, three kinds of impedance bundary (seeing the following form 1) are adopted respectively to aluminium sheet (area 400mm × 400mm) flat board that thickness is 7mm, compare by all square response level spectrum of the speed of the whole flat board of FEM calculation numerical simulation, see Fig. 3.
Table 1 three kinds of impedance bundary thickness ratios
The existence due to restraining plate can be found out from this simulation result, all have very large lifting than without constrained layer damping plate low-frequency range effectiveness in vibration suppression with steel plate and carbon fiber board; And carbon fiber board can obtain and steel plate almost equal effectiveness in vibration suppression, adopt carbon fiber board than steel plate structure loss of weight amount very large (being 51%) simultaneously.
It should be noted last that, above embodiment is only in order to illustrate technical scheme of the present invention and unrestricted.Although with reference to embodiment to invention has been detailed description, those of ordinary skill in the art is to be understood that, modify to technical scheme of the present invention or equivalent replacement, do not depart from the spirit and scope of technical solution of the present invention, it all should be encompassed in the middle of right of the present invention.
