Described fiber reinforced rubber layer is by the rubber layer on upper and lower surface and is positioned at fibre reinforced materials in the middle of two rubber layers up and down and carries out the composite layer that forms behind the co-vulcanization.
The fibre reinforced materials of described layer of fibers or fiber reinforced rubber layer be with the vulcanization of rubber or with rubber combined before lamination coating after handling through resorcinol formaldehyde (RFL) resin surface.
The fiber reinforced rubber vibration isolator of the utility model is compared with existing vibration isolator, has following beneficial effect:
1, have certain bearing capacity:
Owing to the fiber reinforced rubber vibration isolator of the utility model is interlaced superimposed and constitute through vulcanizing bonding being integral by rubber layer and layer of fibers or fiber reinforced rubber layer, the effect of rubber in structure provides the ability of shearing and rotational deformation, reduce the natural frequency of vibrating isolation system, and reduce the influence colliding, impact; Layer of fibers or fiber reinforced rubber layer mainly produce constraint to the rubber layer lateral deformation in structure, make rubber be in three-dimensional stress state, and have very big vertical compression rigidity and vertical bearing capacity; Layer of fibers or fiber reinforced rubber layer do not influence the shear deformation of rubber layer again simultaneously, kept the intrinsic pliability of rubber, make it have the horizontal rigidity more much smaller than vertical rigidity, and prolong the level natural vibration period of oscillating body structure, thereby make vibration isolator possess the dual functions of vertical support and horizontal vibration isolating mechanism; Rubber in the vibration isolator also can adapt to the structure rotation that produces because of external force (wind-force in the building, the automobile mobile load in the bridge etc.) simultaneously, and therefore, this vibration isolator has certain bearing capacity, and the supporting (or bearing) that can be used as in the civil engineering is used.
2, damping capacity is good:
Because damping energy dissipation mechanism such as the viscoelasticity damping of the fiber of the vibration isolator of the utility model, interface damping, micro-damage sliding friction dampings, damping capacity is better than sheet metal; And in the fiber reinforced rubber vibration isolator that the utility model provides, there are a plurality of interfaces between layer of fibers inside, layer of fibers and the rubber, the total good damping property can be provided, thereby, the damping of the vibration isolator of the utility model very good (typical hysteresis loop is referring to Fig. 6).
3, good endurance:
Because the vibration isolator of the utility model is by layer of fibers or fiber reinforced rubber layer and rubber layer is staggered is formed by stacking; And be integral by the sulfuration bonding between this layer of fibers or fiber reinforced rubber layer and the rubber layer, can guarantee that both combinations in load bearing process are tight, no unsticking, therefore, the durability of this vibration isolator is better.
4, the vibration isolator performance has the designability of height:
Because this vibration isolator except the thickness of rubber layer can be regulated, can also be adjusted the principal direction of each unidirectional fiber layers in the layer of fibers according to the different needs to material all directions performance in-90 °~90 ° direction scopes; And the fiber volume fraction in fibrolaminar thickness, the layer of fibers, the fibrolaminar number of plies, laying sequential scheduling factor all can design adjustment as required; Therefore, the fiber reinforced rubber vibration isolator performance of the utility model has the designability of height.
5, corrosion resistance and good:
Because the fiber reinforced rubber vibration isolator of the utility model is made up of layer of fibers or fiber reinforced rubber layer and rubber layer, therefore, its corrosion resistance and good can be used in offshore structures such as the medium and small bridge in offshore area, beach plank road; Guarantee in longer service time, can not cause layer of fibers or fiber reinforced rubber layer and rubber layer unsticking lost strength because of corrosion.
