Abstract
The utility model relates to the technical field of composite materials and particularly relates to an overdrawn-formed aramid honeycomb. The overdrawn-formed aramid honeycomb comprises a plurality of layers of aramid paper, wherein a spacing chamber is formed between every two layers of aramid paper, a plurality of glue tapes are uniformly arranged on the spacing chambers respectively along the transverse direction and consist of a plurality of glue tapes I and a plurality of glue tapes II, and the glue tapes I and the glue tapes II are of mutually-staggered arrangement; the glue tapes I are uniformly arranged on the spacing chambers of odd layers respectively along the transverse direction, and the glue tapes II are uniformly arranged on the spacing chambers of even layers respectively along the transverse direction; the cross section of internal cavities enclosed by the aramid paper and the glue tapes is rectangular. During use, problems in bent part forming technologies can be solved by using the overdrawn-formed aramid honeycomb, the laying performance in the aspect of transverse bending is relatively good, the regularity of formed hole grids is kept complete, and the original use performance in the aspect of longitudinal load bearing and mechanical properties is kept. The overdrawn-formed aramid honeycomb has the advantages of simple structure, reasonable arrangement, low manufacturing cost and the like.
Description
Technical field
The utility model relates to technical field of composite materials, particularly a kind of aramid fiber honeycomb of overstretching moulding.
Background technology
As shown in Figure 1, traditional regular hexagon honeycomb products, aspect composite sandwich plate utilization, has greater advantage, but aspect more complex-curved shaping, is being subject to larger restriction.Its reason is: regular hexagon honeycomb products (laterally) paving property covered aspect aspect bending can be subject to the impact of hole lattice shape, and inner side is squeezed, and outside is stretched, thereby destroys original hole lattice shape, and reduces the mechanical property of carrying and material.
Therefore be necessary the structure of existing aramid fiber honeycomb to carry out technological innovation further.
Utility model content
The purpose of this utility model is for the defect of prior art and deficiency, provides a kind of simple in structure, the aramid fiber honeycomb of overstretching moulding reasonable in design, easy to use.
For achieving the above object, the technical solution adopted in the utility model is:
The aramid fiber honeycomb of a kind of overstretching moulding described in the utility model, comprise some layers of aramid paper, between every two-layer aramid paper, be provided with a separate space, some interlayer separate spaces be laterally provided with some glue bars, described glue bar is made up of glue bar one and glue bar two, and glue bar one and glue bar two are the setting of mutually staggering; Between odd number layer separate space be laterally evenly provided with some glue bars one, between even numbers layer, separate space is laterally evenly provided with some glue bars two; The rectangular shape of inner chamber cross section that described aramid paper and glue bar surround.
Adopt after said structure, the utility model beneficial effect is: the aramid fiber honeycomb of a kind of overstretching moulding described in the utility model, comprise some layers of aramid paper, between every two-layer aramid paper, be provided with a separate space, some interlayer separate spaces be laterally provided with some glue bars, described glue bar is made up of glue bar one and glue bar two, and glue bar one and glue bar two are the setting of mutually staggering; Between odd number layer separate space be laterally evenly provided with some glue bars one, between even numbers layer, separate space is laterally evenly provided with some glue bars two; The rectangular shape of inner chamber cross section that described aramid paper and glue bar surround.In the time using the utility model, utilize the aramid fiber honeycomb of overstretching moulding can solve the forming technique at bending product, not only aspect transverse curvature, there is good paving and cover performance, hole lattice regularity after shaping remains intact, and aspect longitudinal load-bearing and mechanical property, is keeping original serviceability.The utlity model has simple in structurely, arrange rationally, the advantage such as cost of manufacture is low.
Brief description of the drawings
Fig. 1 is the structural representation before improving;
Fig. 2 is structural representation of the present utility model;
Description of reference numerals:
1, aramid paper; 2, glue bar one; 3, glue bar two.
Detailed description of the invention
Below in conjunction with accompanying drawing, the utility model is further described.
As shown in Figure 2, the aramid fiber honeycomb of a kind of overstretching moulding described in the utility model, comprise some layers of aramid paper 1, between every two-layer aramid paper 1, be provided with a separate space, some interlayer separate spaces be laterally provided with some glue bars, described glue bar is made up of glue bar 1 and glue bar 23, and glue bar 1 and glue bar 23 are the setting of mutually staggering; Between odd number layer separate space be laterally evenly provided with some glue bars 1, between even numbers layer, separate space is laterally evenly provided with some glue bars 23; The rectangular shape of inner chamber cross section that described aramid paper 1 and glue bar surround.
In the time using the utility model, utilize the aramid fiber honeycomb of overstretching moulding can solve the forming technique at bending product, not only aspect transverse curvature, there is good paving and cover performance, hole lattice regularity after shaping remains intact, and aspect longitudinal load-bearing and mechanical property, is keeping original serviceability.In addition, this is simple in structure, reasonable in design, low cost of manufacture.
The above is only preferred embodiments of the present utility model, and the equivalence of doing according to structure, feature and principle described in the utility model patent claim therefore all changes or modifies, and is included in the utility model patent claim.
