Description
Technical field
The present invention relates to the manufacture method of a kind of circular flexible honeycomb.
Background technology
In radome, a lot of structure is usually had to there is bigger curvature, conventional hexagonal shape honeycomb sandwich construction is still adopted in this deep camber situation, large deformation requirement in face in being difficult to opposing making and using, it is thus desirable to adopt a kind of moderate finite deformation that can produce in face can improve again the honeycomb sandwich construction of bearing capacity outside face simultaneously, create the flexible honeycomb sandwich of various version with this understanding, by designing version and the size of flexible honeycomb, realize large deformation in the face of honeycomb and require the outer high-mechanic requirement of dough-making powder.
Research shows, the deformability of honeycomb and bearing capacity depend on the geometry of honeycomb grid, arrangement mode and bond area. For difform cellular unit, the angle of its inclined side size and inclined side and straight flange is on the impact of its in-plane deformation substantially. With the structural plane internal strain ability of honeycomb for optimization aim, honeycomb shape and size are designed. The definition of reference material elastic modulus E, stretch modulus E in the equivalent face of definition honeycomb texture*Ratio for the pulling force on unit sectional area with the deformation in unit length. Choose honeycomb texture that in equivalent face, stretch modulus is less as flexible honeycomb structure. Research shows that in the equivalent face of the circular flexible honeycomb shown in Fig. 1, stretch modulus is the 41% of conventional hexagonal cell, the bond area of the circular honeycomb of same specification is 1.3 times of hexagonal cell, therefore in the in-plane deformation ability of circular honeycomb and face, adhesive strength is better than conventional hexagonal cell, is more suitable for honeycomb sandwich construction when deep camber, high intensity and uses.
The manufacture method of conventional hexagonal cell is that cellular material first builds up certain shape, forms again through gluing, rolling, solidification. Circular flexible honeycomb adopts the manufacture method of conventional hexagonal cell to make and has difficulties. It is, thus, sought for a kind of new manufacture method.
Summary of the invention
For the drawbacks described above existed in prior art, the invention provides the manufacture method of a kind of new circular flexible honeycomb.
The present invention is achieved by the following technical solution: the manufacture method of a kind of circular flexible honeycomb, described honeycomb is made up of several circular tangent orthogonal arrangement of cellular unit, cellular unit including two kinds of shapes, described cellular unit respectively circle is star-like with the four tangent compositions of circle, it is characterized in that: adopt honeycomb die and several unit pressing molds and several middle pressing molds to make, the base plate of described honeycomb die is arranged in sequence with the die cavity of the semi-circular shape that some tangent and with circular cellular unit shape is consistent, the shape of described unit pressing mold is identical with the shape of circular cellular unit, the shape of described middle pressing mold is identical with the shape of star-like cellular unit, it makes in accordance with the following steps: honeycomb paper is cut into the paper slip of one fixed width by (1) according to the honeycomb thickness of design, (2) uniform brushing releasing agent on the base plate of honeycomb die, (3) ground floor with described honeycomb paper strip double spread and is hung, (4) on the base plate of described honeycomb die, ground floor honeycomb paper is laid along the shape of described die cavity, (5) brushing releasing agent on all of unit pressing mold and middle pressing mold, (6) unit pressing mold is set in each described die cavity and forms ground floor unit pressing mold, with unit pressing mold, ground floor honeycomb paper is pushed down, and be provided above weight pressing plate at ground floor unit pressing mold and pushed down, (7) the unit pressing mold in ground floor unit pressing mold is taken out every row, (8) second layer with described honeycomb paper strip double spread and is hung, (9) after described weight pressing plate being removed, ground floor unit pressing mold lays second layer honeycomb paper along the shape of the die cavity after the shape of described unit pressing mold and taking-up pressing mold, then reset unit pressing mold in the die cavity after pressing mold second layer honeycomb paper is pushed down taking out, and be provided above weight pressing plate at unit pressing mold and pushed down, (10) third layer with described honeycomb paper strip double spread and is hung, (11) after being removed by described weight pressing plate, on ground floor unit pressing mold top, the shape along unit pressing mold lays third layer honeycomb paper, and embosses third layer honeycomb paper with intermediate pressure, then arranges weight pressing plate on middle pressing mold and is pushed down, (12) remaining honeycomb paper is laid on middle pressing mold top successively according to the step laying ground floor honeycomb paper, second layer honeycomb paper and third layer honeycomb paper, until last layer unit pressing mold is pushed down with weight pressing plate after laying, (13) it is heated cured, then each unit pressing mold and middle pressing mold is removed and formed circular flexible honeycomb.
In the present invention, after neighbouring two-layer honeycomb paper is completed, in the position of retrieval unit pressing mold, upper and lower two-layer honeycomb paper contacts, due to honeycomb paper double spread, therefore two-layer honeycomb paper is bonded together at two-layer honeycomb paper touching position up and down, it is bonded together in the tangent between adjacent circular cellular unit, and owing to scribbling releasing agent on unit pressing mold and middle pressing mold, do not bondd between unit pressing mold and middle pressing mold and upper and lower two-layer honeycomb paper, unit pressing mold and middle pressing mold can be drawn out of, namely unit pressing mold and middle pressing mold form circular flexible honeycomb after being drawn out of.
The manufacture method of the present invention is simple, practical and reliable, it may be achieved the making of honeycomb sandwich construction when deep camber, high intensity, can produce, by the method, the circular flexible honeycomb that conventional manufacture method is difficult to make. The circular flexible honeycomb texture produced by the method breaches the conventional on-deformable restriction of hexagonal cell, there is in-plane deformation ability and the crooked deformability of abundance, improve in vertical plane direction bearing capacity simultaneously, therefore solve the contradiction that deformable structure carries outside in-plane deformation dough-making powder.
