본 발명은 하니컴 코아에 관한 것이다. 보다 상세하게는 포밍(forming)시 안티클래스틱 곡선(anticlastic curvature)이 발생하지 않은 하니컴 코아 및 하니컴 코아용 금형 및 상기 하니컴 코아 제조방법에 관한 것이다.The present invention relates to a honeycomb core. More specifically, the present invention relates to a mold for honeycomb cores and honeycomb cores, and a method of manufacturing the honeycomb cores, which do not generate an anticlastic curvature during forming.

하니컴 코아는 중량감소 및 강성증가를 위해 주로 사용된다. 하니컴 코아는 원하는 특성에 따라 여러가지 형태의 단면을 가진 셀의 집합 구조물을 말하나, 통상적으로는 도1에 도시된 형태의 가장 안정적이고 경제적이며 가벼우면서도 고강도를 발휘하는 육각셀 하니컴코아가 가장 많이 이용된다.Honeycomb cores are mainly used for weight reduction and stiffness increase. Honeycomb core refers to a collection structure of cells having various shapes of cross-sections according to desired characteristics. However, the most stable, economical, light and high strength hexagonal honeycomb core of the type shown in FIG. 1 is most commonly used. .

이러한 육각셀 하니컴 코아의 제조방법에는 익스펜션(expansion) 제조방법, 커러게이션(corrugation) 제조방법, 몰딩 또는 압출등을 들 수 있다. 도2는 익스펜션 제조방법을 도시하고 있는데 이를 참고하면, 소정크기의 시트(10)의 소정부에 접착제(11)를 도포하여 다수개의 시트의 접착제(11)가 도포된 부분이 지그제그로 위치토록 적층한 후 적층된 시트를 일정한 크기로 인장하면, 접착제(11)가 도포된 부분은 시트(10)끼리 부착되고, 접착제(11)가 도포되지 않은 부분은 시트와 시트가 이격되어 벌집모양의 하니컴코아가 형성되며, 상기 코아의 상하측에 표재(미도시)를 부착함으로써 하니컴 판넬이 완성된다. 한편, 도3은 커러게이션 제조방법을 도시하고 있는데 이를 참고하면, 커러게이션 롤(20) 사이로 시트(21)를 통과시켜, 시트(21)에 커러게이션을 형성한 후, 상기 시트(21)를 적층하여 접촉부분에 접착제를 도포하면 하니컴코아가 형성되며, 상기 코아의 상하측에 표재를 부착하여 하니컴 판넬이 완성된다. 몰딩 및 압출에 의한 하니컴체 제조방법은 하니컴 코아를 직접 몰딩 또는 압출에 의해 제조한 후, 표재의 부착에 의해 하니컴체가 제조된다.Examples of such hexagonal cell honeycomb core manufacturing methods include expansion manufacturing methods, corrugation manufacturing methods, molding or extrusion. 2 illustrates an expansion manufacturing method. Referring to FIG. 2, an adhesive 11 is applied to a predetermined portion of a sheet 10 of a predetermined size so that a portion of the adhesive 11 of a plurality of sheets is positioned in a zigzag. When the laminated sheets are stretched to a certain size after lamination, the portions to which the adhesive 11 is applied are attached to the sheets 10, and the portions to which the adhesive 11 is not applied are spaced apart from the sheets to form a honeycomb. A honeycomb core is formed, and the honeycomb panel is completed by attaching a top surface (not shown) to the top and bottom sides of the core. On the other hand, Figure 3 shows a method of manufacturing a coagulation, referring to this, passing the sheet 21 between the corollation roll 20, to form a coagulation in the sheet 21, and then to the sheet 21 When the adhesive is applied to the contact portion by lamination, a honeycomb core is formed, and a honeycomb panel is completed by attaching a surface material to the upper and lower sides of the core. In the method for manufacturing a honeycomb body by molding and extrusion, the honeycomb core is manufactured by direct molding or extrusion, and then the honeycomb body is manufactured by adhesion of the surface material.

한편, 이렇게 제조된 하니컴코아는 포밍(벤딩등을 통한 다양한 형상창출)시 도 4에 도시된 안티클래스틱 곡선을 발생시킨다. 육각셀 하니컴 코아의 경우 셀의상,하면은 다른 셀의 면에 접착되어 있다. 따라서 도4와 같이 코아의 일측을 벤딩할 때, 상기 일측에 가해진 벤딩력은 셀 각각의 접착면에 순차적으로 전위되어 타측까지 영향을 미치게 된다. 이때 타측에 위치한 셀의 각변은 하나의 직선으로 구성되므로, 전위된 벤딩력을 수용할 인장여유가 없게 된다. 결국 타측부위는 벤딩력이 가해진 방향의 역방향으로 반발되게 되며, 면이 방향을 달리하여 굽혀지는 안티클래스틱 곡선 현상을 발생시키게 된다.On the other hand, the honeycomb core thus produced generates an anti-classtic curve shown in FIG. 4 when forming (forming various shapes through bending, etc.). In the case of the hexagonal cell honeycomb core, the upper and lower surfaces of the cell are bonded to the surface of another cell. Therefore, when bending one side of the core as shown in Figure 4, the bending force applied to the one side is sequentially displaced on the adhesive surface of each cell affects the other side. At this time, since each side of the cell located on the other side is composed of one straight line, there is no tension margin to accommodate the displaced bending force. Eventually, the other side will be repulsed in the opposite direction to the bending force, and the surface will be bent in different directions to generate an anti-class curve.

이와 같이 안티클래스틱 곡선은 기계적 힘을 빌려 방지할 수 있다. 미국특허제6,272,897호는 strectch wrap machine을 이용하며, 미국특허 제6,372,322호는 stamping 방법과 유사한 방법을 이용하여 안티클래스틱 곡선이 형성되는 것을 강제적으로 억제시키는 방안을 개시하고 있다. 그러나, 상기 방안들에 의하면, 벤딩부에 잔류응력을 생겨 내구성이나 에너지 흡수력 등 기계적 특성을 나쁘게 한다. 또한 벤딩부에는 주름이 형성되거나, 스프링 백 현상이 일어나거나 크랙 및 파단등이 일어난다.As such, the anticlass curve can be prevented by borrowing mechanical force. US Pat. No. 6,272,897 uses a strectch wrap machine and US Pat. No. 6,372,322 discloses a method of forcibly suppressing the formation of an anticlassic curve using a method similar to the stamping method. However, according to the above methods, residual stresses are generated in the bending part to deteriorate mechanical characteristics such as durability and energy absorption. In addition, the bending portion is formed wrinkles, spring back phenomenon occurs or cracks and breaks occur.

한편, 안티클래스틱 곡선은 도 5에 도시된 플렉스셀 코아를 제작함으로써 방지할 수 있다. 플렉스셀 코아는 셀의 각 변이 물결형상(Z)을 이루고 있다. 플렉스셀 코아는, 도1에 도시된 셀 각변이 하나의 직선으로 구성된 육각셀 코아와는 달리, 물결형상(Z)의 셀 모양상 전위된 벤딩력을 수용할 만큼의 인장여유가 있기 때문에 안티클래스틱 곡선은 생기지 않게 된다. 그러나, 플렉스 코아는 셀 변에 물결형상(Z)을 구비해야 하므로, 육각 하니컴 코아보다 가격이 2 내지 5배 정도 비싸 실용성이 떨어진다.On the other hand, the anticlassic curve can be prevented by manufacturing the flexcell core shown in FIG. In the flexcell core, each side of the cell forms a wave shape (Z). In the flexcell core, unlike the hexagonal cell core of which each side of the cell shown in FIG. 1 is composed of one straight line, the flexcell core has a tension margin sufficient to accommodate the cell-shaped displaced bending force in the wavy shape Z. Tick curves do not occur. However, since the flex core must have a wavy shape (Z) on the side of the cell, the price is about 2 to 5 times more expensive than the hexagonal honeycomb core and is inferior in practicality.

한편 육각셀 코아든 플렉스셀 코아든, 각 셀의 상하변은 인접셀의 상하변에 접착되기 때문에 그 인접면에 대해 두께가 2배가 된다(접착면 중복현상). 따라서 강성이 불균일해지고 두께가 상대적으로 얇은 인접면으로 응력이 집중되는 현상이 일어나며, 접착면 전체에 접착제를 도포해야 하므로 접착제 소모량이 많다On the other hand, the hexagonal cell core or the flex cell core, the upper and lower sides of each cell is bonded to the upper and lower sides of the adjacent cell, so the thickness is doubled with respect to the adjacent surface (adhesive surface overlap). Therefore, the stiffness becomes uneven and the stress is concentrated on the adjacent surface where the thickness is relatively thin, and the adhesive consumption is high because the adhesive must be applied to the entire adhesive surface.

이하, 첨부도면을 참고하여 본 발명을 상세히 설명한다.Hereinafter, the present invention will be described in detail with reference to the accompanying drawings.

본 발명에 따른 하니컴 코아는 안티클래스틱 곡선이 발생하지 않아 포밍이 용이하며, 셀의 단면형태는 가장 안정적이고 고강도인 육각셀(A)과 성(星)형셀(B)을 구비한 하니컴 코아로, 제1시트(101)와 제2시트(102)를 순차적으로 적층함으로써 제조될 수 있다.The honeycomb core according to the present invention is easy to form because no anticlass curve occurs, and the cross-sectional shape of the cell is the honeycomb core having a hexagonal cell (A) and a star-shaped cell (B), which are the most stable and high strength. The first sheet 101 and the second sheet 102 may be manufactured by sequentially laminating the same.

도6에 도시된 바와 같이, 제1시트(101)는 연속된형상의 단면으로 마련되고, 제2시트(102)는 연속된형상의 단면으로 마련된다. 여기서, 제2시트(102)는 제1시트를 역전시켜 놓은 형상으로써, 편의를 위해 본 명세서에는 제2시트(102)라 칭하기로 한다.As shown in Figure 6, the first sheet 101 is continuous The cross section of the shape is provided, the second sheet 102 is continuous It is provided with a cross section of the shape. Here, the second sheet 102 is a shape in which the first sheet is reversed, and for convenience, the second sheet 102 will be referred to as a second sheet 102.

한편, 상기 시트는 알루미늄, 스테인레스, 구리등 건축 내, 외장재나 항공기, 자동차등에서 통상적으로 사용되는 재질일 수 있으며, 종이, 나무 또는 플라스틱이어도 무방하다.On the other hand, the sheet may be a material commonly used in construction, such as aluminum, stainless steel, copper, exterior materials, aircraft, automobiles, may be paper, wood or plastic.

제1시트(101)와 제2시트(102)는 도7에 도시된 것처럼 순차적으로 적층되며,제1시트(101)와 제2시트(102)의 접촉부위는 재질이나 용도에 따라 에폭시등의 접착제나 레이저 용접, 스폿 용접 또는 마찰용접등으로 접합된다.The first sheet 101 and the second sheet 102 are sequentially stacked as shown in FIG. 7, and contact portions of the first sheet 101 and the second sheet 102 are made of epoxy or the like according to a material or a purpose. Bonded by adhesive, laser welding, spot welding or friction welding.

이와 같이 제조된 하니컴 코아는 도8에 도시된 바와 같이, 별형상()의 성형셀(B)이 배치되고, 성형셀 외주부에는 6개의 육각셀(A)이 배치되고, 상기육각셀(A)의 외주부에는 다시 성형셀(B)이 배치되는 형식의 코아로 마련된다.The honeycomb core manufactured as described above has a star shape as shown in FIG. ) Is formed into a core of a type in which a forming cell (B) is arranged, six hexagonal cells (A) are arranged on an outer circumferential portion of the forming cell, and a forming cell (B) is arranged again on the outer circumferential portion of the hexagonal cell (A). .

이 때, 성형셀(B)과 육각셀(A)의 접착점은 단면상으로 한점으로 표현되며(도 7참조), 사시상으로는 선으로 표현된다(도 8참조). 또한, 성형셀(B)의 외부꼭지점과 상기 외부꼭지점에 인접하는 외부꼭지점 사이의 변(이하, '내변'이라 함: Z`)은 하나의 직선이 아닌 두개의 직선으로 구성된다.At this time, the bonding point of the shaping cell (B) and the hexagonal cell (A) is represented by one point in cross section (see FIG. 7), and is represented by a line in perspective view (FIG. 8). In addition, the side (hereinafter, referred to as 'inner side': Z`) between the outer vertex of the forming cell B and the outer vertex adjacent to the outer vertex is composed of two straight lines instead of one straight line.

이러한 형상을 지닌 본 발명에 따른 하니컴 코아는 도 9에 도시된 바와 같이 포밍시 안티클래스틱 곡선을 유발시키지 않게 된다.The honeycomb core according to the present invention having such a shape does not cause an anticlassic curve when forming as shown in FIG. 9.

이를 상세히 설명하면, 도1에 도시된 종래의 육각셀 코아는 육각셀로만 이루어져 있기 때문에 셀과 셀 접착부는 단면상으로 선, 사시상으로는 면으로 표현되며, 셀의 각변은 하나의 직선으로 구성된다. 따라서, 어느 한셀에 작용하는 힘은 인접셀과의 접촉면을 통해 순차적으로 타셀로 전위되어 코아전체에 영향을 미치게 되며, 하나의 직선으로 구성된 변을 가진 셀은 전위된 힘을 수용할 인장여유가 없게 된다. 따라서 포밍시 도4와 같은 안티클래스틱 곡선을 발생시키게 된다.In detail, since the conventional hexagonal cell core shown in FIG. 1 is composed of only hexagonal cells, the cell and the cell adhesive part are represented by a line in cross section and a plane in perspective, and each side of the cell is composed of one straight line. Therefore, the force acting on any one cell is sequentially displaced to the other cell through the contact surface with the adjacent cell and affects the whole core, and the cell having one straight line has no tension margin for receiving the displaced force. do. Therefore, when forming, an anticlassic curve as shown in FIG. 4 is generated.

그러나, 본 발명에 따른 코아는 성형셀(B)과 육각셀(A)의 접착부가 단면상으로는 점, 사시상으로는 선으로 표현되므로(선접착) 어느 한 셀에 작용하는 힘이 인접셀에 전위되기가 종래의 육각셀보다 어렵고, 성형셀(B)의 내변(Z`)은 2개의 직선으로 구성되므로, 도5에 도시된 플렉스셀 코아처럼 전위된 힘을 수용할 수 있는 인장여유가 생겨, 안티클래스틱 곡선은 발생되지 않게 된다. 따라서, 본 발명에 따른 코아를 포밍할 경우에는 안티클래스틱 곡선을 강제적으로 방지하기 위한 별도의 기계적 힘을 요구하지 않는다.However, in the core according to the present invention, the bonding portion of the shaping cell (B) and the hexagonal cell (A) is represented by a point in cross section and a line in a perspective view (preliminary bonding). It is more difficult than the conventional hexagonal cell, and since the inner edge Z` of the forming cell B is composed of two straight lines, a tension margin can be obtained to accommodate the displaced force as in the flexcell core shown in FIG. Tick curves are not generated. Therefore, when forming the core according to the present invention does not require a separate mechanical force to forcibly prevent the anticlassic curve.

또한, 본 발명에 따른 코아는, 면접착하는 종래의 육각셀 코아나 플렉스셀 코아와는 달리 선접착하기 때문에, 접착면 중복현상이 생기지 않는다. 따라서, 셀 전체적으로 강성이 균일해지며, 응력집중이 방지된다. 또한 접착부위의 감소로 접착제가 절약되며, 용접접착의 경우에는 용접이 용이해진다는 효과가 있다.In addition, since the core according to the present invention is pre-bonded unlike conventional hexagonal cell cores or flex cell cores that are face-bonded, no overlapping phenomenon occurs. Therefore, the rigidity is uniform throughout the cell, and stress concentration is prevented. In addition, the adhesive is saved by the reduction of the adhesive portion, and in the case of welding adhesion, there is an effect that the welding becomes easy.

이처럼, 본 발명은 코아 시트 접착에 있어, 종래의 면접착에서 선접착을 채용한 새로운 방식의 시도로서, 성형셀 형상 변경을 통한 선접착을 이루는 다양한 하니컴 코아 역시 본 발명의 사상범위에 속함은 당업자에게 자명하다.As described above, the present invention is an attempt of a new method employing pre-adhesion in the conventional face bonding in the core sheet adhesion, and various honeycomb cores for achieving pre-adhesion by changing the shape of the molding cell are also within the scope of the present invention. Self-explanatory

본 발명에 따른 시트(101, 102)는 도10에 도시된 금형을 이용한 압출, 인발, 압출 등 통상의 공지된 공정을 통해 제조된다.Sheets 101 and 102 according to the present invention are manufactured through a conventional known process such as extrusion, drawing, extrusion using a mold shown in FIG.

도10은 본 발명에 따른 시트(101, 102)를 제조하기 위한 상형틀(111)과 하형틀(112)을 도시하고 있다. 상형틀(111)은 연속된형상의 성형면을 지니고, 하형틀(112)은 상기 상형틀(111)에 대응하는 형상의 성형면을 지니고 있다. 따라서, 셀을 만들고자 하는 시트를 상기 상하금형을 통해 압연, 인발 또는 압출등을 하게 되면, 본 발명에 따른 제1시트(101) 및 제2시트(102)가 제조된다.10 shows the upper mold 111 and the lower mold 112 for manufacturing the sheets 101, 102 according to the present invention. Pictograph 111 is continuous It has a shaping surface of a shape, the lower mold 112 has a shaping surface of a shape corresponding to the upper mold 111. Accordingly, when the sheet to be made of the cell is rolled, drawn, or extruded through the upper and lower molds, the first sheet 101 and the second sheet 102 according to the present invention are manufactured.

한편, 도 11에 도시된 바와 같이, 셀을 만들고자 하는 시트가 강성이 높은 재질인 경우에는 복수개로 배치된 상하금형을 통해 제조될 수 있다. 이때 각 금형의 형상은 단계별로 시트 단면 형상이 달라지도록 하며, 최종 금형은 시트 단면의 변형에 대한 복원을 고려하여 최종 시트 단면 형상 보다 좀 더 포밍을 갖도록 하는 것이 바람직하다. 그러나 강성이 낮아 변형이 쉬운 재질의 경우에는 도10에 도시된 것 같이 하나의 금형만을 사용할 수 있다.On the other hand, as shown in Figure 11, when the sheet to make the cell is a material of high rigidity can be manufactured through a plurality of upper and lower molds arranged in plurality. At this time, the shape of each mold is to change the sheet cross-sectional shape step by step, it is preferable that the final mold has a more forming than the final sheet cross-sectional shape in consideration of the restoration to the deformation of the sheet cross-section. However, in the case of a material having low rigidity and easy deformation, only one mold may be used as shown in FIG. 10.

본 발명의 일실시예로 제1시트와 제2시트를 순차적으로 적층한 후, 접촉부위에 접착제를 도포하거나 용접하여 제작되는 하니컴 코아에 대해 지금까지 서술하였으나, 본 발명에 따른 하니콤 코아는 별형상의 성형셀이 배치되고, 상기 성형셀 외주부에는 6개의 육각셀이 배치되고, 상기 육각셀의 외주부에는 다시 성형셀이 배치되는 격자구조의 하니컴 코아로서 일체로 제조될 수 있다.In one embodiment of the present invention after stacking the first sheet and the second sheet sequentially, the honeycomb core produced by applying or welding the adhesive to the contact point, but the honeycomb core according to the present invention has been described so far Shaped molding cells are arranged, six hexagonal cells are arranged on the outer peripheral portion of the molding cell, the molding cell can be manufactured integrally as a honeycomb core of the lattice structure in which the molding cells are arranged again.

그 하나의 예시로, 도 12에 도시된 바와 같은 금형을 사용하여, 본 발명에 따른 하니컴 코아를 일체로 제작할 수 있다. 상기 실시예의 금형은 성(星)형셀판(B`)이 배치되고, 상기 성형셀판(B`) 외주부에는 6개의 육각셀판(A`)이 배치되고, 상기 육각셀판(A`)의 외주부에는 다시 성형셀(B`)이 배치되는 격자구조로, 상기 성형셀판(B`)과 육각셀판(A`)의 사이의 공간에는 본 발명에 따른 하니컴 코아 형상의 블랭크(C)가 형성되어, 본 발명에 따른 하니콤 코아를 일체로 형성할 수 있다.As one example, a honeycomb core according to the present invention can be integrally manufactured using a mold as shown in FIG. 12. In the mold of the embodiment, a star-shaped cell plate B` is disposed, six hexagonal cell plates A` are disposed on an outer circumference of the molded cell plate B`, and an outer peripheral portion of the hexagonal cell plate A` is disposed. In the lattice structure in which the shaping cell B` is disposed again, a honeycomb core-shaped blank C according to the present invention is formed in the space between the shaping cell plate B` and the hexagonal cell plate A`. The honeycomb core according to the invention can be integrally formed.

이하에서는 본 발명에 따른 하니컴 코아를 이용한 하니컴 판넬을 개시하고자 한다.Hereinafter will be described a honeycomb panel using a honeycomb core according to the present invention.

도13을 참고하면, 본 발명에 따른 하니컴코아의 상 하측에는 접착제(150)와 표재(160)가 각각 병렬배치하여, 이들을 압착한 후 접착제(150)를 큐어링(curing)하면 평판형 하니컴 판넬이 완성된다. 또한 도14에 도시된 바와 같이, 원하는 형상을 지닌 형틀(200)을 마련하면, 상기 형틀(200)의 형상에 대응하는 하니컴 판넬을 제작할 수 있다. 본 발명에 따른 하니컴 코아는 포밍시 안티클래스틱 곡선이 발생하지 않기 때문에, 상기 형틀은 다양한 형상을 창출하는데 있어 형틀에 불과할 뿐안티클래스틱 곡선을 방지하는 역할을 수행하지는 않는다.Referring to Figure 13, the upper and lower sides of the honeycomb core according to the present invention, the adhesive 150 and the surface material 160 are placed in parallel, respectively, after pressing them to cure the adhesive (curing) 150 flat honeycomb panel This is done. In addition, as shown in Figure 14, by providing a mold 200 having a desired shape, it is possible to manufacture a honeycomb panel corresponding to the shape of the mold 200. Since the honeycomb core according to the present invention does not generate an anticlass curve when forming, the template is merely a template for creating various shapes and does not play a role of preventing the anticlass curve.

또한, 본 발명에 따른 하니컴 판넬은 접착제를 사용하지 않을 수도 있다. 예를 들면, 하니컴 코아와 표재(160)가 용접에 접합한 재료일 경우에는 마찰용접, 레이저 또는 스폿 용접을 행함으로써 하니컴 판넬이 완성된다. 접착제가 열화될 수 있는 고온(80도 이상)영역이나 접작제의 낮은 허용전단응력상 큰 강도가 요구되는 구조물에서는 본 실시예가 아주 유용하다.In addition, the honeycomb panel according to the present invention may not use an adhesive. For example, when the honeycomb core and the surface material 160 are materials joined to the welding, the honeycomb panel is completed by performing friction welding, laser or spot welding. This embodiment is very useful in high temperature (more than 80 degrees) areas where the adhesive may deteriorate or in structures where large strength is required due to the low permissible shear stress of the adhesive.

한편, 본 발명에 따른 하니컴 판넬을 수회 반복하여 적층함으로써 다수의 코아와 접착제 및/또는 표재가 적층된 필요한 두께를 가지는 다층 하니컴 판넬 제작도 가능하다.On the other hand, by repeatedly stacking the honeycomb panel according to the present invention it is also possible to manufacture a multi-layer honeycomb panel having a required thickness of a plurality of cores and adhesives and / or the surface material is laminated.

상술한 바와 같이 본 발명에 의하면, 포밍시 안티클래스틱 곡선이 생기지 않기 때문에 포밍이 용이하며 스프링 백 영향이 거의 없으며 잔류 응력이 생기지 않는다. 또한 안티클래스틱 곡선을 강제적으로 방지하기 위한 기구가 필요하지 때문에 경제적이다. 또한, 선접착을 통한 접착면 중복현상을 제거하였기 때문에 단위면적당 무게감소가 이루어져 하니컴 판넬의 기본성능인 경량성을 극대화 할 수 있으며, 접착제를 절약할 수 있고, 코아가 구조물로서 균일한 성능을 가지는 효과가 있다.As described above, according to the present invention, since the anticlass curve is not generated during forming, the forming is easy, there is almost no spring back effect, and no residual stress is generated. It is also economical because no mechanism is needed to forcibly prevent anticlassic curves. In addition, since the overlapping phenomenon of adhesive surface is eliminated through pre-gluing, the weight per unit area is reduced to maximize the lightness, which is the basic performance of honeycomb panel, saving adhesive, and core having uniform performance as a structure. It works.

또한, 본 발명에 따른 하니콤 판넬에 의하면, 저온환경에서는 접착제방식을, 고온환경에서는 용접방식을 사용하도록 하여, 이용가능한 산업분야를 확대시킨 효과가 있다. 하니컴 판넬을 수회 반복하여 적층함으로써 다수의 코아와 접착제 및/또는 표재가 적층된 필요한 두께를 가지는 다층 하니컴 판넬 제작도 가능하여 고 강성 및 고 충격흡수력이 요구되는 물성을 충촉시키는 효과가 있다.In addition, according to the honeycomb panel according to the present invention, by using the adhesive method in the low temperature environment, the welding method in the high temperature environment, there is an effect of expanding the available industrial field. By repeatedly stacking the honeycomb panel several times, it is possible to manufacture a multilayer honeycomb panel having a required thickness in which a plurality of cores, adhesives and / or surface materials are stacked, thereby filling the physical properties requiring high rigidity and high impact absorption.
