Abstract

According to one embodiment, a Z-pinning patch comprises a pad for improving the binding strength of two or more combinations, and a plurality of Z-pins arranged on the pad, wherein the Z-pins can be separated from the pad, and a part of the Z-pins is exposed on the pad and the remaining parts of the Z-pins are inserted into the pad in the thickness direction. The pad can be made of rubber having a plate shape. The pad made of an elastic body and the patch having the Z-pins allow, in a combination molding step, the Z-pins of the patch to be insertedly fixed to a first member and the pad made of the elastic body to be separated from the upper part of the Z-pins, and allow a Z-pin fixing part bound to the pad protruding from the first member to be inserted into a second member through the separation of the pad and the Z-pins. Therefore, an integral binding method can be carried out.

Description

Z-피닝 패치 및 이를 이용한 결합체 일체접합 방법Z-Peening Patch and Combined Bonding Method Using the Same

More specifically, between the laminated surface of a composite laminate structure of aerospace and other transport machinery (automotive / high speed train / ship, etc.) that is manufactured by laminating a composite prepreg, or between two or more members, is connected. In order to improve the bonding strength of the present invention, a Z-pinning patch and method for contacting and connecting members by arranging Z-pins in the thickness direction of the members are disclosed.
항공우주 및 수송기구 구조부재 등의 경량화 구조물에 많이 사용되고 있는 섬유강화 결합재료는 대부분 일 방향 또는 직조된 프리프레그(prepreg)를 적층하고 열과 압력을 가하는 성형과정을 거침으로써 제작된다. 이렇게 적층 성형된 결합체 적층 구조물은 두께 방향으로는 별도의 강화재가 없기 때문에 외부의 충격 등에 의하여 쉽게 층과 층 사이가 분리되는 층간 분리 현상이 발생된다. 이 층간 분리는 구조물의 강도를 떨어뜨리기 때문에 이를 방지하기 위한 방법이 관련분야의 연구자들에 의하여 많이 연구되어 왔다. 즉, 결합체 적층 구조물의 취약한 층간 분리 특성을 보강하기 위하여 스티칭(Stitching), Z-피닝(Z-Pinning), 텍스타일(Textile), 고인성 수지(Toughened Matrix) 등의 방법에 대한 많은 연구들이 수행되어 왔다.Fibre-reinforced bonding materials, which are widely used in lightweight structures such as aerospace and transport structural members, are mostly manufactured by laminating unidirectional or woven prepregs and applying heat and pressure. Since the laminated laminate structure formed in this way does not have a separate reinforcing material in the thickness direction, an interlayer separation phenomenon in which layers are easily separated from each other due to an external impact or the like occurs. Since this delamination reduces the strength of the structure, methods for preventing this have been studied by researchers in the related field. In other words, many studies have been conducted on methods such as stitching, Z-pinning, textile, toughened matrix, etc. come.
결합체 적층 구조물의 층간 강성을 높이거나 두 결합체 적층 구조 부재간의 연결을 위한 연구들 중 Z-피닝(Z-pinning) 방법에 대한 연구는 비교적 최근에 시작된 연구 분야이다. Z-피닝에 대하여 알려진 연구내용을 간략히 살펴보면 다음과 같다.Among the studies for increasing the interlayer stiffness of the bonded laminate structure or connecting the two laminated laminate members, the Z-pinning method is a relatively recent research field. A brief review of known research on Z-pinning is as follows.
Z-피닝 방법의 최초 개념은 미국특허등록 제4,808,461호(1989. 2. 28)에서 볼 수 있다. 상기 문헌의 핵심 개념은, 폴리비닐 계열의 폼에 핀을 두께 방향으로 박아놓고, 상부에는 얇은 스테인레스 판을 부착하고 하부에는 이형재 필름을 부착한 소위 '강화 구조'라는 것을 성형 시 적층하기 위한 결합체의 상부에 위치하고 성형함으로써 성형과정에서 고온 고압에 의하여 프리폼이 붕괴되면서 핀이 적층판 내부로 박히게 하는 것이다. 성형이 완료되면 붕괴되어 압축된 프리폼의 잔재를 제거하고 그 두께만큼 돌출된 핀들을 물리력으로 부러뜨려 제거하면 적층 구조물 내부에는 적층 두께 방향으로 핀들이 박혀 남아있기 때문에 층간 분리 성능이 강화된다. 이러한 이전의 방법은, 결합체 적층 구조물에 핀을 박기 위하여 폼에 핀이 미리 박혀있고, 외부의 진동 하중이나 성형 압력에 의하여 폼이 압축 붕괴되면서 핀이 결합체 적층 구조물 안으로 박히는 특성을 갖는, 소위 '폼 구조('강화 구조'도 '폼 구조'의 일종으로 볼 수 있음)'를 매개체로 활용하고 있으며, 이 '폼 구조'를 그 방법의 특징으로 하고 있다. 그런데, 이러한 종래의 방법을 이용하여 '폼 구조'를 사용하는 경우에는 핀을 박고 나서 압축 붕괴된 폼을 인위적으로 제거하여야 하고, 핀의 돌출된 부분도 강제로 파단하여 제거하여야 하기 때문에 소재의 낭비 및 공정상의 비효율이 불가피하다. 또한 핀이 파단되어 제거된 위치에는 일부 흠집이 발생할 수도 있고, 핀의 파단 과정에서 핀과 주변 구조물의 강도에 악영향을 주게 되는 문제점이 있다.The initial concept of the Z-pinning method can be found in US Pat. No. 4,808,461 (February 28, 1989). The core concept of the document is that of a combination for laminating at the time of molding what is called a "reinforced structure" in which a pin is embedded in a polyvinyl foam in the thickness direction, a thin stainless plate is attached to the top, and a release film is attached to the bottom. The upper part is formed and molded, so that the preform collapses due to high temperature and high pressure in the forming process, causing the pin to be embedded into the laminate. When the molding is completed, the remnant of the deformed and compressed preform is removed and the pins protruding by the thickness are removed by physical force so that the interlayer separation performance is enhanced because the pins are embedded in the lamination thickness direction. This previous method is a so-called 'form, in which the pins are pre-embedded in the foam to pin the composite laminate, and the pins are pushed into the composite laminate while the foam is compressed and collapsed by external vibration loads or forming pressures. The structure ('reinforcement structure' can also be seen as a form of 'form structure') is used as a medium, and this 'form structure' is a feature of the method. However, in the case of using the 'foam structure' by using such a conventional method, the compression collapsed foam must be artificially removed after pinning, and the protruding part of the pin must be forcibly broken to remove material waste. And process inefficiency is inevitable. In addition, some scratches may occur at the location where the pin is broken, and the pin has a problem of adversely affecting the strength of the pin and the surrounding structure during the breaking of the pin.
뿐만 아니라, 이와 같이 폼 구조 또는 강화 구조를 사용하여 결합체 적층 구조물에 핀을 박는 방법은, 결합체 적층 구조물의 높이가 일정하지 않은 경우에 높이에 따라 핀이 박히는 깊이가 달라지므로, 상기 선행기술에 의하여 제작된 높이가 고르지 않은 결합체 적층 구조물은 위치문헌에 따라 층간 강성이 고르지 않게 된다는 큰 문제점이 있었다. 추가적으로, 높이가 일정하지 않은 결합체 적층 구조물에 Z-피닝하는 종래의 방법은 장비의 구성이 복잡하고 과정이 매우 난해하여 적용하기 매우 어려운 문제점 또한 있었다.In addition, the method of pinning the composite laminate structure using the foam structure or the reinforcement structure in this way, because the depth of the pin is changed depending on the height when the height of the composite laminate structure is not constant, according to the prior art The fabricated laminated structure having an uneven height has a big problem that the interlayer stiffness is uneven according to the position literature. In addition, the conventional method of Z-pinning in a laminate structure having a non-uniform height has a problem in that the configuration of the equipment is complicated and the process is very difficult to apply.
