Abstract:
A method and product comprising a composite elongate member (402), a channel (428), and a number of composite structures (431). The composite elongate member (402) has a side configured for attachment to a structure. The channel (428) is on the side of the composite elongate member (402) and extends along a length of the composite elongate member (402). The number of composite structures (431) is configured for placement in the channel (428) and to attach a portion of the side of the composite elongate member (402) to the structure (404). The number of composite structures (431) is configured to increase a capacity of the composite elongate member (402) to withstand forces that pull the composite elongate member (402) away from the structure (404).
Abstract:
A product comprising a composite elongate member ( 302 ), a channel ( 332 ), and a number of composite structures ( 304 ). The composite elongate member has a side configured for attachment to a surface of a structure. The channel is on the side and extends along a length of the composite elongate member. The number of composite structures is configured for placement in the channel and configured to attach a portion of the side of the composite elongate member to the structure. A composite structure in the number of composite structures comprises layers having different orientations selected to increase a capacity of the composite elongate member to withstand forces that pull the composite elongate member away from the structure.
Abstract:
Es wird ein Profilelement mit einem insbesondere aus Metall oder Kunststoff bestehenden lang gestreckten Profilkörper beschrieben. Der Profilkörper umfasst zumindest zwei separat ausgebildete Längsabschnitte, wobei jeder Längsabschnitt eine mäanderförmige Längskante sowie eine der mäanderförmigen Längskante gegenüberliegende geradlinige Längs- kante umfasst. Die Längsabschnitte sind über die geradlinigen Längskanten miteinander verbunden. Darüber hinaus wird ein solches Profilelement beschrieben, bei dem die Längsabschnitte separat oder einstückig ausgebildet sein können, wobei der Profilkörper einen im Wesentlichen U- oder V-förmigen Querschnitt mit zwei Profilschenkeln und einem die Pro- filschenkel verbindenden Profilsteg besitzt. Die Profilschenkel sind dabei durch die mäanderförmigen Längskanten umfassende umgebogenen Bereiche der Längsabschnitte gebildet und die jeweiligen Profilschenkel sind zumindest bereichsweise doppelwandig mit einer Aussenwand und einer zum Inneren des U- oder V-förmigen Querschnitts hin liegenden Innen- wand ausgebildet, wobei die mäanderförmigen Längskanten zumindest bereichsweise in den Innenwänden der doppelwandigen Profilschenkel verlaufen. Weiterhin wird ein Verfahren zum Herstellen solcher Profilelemente beschrieben.
Abstract:
본 발명은 상/하 면재 사이에 트러스 구조의 심재를 구비한 패널의 제조방법으로서, 상기 상/하 면재를 일정한 간격을 두고 평행하게 배치하는 단계; 상기 상/하 면재를 수평방향으로 상호 평행이동시킨 후 복수의 유연한 와이어로 상/하 면재에 수직하게 관통시켜 왕복 연결하는 단계를 수회 반복하여 수행하는 재봉단계; 및 상기 상/하 면재의 상대적 변위를 해소한 후 양 면재를 평행상태를 유지한 상태에서 수직한 방향으로 최대한 이격시킨 다음, 면재와 와이어를 고정하는 단계를 포함하여 구성되는 패널 제조방법에 대해 개시한다. 이 경우, 상기 재봉과정은 상/하 면재를 미리 평행하게 이동시킨 후 상/하 면재에 수직한 방향으로 와이어를 관통시켜 연결하는 방식으로 수행하되는 재봉과정은, 상/하 면재를 고정시킨 상태에서 상/하 면재에 경사진 방향으로 와이어를 관통시켜 재봉하는 방식으로도 수행될 수도 있다. 상기 방법에 따를 때, 심재를 3차원 트러스 형태로 형성함으로써 심재와 면재간 분리전항이 높고, 무게대비 압축, 전단, 굽힘 강도가 크고, 또한 경량이면서도 내부의 빈 공간을 활용할 수 있는 새로운 샌드위치 패널을 저비용 대량으로 제조하는 것이 가능하다.
Abstract:
A system for constructing a tank which is made up of a plurality of rectangular prism sections, which are hinged together on the back side to form a platform, having an end section hinged to a frame section, a cantilever frame extending from the end section, a counterbalance frame attached to said cantilever and extending parallel to the platform and opposed to the end section, with the end section and counterbalance frame being separated by a pair of saddle wheels mounted to the cantilever frame. At least one additional saddle wheel is mounted on a frame section for operation with saddle wheels on the cantilever to support the system on the tank wall and to move the platform within the tank wall as it is constructed. The hinge connections between the sections allow the platform to be adjusted to the arc of the internal wall of the tank under construction.
Abstract:
A repair process for a composite material panel (1) that forms part of the fuselage, the wings or the stabilizers of an aircraft, with the panel (1) having large dimensions and having irregular contours in some areas, comprising of edges (2) prone to damages occurring from the handling and assembly of said panel (1), characterized because it comprises of the following steps: a. Locating the damage (3) in the element (2) of the composite material panel (1); b. Sanding the area that comprises the damage (3) in an area larger than said damage 3, making a cut (9) in the panel (1), having said cut (9) being the same form as piece (7) that will serve to repair panel (1); c. Placement of the piece (7) in the cut (9), so that it is perfectly flush with the panel to be repaired (1); d. Attachment of the piece (7) to the composite material panel (1).
Abstract:
A contoured roller set and associated systems and methods are disclosed herein A male roller having a convex surface and a pair of female rollers each having a concave surface can receive a generally thin sheet of material and impart a doubly- curved shape to the sheet The convex and concave surfaces of the male and female rollers can have a radius of curvature chosen to match a radius of curvature of the sheet of material The rollers are positioned and shaped to urge the sheet between the female rollers to cause the sheet to curve toward the male roller.
