    • A system is provided for filling a gap between adjoining coplanar first and second sheet members mounted on an outer surface of a common substrate and having juxtaposed first and second edge surfaces. A permanent gap filler member of predetermined shape and size intended for eventual permanent reception in the gap is employed for partially filling the gap. A temporary gap filler tool which includes a substitute gap filler element having substantially the same predetermined size and shape of the permanent gap filler member, has an abutting surface for contiguous engagement with the first edge surface of the first sheet member when advanced to an attached position before the permanent gap filler member is mounted in the gap, a minor gap surface facing opposite said abutting surface, and means for releasably attaching the temporary gap filler tool to the first sheet member. A minor gap is thereby defined between the temporary gap filler element and the second edge surface of the second sheet member. Fairing material is initially laid down as an epoxy resin slurry in a minor gap resulting between the substitute gap filler element and the second edge surface of the second sheet member, then cured to hardened form having a substitute second edge surface contiguous with the minor gap surface of the substitute gap filler element. Thereafter, the temporary gap filler is removed from the gap and the permanent gap filler member is inserted and bonded to the common substrate resulting in the entire gap being filled.
    • 提供了一种用于填充安装在公共基板的外表面上并具有并置的第一和第二边缘表面的邻接的共面第一和第二片状部件之间的间隙的系统。 用于在间隙中最终永久接收的预定形状和尺寸的永久间隙填充构件用于部分填充间隙。 包括具有基本上相同的预定尺寸和形状的替代间隙填充元件的临时间隙填充工具具有邻接表面，用于当前进到附接位置时与第一片状构件的第一边缘表面连续接合 在永久性间隙填充构件安装在间隙中之前，与所述邻接表面相对的小间隙表面，以及用于将临时间隙填充工具可释放地附接到第一片构件的装置。 因此，临时间隙填充元件和第二片材的第二边缘表面之间限定了较小的间隙。 最初将整流材料作为环形树脂浆料在较小的间隙中放置，形成在替代间隙填充元件和第二片状构件的第二边缘表面之间，然后固化成硬化形式，其具有与次间隙表面相邻的替代的第二边缘表面 的替代间隙填充元件。 此后，从间隙中移除临时间隙填料，并将永久性间隙填充构件插入并结合到共用衬底，导致填充整个间隙。

    • An improved fuel tank for a lifting body re-entry vehicle having a particular external shape comprising four elongated lobes each having an external surface, each of the external surfaces having selected cylindrical and conical shapes, the lobes being selectively mateable to form a combined external configuration having a multiplicity of cylindrical and conical shapes conformable to at least a portion of the external shape of the vehicle. The cylindrical and conical shapes have variable radii at selected cross-sections thereof, such radii being selected for forming the external configuration. In a particular embodiment, the fuel tank has an initial portion, a midsection portion and a final portion and the cross-sectional shape of the initial portion of the fuel tank is that of two overlapping circles whose centers are positioned above one another, each of the circles being formed by two of the four lobes. In the midportion of the fuel tank, the cross-sectional shape is that of four overlapping circles whose centers are positioned to form a four-lobed closed arcuate figure. In the final portion of the fuel tank, the cross-sectional shape of the fuel tank is that of two overlapping circles whose centers are positioned aside one another, each of the circles being formed by two of the four lobes. When two such fuel tanks are placed side-by-side, the combined external surfaces closely approximate a large portion of the shape of the re-entry vehicle.

    • A method of forming composite sine wave spars from composite material. In accordance with the method, the sine wave spar is formed of web plies, filler plies, separator plies and cap plies. The edges of the web plies are cut to form a plurality of teeth having different geometric configurations. The web plies are first formed to the sine wave contours of a tool having the desired final part geometry. The teeth of the web plies are then folded over the edges of the tool to form a portion of the flanges of upper and lower U-shaped channels. The portions of the flanges of the U-shaped channels not covered by the teeth are formed using filler plies that intermesh with the teeth to form a layer of the flanges of the respective upper or lower U-shaped channel. The flanges are reinforced through the use of separator plies that are placed between the filler plies. The formed upper and lower U-shaped channels are joined together so that their respective flanges are located in line with each other. The triangular recesses between the flanges of the joined upper and lower U-shaped channels are filled with radius fillers having a triangular cross-section. Once the radius fillers are in place, cap plies are placed over the radius fillers and flanges to further reinforce the flanges. In the preferred embodiment, each web ply has eight different teeth configurations. The teeth are configured to fold over the edges of the sine wave contour and cover the edges of the sine wave contour in order to minimize overlapping and gaps between the folded over teeth.
    • 从复合材料形成复合正弦波的方法。 根据该方法，正弦波形梁由网状层，填料层，隔板层和盖层形成。 纤维网层的边缘被切割以形成具有不同几何构型的多个齿。 纸幅首先被形成为具有期望的最终零件几何形状的工具的正弦波轮廓。 然后将网状物层的齿折叠在工具的边缘上，以形成上部和下部U形通道的凸缘的一部分。 不被齿覆盖的U形通道的凸缘的部分使用与齿相互啮合以形成相应的上部或下部U形通道的凸缘层的填充层形成。 法兰通过使用放置在填料层之间的分离器层进行增强。 形成的上U形通道和下U形通道连接在一起，使得它们各自的凸缘彼此成一直线。 连接的上U形通道和下U形通道的凸缘之间的三角形凹槽填充有具有三角形横截面的半径填充物。 一旦半径填料就位，盖层放置在半径填料和凸缘上方，以进一步加强凸缘。 在优选实施例中，每个腹板层具有八个不同的齿构型。 齿构造成折叠正弦波轮廓的边缘并覆盖正弦波轮廓的边缘，以便最小化折叠齿之间的重叠和间隙。

    • A method for fabricating composite parts having improved pulloff strengths between portions of the composite part. In one embodiment, a sine wave spar is formed from two U-shaped channels having opposing flanges and a central web. The U-shaped channels are joined along the webs. The triangular gaps between the edges of the joined U-shaped channels are filled using a titanium radius filler that is configured to fit within the gaps. After the titanium radius filler is placed within the gaps, additional layers of composite material are placed over the titanium radius filler and the flanges of the U-shaped channels to form the caps of the I-beam. The resulting composite workpiece is then placed within appropriate tooling and cured within an autoclave. In other embodiments, the method of the invention is used to form spars, ribs, stringers, or bulkheads from composite materials.
    • 一种用于制造复合部件的部分之间具有改进的拉拔强度的复合部件的方法。 在一个实施例中，正弦波形梁由具有相对的凸缘和中心腹板的两个U形通道形成。 U形通道沿腹板连接。 连接的U形通道的边缘之间的三角形间隙使用被配置成配合在间隙内的钛半径填料来填充。 在将钛半径填料放置在间隙内之后，将复合材料的附加层放置在钛半径填料和U形通道的凸缘上以形成工字梁的盖。 然后将所得到的复合材料工件放置在适当的工具内并在高压釜内固化。 在其他实施例中，本发明的方法用于从复合材料形成翼梁，肋骨，桁条或隔板。
