    • A filament winding payoff unit and process for applying strands of adhesive impregnated filament material arranged into a gap-free band to a rotating mandrel. A plurality of side-by-side slightly overlapped impregnated filament strands are passed over bars between tines of combs for positioning when leaving the payoff head. The payoff head is positionable toward and away from the rotating mandrel to allow for mandrel longitudinal dimension changes while maintaining the payoff head roller in contact with the mandrel at a predetermined pressure thereagainst. The payoff head is also freely pivotable horizontally to maintain a proper angle of filament application to any changing mandrel longitudinal configuration.

    • Composite structures having a single continuous skin may be formed using automated fiber placement methods. These composite structures include frameless aircraft fuselage components offering an increased interior cabin width over conventional fuselage components. The composite structures may be constructed of multiple layers of fibers and other materials placed on a fiber placement tool that includes a mandrel body surrounded by a bladder or an integral bladder/caul sheet having expansion spaces created within the caul sheet section. Uncured composite structures may be created by placing fibers around the fiber placement tool in a plurality of discontinuous segments that are capable of moving or sliding in relation to each other so that the uncured composite structure is expandable from within. Fluid openings may be provided in the outer surface of the mandrel body for the application of vacuum and/or fluid pressure to secure the bladder to the mandrel body and to assist in the removal of the bladder from the mandrel body, respectively. Uncured composite structures may be sealed between the bladder and is clam shell molds. The uncured structures may be expanded against the inner surface of the molds by creating a vacuum between the bladder and molds.
    • 具有单一连续皮肤的复合结构可以使用自动纤维铺放方法形成。 这些复合结构包括无框架飞机机身部件,提供比常规机身部件增加的内部舱室宽度。 复合结构可以由多层纤维和放置在纤维铺放工具上的其它材料构成,该纤维布置工具包括被囊状物包围的心轴本体或具有在切片片段内产生的膨胀空间的整体囊/塞片。 未固化的复合结构可以通过将纤维围绕纤维布置工具放置在能够相对于彼此移动或滑动的多个不连续段中而形成,使得未固化的复合结构可从内部扩展。 流体开口可以设置在心轴体的外表面中,用于施加真空和/或流体压力,以将气囊固定到心轴体上,并且有助于分别从心轴本体移除气囊。 未固化的复合结构可以被密封在囊之间并且是蛤壳模具。 未固化的结构可以通过在气囊和模具之间产生真空而相对于模具的内表面扩张。

    • A composite structure for aircraft having features making it resistant to structural damage when subjected to lightning strikes. Fiber tow is wound over a rotating shaping surface which is a surface of revolution. Spaced bands of tow are laid down in a helical pattern with varying spaces between bands. Some bands are typically wound at an angle of about +45.degree.. By selectively winding in one direction and then the other, a "basketweave" pattern is obtained. Typically, the tow consists of high strength fibers in a thermosetting or thermoplastic resin matrix wound to a four layer thickness. When cured, the structure has high strength and low weight and is excellent for structures such as aircraft engine cowls. The basketweave pattern gives excellent resistance to peeling and delamination upon being struck by lightning, the types of damage which are likely to occur with the usual hoop or other continuous windings. The resistance to lightning strikes is further increased by winding one or more conductive filaments in a helical pattern, under tension, over the structure before the resin is cured. The conductive filaments serve to dissipate lightning energy over a large area and carry the charges away rapidly without being subject to peeling or separation from the composite structure surface.
    • 用于飞机的复合结构,具有使其在遭受雷击时抵抗结构损坏的特征。 纤维丝束缠绕在旋转表面上,旋转成形表面是旋转表面。 丝带的间隔带以带状之间的不同空间的螺旋图案放置。 一些条纹通常以约+45°的角度缠绕。 通过选择性地卷绕在一个方向上,然后另一个方向上,获得“网络”图案。 通常,丝束由缠绕成四层厚度的热固性或热塑性树脂基体中的高强度纤维组成。 固化时,该结构具有高强度和低重量,并且对于诸如飞机发动机罩的结构是优异的。 基于网络的图案,可以很好地抵抗由于雷击而导致的剥离和分层,这些类型的损伤可能会发生在通常的环形或其他连续绕组上。 通过在树脂固化之前将一种或多种导电细丝缠绕在结构上,在张力下以螺旋形式缠绕,从而进一步增加了对雷击的抵抗力。 导电丝用于在大面积上散发闪电能量,并迅速带走电荷,而不会从复合结构表面剥离或分离。
