    • A method for forming complexly shaped composite laminate assemblies. A pair of dry fiber preforms are placed on a tool with a thin film adhesive layer therebetween. A vacuum bag encloses the preforms and the adhesive layer. The preforms are heated to a temperature sufficient to cause the adhesive to become viscous and to wet several plys of each of the preforms. The preforms are then allowed to cool slightly before resin is infused via a vacuum source through each of the preforms to thoroughly wet each of the preforms. The resulting joint formed at the bond line of the two preforms is stronger than what would be formed simply by adhering two otherwise completely formed preforms together because the dry fiber preforms, in connection with the heating of the preforms, allow wetting of several plys of each of the preforms at the joint area, rather than just the surface ply of each preform.
    • 一种形成复杂复合层压组件的方法。 将一对干纤维预成型件放置在其上具有薄膜粘合剂层的工具上。 真空袋包围预成型件和粘合剂层。 将预成型件加热至足以使粘合剂粘稠并湿润每个预制件的多个层的温度。 然后将预成型坯稍微冷却,然后通过真空源通过每个预成型件输入树脂,以彻底润湿每个预成型件。 在两个预型件的结合线处形成的所形成的接头比通过将两个其它完全形成的预成型件粘合在一起形成的接头线更强,因为干纤维预成型件与预成型件的加热有关,允许润湿每个 的预型件,而不仅仅是每个预制件的表面层。
