    摘要： An assemblage for bonding the skin of an airfoil to the core of the airfoil includes a hybrid caul plate assembly for covering the surface of the airfoil assembly which is exposed to bonding pressure. The hybrid caul plate includes a central elastomeric component and peripheral semi-rigid metal components. The semi-rigid metal components are formed from a steel sinusoidal mesh and are axially elongated. The mesh is flexible in the direction of elongation, but are rigid in the transverse direction. The peripheral semi-rigid caul componnents will thus closely conform to the contours of the core in the axial direction, and will, at the same time, provide support for the edges of the core so that the core edges will not be crushed or deformed by bonding pressure applied to the assemblage during the skin-to-core bonding process. The result of using the hybrid caul plate assembly is an improved skin-to-core bond wherein bridging or voids in the bond line at the periphery of the airfoil are avoided.

    摘要： Uncured elastomeric sheet material (42) is built up on the outer surface of a production article (36) constructed from composite materials. A vacuum bag system (20, 24, 26, 30, 32) is used for holding the uncured elastomer member (60) against the composite article (36) while the elastomer member (60) is being cured under heat and pressure. Such curing causes the elastomer member (60) to shrink. The elastomer member (60) is then resized by cutting it into sections (66). The sections (66) are placed back on the composite article (36) and each is positioned on such article (36) at a location best conforming to it in shape. This leaves gaps (68) between the sections (66). Additional uncured elastomer (70) is applied to fill the gaps (68) and bridge across the gaps (68), to in that manner splice the sections (66) together. A vacuum bag (20, 24, 26, 30, 32) is again applied and the bag assembly (20, 24, 26, 30, 32 ) is again cured under heat and pressure, to cure the additional elastomer material (70). The elastomer member (60") formed in this manner substantially conforms in size and shape to the production composite article (36) and can be used as a pressure pad in the manufacture of additional articles (36) of the composite material.
