    摘要： A hybrid composite-metal component is provided. The component includes an elongate inner metal piece, an outer metal piece disposed about at least a portion of the inner metal piece, and composite material disposed between the inner metal piece and the outer metal piece. The component may further include at least one of a seal and at least one fastener joining the inner metal piece and outer metal piece. Both the inner metal piece and the outer metal piece may include at least one tapered end. The tapered ends of both the inner metal piece and the outer metal piece each may include a double taper.

    摘要： A method of processing a composite structure in an autoclave involves producing a layup (10) with a low density honeycomb core (12) covered by resin impregnated composite face plies (14). The layup is sealed to a mold (18) under a vacuum bag (20). The layup is then cured in an autoclave under high temperatures and pressures. A vacuum is applied between the layup (10) and the vacuum bag (20) via a vacuum port (22), thus creating a pressure differential across the bag (20). This creates a compressive consolidating force on the composite face plies (14). Volatiles emitted during curing are drawn away through the vacuum port (22). The core (12) communicates with the autoclave by means of a pressurization tube (26) which penetrates the mold (18) and into the core (12), thus eliminating the pressure differential between the core (12) and the autoclave. Autoclave pressure is communicated throughout the entire core via perforations (13) in the honeycomb core (12).

    摘要翻译： 在高压釜中加工复合结构的方法包括用树脂浸渍的复合面层（14）覆盖的低密度蜂窝芯（12）制备叠层（10）。 叠层被密封在真空袋（20）下面的模具（18）上。 然后将叠层在高压釜中在高温和高压下固化。 通过真空端口（22）在叠层（10）和真空袋（20）之间施加真空，从而在袋（20）两端产生压差。 这在复合面层（14）上产生压缩固结力。 在固化过程中发出的挥发物通过真空口（22）被吸走。 核心（12）通过加压管（26）与高压釜连通，该加压管穿过模具（18）并进入芯部（12），从而消除了核心（12）和高压釜之间的压力差。 高压灭菌器压力通过蜂窝芯（12）中的穿孔（13）在整个芯体上传播。
