Abstract: A composite braiding apparatus has a rotatable cantilever mandrel support 20 that is capable of supporting multiple mandrels 17a and 17b. The mandrels can be properly oriented to be braided without removing them from the mandrel support 20. Once the braiding operation has begun on one mandrel 17, subsequent mandrels can be mounted on the mandrel support 20 while braiding is taking place. Then, when a braiding operation is completed, the other mandrel 17 can be moved into proper position for braiding. The invention also allows one mandrel 17a (or 17b) to be braided while the opposite mandrel 17b (or 17a) that is not being braided can be worked on manually without stopping the braiding operation. In accordance with another embodiment of the invention, a braiding apparatus 10' has two braid ring assemblies 11a and 11b. Both braiding rings 12a and 12b are mounted at opposite ends of a guide track 26.

Abstract: An apparatus for molding hollow composite articles having a plurality of internal webs. A mandrel assembly apparatus includes slidable sidewall members, an inflatable pressure membrane surrounding the length of the slidable sidewall members and actuator means mounted on the interior of the sidewall members for lateral displacement thereof together with the inflatable membrane. Adjacent mandrel assemblies accurately position the internal webs of the composite article mechanically, while the inflatable membranes serve to compact the web laminates. The expandable sidewall members also prevent bridging or tearing of the pressure membrane associated with the formation of inner corner radii.
