ABSTRACT:
An apparatus (10) for use in manufacturing a fibrous preform with a narrow channel flange includes a foraminous preform screen (12), a fiber nozzle (28) that blows a stream of chopped fibers onto the screen (12) and binder nozzles (32) that spray binder into the fiber stream. Air blown from air nozzles (30) helps guide the fibers and a ducted fan (26) helps draw and hold them onto the screen (12). The screen (12) is formed with a narrow channel flange (16) having a shape identical to the narrow channel flange of the fibrous preform to be manufactured. The screen's flange (16) has a channel floor (36) extending laterally outward from the screen's main body (14) and a channel outer wall (38) projecting perpendicularly away from the channel floor (36) toward the fiber nozzle (28). A hinge (40) connects the channel floor (36) to the channel outer wall (38). To allow the nozzles to deposit a more uniform layer (42) of fibers, the outer wall (38) is rotated outward to lie parallel with the channel floor (36). Following fiber deposition, the outer wall (38) is rotated back inward. After curing, the wall (38) is rotated outward again to facilitate preform (12) removal.
