Ply transporting and compacting apparatus and method therefor

A ply transporting and compacting apparatus comprises a rigid frame, a top-layer sheet of flexible rubber material fastened to the frame, and a bottom-layer sheet of perforated flexible rubber material having openings. The apparatus also comprises a middle-layer sheet of flow media material disposed in a first plenum area that is defined between the top and bottom layer sheets. The apparatus further comprises a moving device coupled to the frame and arranged to lower the frame and sheets onto a composite ply at a trimming location to pick up the composite ply with a suction force when a vacuum is drawn in the first plenum area to create the suction force through the openings of the bottom-layer sheet.

Fiber width adjustment device, fiber width adjustment method and composite material molding method

According to one implementation, a fiber width adjustment device includes: a feeder and an adjuster. The feeder feeds a tape material in a length direction of the tape material. The tape material consists of fibers for a fiber reinforced resin after or before the fibers are impregnated with a resin. The adjuster has a path for the tape material. The path is formed by at least a bottom and a pair of wall surfaces. The interval of the wall surfaces decreased gradually. The width of the tape material which passed the path is changed by adjusting a part of the path. The tape material passes through the part of the path while contacting with the bottom and the wall surfaces.
