ABSTRACT:
A fiber lay-up apparatus and method includes one or more fiber sources from at least one fiber supply wherein a fiber may be fed under tension to provide a pre-stress to the fiber. The fiber lay-up apparatus may include a resin impregnator for impregnating a fiber with a resin. The fiber may be impregnated under pressure to reduce friction, to provide a motive force to move the fiber through the impregnator, or to enhance control over impregnation. The fiber may be shaped by a fiber shaping unit including one or more active or passive shaping members that provide enhanced control over the shape and placement of the fiber as the fiber leaves the fiber lay-up apparatus. A cutting element for cutting a fiber as it is being layed-up may be positioned proximal to the one or more shaping members, and may enable the fiber lay-up apparatus to end the lay-up of one fiber (or set of fibers) and begin the lay-up of a new fiber (or set of fibers) without delay. A UV or other curing element may be provided downstream from the cutting element. A splicing unit may be employed to detect when a fiber supply is exhausted, and may splice a trailing end of an exhausted fiber supply to a leading end of a new fiber supply to provide a continuous (or substantially continuous) fiber feed. The splicing unit may also splice at least one sensor into a fiber being fed from the at least one fiber supply to provide information about the fiber either before, during, or after the fiber is layed-up.
