Abstract: 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.

Abstract: A composite manufacturing apparatus includes a width determining mechanism and a gas supplier. The width determining mechanism has a body and a gas passage. The body has a path configured to allow a tape material including fibers impregnated with a resin to pass therethrough. The path has a bottom surface and a pair of wall surfaces. The pair of the wall surfaces form a gap that gradually decreases. The gas passage is provided inside the body and formed by the bottom surface having a plurality of through holes, and is in communication with the plurality of through holes. The gas supplier is configured to supply gas to the gas pass age.
