Technical Field

[0001] The utility model relates to a composite device, in particular to a composite device for prepreg tapes, belonging to the technical field of prepreg tape production. Background Art

[0002] Prepreg tape is a composite material composed of a matrix and a reinforcement with continuous fibers, and is widely used in the production of various types of sheets. Composite prepreg tape is formed by laminating a reinforcement layer prepreg tape with transverse fibers on a bottom prepreg tape with longitudinal fibers. Therefore, the composite prepreg tape has high toughness and impact resistance in both longitudinal and transverse directions.

[0003] Chinese patent number CN217968492U provides a composite device for prepreg tapes, comprising: a first frame; at least one unwinding seat, mounted on the first frame, the unwinding seat can place a material roll for providing a bottom prepreg tape; the composite device is defined with a feeding path for the bottom prepreg tape to move, the first frame is defined with a discharge area located on the feeding path, the discharge area is for a worker to place a sheet of reinforcing layer prepreg tape on the bottom prepreg tape located at the discharge area; a composite machine, comprising a second frame, an active roller rotatably mounted on the second frame, a pressing roller located on the upper side of the active roller, and a heating pipe at least partially located inside the active roller, the heating pipe being configured to allow a heating fluid to flow to heat the active roller; the feeding path passes between the active roller and the pressing roller, the pressing roller being configured to be movable in the vertical direction to press the bottom prepreg tape and the reinforcing layer prepreg tape located between the pressing roller and the active roller into a composite prepreg tape.
