Abstract: Systems and methods for the reduction of volatile component content from shaped prepregs and prepreg layups and the layups and composites formed therefrom are disclosed. One or more shaped prepregs or prepreg layups are placed within an enclosure and a flow of a non-condensing gas is introduced adjacent at least one surface of the shaped prepregs or prepreg layups, accelerating the rate and/or the completeness of removal of volatile components from the shaped prepregs or prepreg layups. The shaped prepregs or prepreg layups may be further subjected to heat, vacuum, and external pressure to facilitate removal of the volatile components. Shaped prepregs and prepreg layups with volatiles reduced in this manner may be further consolidated with heat, external pressure and/or vacuum. Beneficially, reduced matrix bleed and reduced fiber movement may be achieved during processing, reducing manufacturing time and improving part quality.

Abstract: A composite part, such as a stiffener is formed in place. A composite charge is placed on a tool spanning a mold cavity, with the centerline of the charge offset from the centerline of the mold cavity. Opposite sides of the charge are held against the tool as the charge is formed into the mold cavity. One side of the charge is held against movement on the tool while the other side of the charge is allowed to slip over the tool toward the mold cavity.

Abstract: A first process in which a fiber reinforced base is placed in a cavity of a molding die and then resin is injected into the cavity of the molding die in a state where the molding die is opened by a sum of a distance X1 and a distance at the time of completion of molding; a second process in which the molding die is closed to a state where the molding die is opened by a sum of a distance X2 and the distance at the time of completion of molding while resin in the cavity is being drained; and a third process in which the drain of the resin from the cavity is stopped and then the molding die is closed to the distance at the time of completion of molding while a die clamping pressure is maintained at a predetermined value to cure the resin, are carried out sequentially.

Abstract: Systems and processes that limit distortion of inserts (e.g., previously formed parts) in insert molding and overmolding processes. Initially, a mold may be closed (e.g., clamped) about an insert with the mold at a first temperature. After closing the mold about the insert, the mold is heated up to a second temperature (e.g., a temperature suitable for injection of the molding material) and filled with the molding material to contact (e.g., encapsulate) the insert. After the mold has been cooled, the mold may be opened and the finished part (including the insert and the solidified molding material) removed (e.g., ejected). The process may be repeated for additional finished parts. Closing the mold about the insert before heating the mold to the injection temperature advantageously limits distortion of the insert that would otherwise occur by placing the insert into the mold with the mold already at the injection temperature.
