    摘要: Disclosed herein are systems and methods for manufacturing a part. An example method comprises heating a consolidated laminate sheet, comprising multiple plies each made of fibers embedded in a thermoplastic resin, to a heated temperature below a melting temperature of the thermoplastic resin to form a heated consolidated laminate sheet. The method also comprises forcing the heated consolidated laminate sheet against a contoured forming surface of a mold until a shape of the heated consolidated laminate sheet corresponds with a contoured shape of the contoured forming surface of the mold.

    摘要: A method for joining a first thermoplastic substrate and a second thermoplastic substrate, each including a polyaryletherketone material having a first melting temperature. The method includes co-consolidating a first semicrystalline thermoplastic film with the first thermoplastic substrate to yield a first co-consolidated structure. The first semicrystalline thermoplastic film defines a first bonding surface of the first co-consolidated structure and includes a polyaryletherketone material having a second melting temperature that is less than the first melting temperature. The method further includes co-consolidating a second semicrystalline thermoplastic film with the second thermoplastic substrate to yield a second co-consolidated structure. The second semicrystalline thermoplastic film defines a second bonding surface of the second co-consolidated structure and includes a polyaryletherketone material having a third melting temperature that is less than the first melting temperature. The method further includes fusing the first bonding surface to the second bonding surface. The method yields a stacked structure.

    摘要: Provided are induction heating cells including pressure bladders used for supporting dies and methods of using these induction heating cells. A pressure bladder may be disposed between a die and a bolster of the cell. Even when the bolster is deformed during operation of the cell, the pressure bladder continues to provide uniform support to the die thereby preserving integrity of the die and prevents its cracking or braking. As such, the cell may be operated at a higher processing pressure inside the cavity formed by the die without further strengthening the bolster. The bolster is allowed to deform without compromising the integrity of the die. The deformation of the bolster is compensated by the shape change of the pressure bladder. The number and/or position of the bladders in the cell may depend on the shape of processed parts.
