Consolidation tooling is used in a continuous compression molding machine to produce a fiber reinforced thermoplastic part having a varying height. The tooling includes first and second tool dies adapted to compress and form a multi-ply stack of thermoplastic prepreg into a part, and at least a first tooling sleeve movable through the first and second tool dies. The tooling sleeve has at least a first tapered portion engageable with the multi-ply stack.

1. Consolidation tooling for use in a continuous compression molding machine to fabricate a fiber reinforced thermoplastic part having a varying height, comprising: a first tool die and a second tool die, the first tool die and the second tool die each adapted to mold a multi-ply stack of thermoplastic prepreg into a part; andat least a first tooling sleeve movable between the first tool die and the second tool die, the first tooling sleeve having at least a first tapered portion engageable with the multi-ply stack of thermoplastic prepreg,wherein the first tool die is tapered along its length substantially complementary to the first tapered portion of the first tooling sleeve,a third tool die and a fourth tool die, the third tool die and the fourth tool die each adapted to compress and mold the multi-ply stack of thermoplastic prepreg into a web region of the part,a first tooling member attached to the first tool die and a second tooling member attached to the second tool die, wherein the first tooling member applies a first compressive force directly to the multi-ply stack of thermoplastic prepreg and the second tooling member applies a second compressive force directly to the multi-ply stack of thermoplastic prepreg. 2. The consolidation tooling of claim 1, wherein: the first tapered portion of the first tooling sleeve is a first tapered flange portion, andthe first tooling sleeve includes a second tapered flange portion engageable with the multi-ply stack of thermoplastic prepreg. 3. The consolidation tooling of claim 2, wherein: the second tool die is tapered substantially complementary to the second tapered flange portion of the first tooling sleeve. 4. The consolidation tooling of claim 2, wherein the first tapered flange portion and the second tapered flange portion of the first tooling sleeve are tapered in opposite directions. 5. The consolidation tooling of claim 1, wherein the first tooling sleeve includes a web portion connected with a first tapered flange portion. 6. The consolidation tooling of claim 1, wherein the third tool die is disposed within the first tooling sleeve. 7. The consolidation tooling of claim 6, wherein the third tool die is elongate and has a substantially constant cross section along its length. 8. The consolidation tooling of claim 1, wherein at least one of the group consisting of the first tool die, the second tool die, and the first tooling sleeve includes non-uniform thickness contours. 9. The consolidation tooling of claim 1, wherein the first tooling sleeve is generally U-shaped in cross section. 10. The consolidation tooling of claim 1, wherein the first tooling sleeve is elongate and is curved along at least a portion of its length. 11. The consolidation tooling of claim 1, wherein the first tooling sleeve is configured to mold the multi-ply stack of thermoplastic prepreg into a beam having a cross sectional shape selected from the group consisting of: an I-shape,a J-shape,a Z-shape,a T-shape, anda C-shape. 12. The consolidation tooling of claim 1, further comprising: a second tooling sleeve movable between the first tool die and the second tool die, the second tooling sleeve having at least one tapered flange portion. 13. Consolidation tooling for use in a continuous compression molding machine to fabricate a fiber reinforced thermoplastic part having a varying height, comprising: a first tool die and a second tool die, the first tool die and the second tool die each adapted to mold a multi-ply stack of thermoplastic prepreg into a part, wherein the first tool die and the second tool die are horizontally opposed to each other;a third tool die and a fourth tool die, wherein the third tool die and the fourth tool die are each adapted to apply a compressive force in a vertical direction to the multi-ply stack of thermoplastic prepreg and mold the multi-ply stack of thermoplastic prepreg into a web region of the part, wherein the third tool die and the fourth tool die are vertically opposed to each other;a first tooling member attached to the first tool die, wherein the first tooling member extends vertically along an inwardly facing surface of the first tool die;wherein the inwardly facing surface of the first tool die is tapered along its length and the first tooling member applies a first compressive force, in a horizontal direction directly to the multi-ply stack of thermoplastic prepreg;a second tooling member attached to the second tool die, wherein the second tooling member extends vertically along an inwardly facing surface of the second tool die;wherein the inwardly facing surface of the second tool die is tapered along its length and the second tooling member applies a second compressive force, in the horizontal direction directly to the multi-ply stack of thermoplastic prepreg;a first tooling sleeve movable between the first tool die and the second tool die, the first tooling sleeve having at least a first tapered portion and at least a second tapered portion; anda second tooling sleeve movable between the first tool die and the second tool die, the second tooling sleeve having at least a first tapered portion and at least a second tapered portion. 14. The consolidation tooling of claim 13, wherein the first and second tooling sleeves are configured to mold the multi-ply stack of thermoplastic prepreg into a beam having a cross sectional shape comprising: a cap region; anda single bottom flange connected to the cap region by the web region, wherein the cap region extends parallel with a longitudinal axis of the beam along its length and the single bottom flange is angled with respect to the longitudinal axis of the beam along its length.
