Composite part compaction device

A non-transitory computer readable medium embodying programmed instructions which, when executed by a processor, are operable for performing a method for compacting a laminate onto a surface of a forming tool, the method comprising:

• placing the laminate onto the forming tool;
• aligning a pressure foot of a compaction device over the laminate, wherein the compaction device is distinct from the forming tool;
• rotating electromagnets of the compaction device into alignment with a surface of the forming tool;
• gripping the compaction device directly to the surface of the forming tool prior to initiating compaction of the laminate, by activating the electromagnets;
• compacting the laminate with the pressure foot of the compaction device while the electromagnets remain activated, wherein the pressure foot is operated independently of the electromagnets;
• and
• removing the compaction device from the forming tool.

A method for laying up a composite preform, the method comprising:

• placing a laminate comprising at least one ply of fiber reinforced material onto a surface of a forming tool;
• aligning a pressure foot of a compaction device over the laminate, wherein the compaction device is distinct from the forming tool;
• rotating electromagnets of the compaction device into alignment with a surface of the forming tool;
• applying gripping forces directly between the compaction device and the forming tool prior to initiating compaction of the laminate, by activating the electromagnets;
• compacting the laminate to the forming tool by controllably applying compaction forces to the laminate via the pressure foot while maintaining the gripping forces via the electromagnets;
• laying up at least one ply atop the compacted laminate at the forming tool;
• and
• repeating the steps of compacting and placing.
