ABSTRACT:
Tools for compacting composite parts are disclosed. These tools are used while layers of composite material, such as tows or laminae, are being deposited onto a fabricating surface, such as a mold or other forming tool. The compacting tool is typically divided into a series of narrow segments, each segment able to advance or retreat individually so as to conform to the surface of a composite part being formed. Pressurized fluid, such as air or hydraulic fluid, or non-pressurized internal bladders with incompressible fluid, are used to evenly apply pressure to the segments in order to compact the material with which the tool and the segments are in contact. The compacting tool thus helps eliminate voids and helps the material conform to the desired shape on the forming tool.
