Abstract
In the manufacture of composite product, raw composite is layered on a shape or form and cured at a higher temperature. With some shapes, it is difficult or impossible to apply sufficient pressure to force and consolidate the composite material to adequately conform to the desired final shape during the curing process. The expandable tacky tape of this invention is comprised of a viscous medium incorporating thermally expandable material. Applied over the raw composite, the expandable tacky tape effectively forces the composite to conform to the desired shape during curing.
