COMPOSITE TOOL AND METHOD FOR FORMING COMPOSITE COMPONENTS

摘要

PROBLEM TO BE SOLVED: To provide a composite tool and a method for forming composite components.SOLUTION: A composite tool 100 includes: a three-dimensionally printed polymer body 103, the body having a geometry corresponding to at least one surface of a gas turbine component; and a coating overlying the body 103, the coating providing the three-dimensionally printed polymer body 103 with a greater resistance to heat exposure than an uncoated three-dimensionally printed polymer body 103. A method for forming a composite component includes steps of: providing a composite tool 100; laying up a plurality of composite plies on a surface of the composite tool 100; densifying the composite plies to form a composite component; and removing the composite tool 100 from the composite component. The composite component includes a geometry corresponding to at least a portion of the composite tool 100.SELECTED DRAWING: Figure 1
