Abstract
A polymer composition capable of being additively manufactured includes a polymer matrix and a magnetically receptive additive. The polymer composition may be additively manufactured or extruded to form a tool which may be used to form a composite part.
Claims16
A method of making a composite part, the method comprising:
- additively manufacturing or extruding a polymer composition to form a tool, the polymer composition comprising a polymer matrix and a negative thermal expansion (NTE) additive;
- applying a composite part composition or composite part laminate on or to the tool;
- and
- exposing the tool to sufficient heat to cure the composite part composition or composite part laminate,
- wherein the polymer composition further comprises a magnetically receptive additive, and
- wherein the magnetically receptive additive comprises a substrate coated with a magnetically receptive coating material.
