Abstract

A tool for forming a composite part and a method of making the tool and the composite part are disclosed. The tool includes a top surface that supports the composite part during forming, the top surface comprising a first lateral portion and a second lateral portion arranged on either side of a central part contacting surface; a first integrated heat sink arranged on an opposite surface of the top surface, wherein a shape of the first integrated heat sink is based on a thermal topology optimization process of the tool; a first vacuum port arranged at a first location on the first lateral portion; and a second vacuum port arranged at a second location on the first lateral portion, wherein the first vacuum port and the second vacuum port provide access to a vacuum pump to provide at least a partial vacuum to the top surface during composite part formation.
