Abstract
A method of making a part comprising stacking a plurality of uncured composite sheets to form an uncured composite stack. The method also comprises interposing a resistor wire between an adjacent two of the uncured composite sheets of the uncured composite stack. The method further comprises applying heat to the uncured composite stack externally of the uncured composite stack to at least partially cure the plurality of uncured composite sheets. The method additionally comprises transmitting an electric current through the resistor wire to generate heat, from the resistor wire, internally within the uncured composite stack to at least partially cure the plurality of uncured composite sheets. Applying heat to the uncured composite stack externally and generating heat internally converts the plurality of uncured composite sheets into a plurality of cured composite sheets and converts the uncured composite stack into a cured composite stack.
