Molybdenum composite hybrid laminates and methods

A method of improving a cure cycle of a composite structure using molybdenum foil layers, the method comprising:

• treating a surface of each of a plurality of molybdenum foil layers;
• interweaving the surface treated molybdenum foil layers with a plurality of composite material layers, the molybdenum foil layers being thermal and temperature controllers improving a cure cycle of a composite structure;
• bonding with an adhesive layer each of the surface treated molybdenum foil layers to adjacent composite material layers to form a molybdenum composite hybrid laminate having improved yield strength;
• and,
• using the molybdenum composite hybrid laminate in the composite structure to improve the cure cycle of the composite structure,
• wherein the molybdenum foil layers have a sufficient stiffness to leverage a fiber tensile strength and a fiber stiffness of off-axis fibers in adjacent composite material layers via Poisson's effects in the molybdenum foil layers, and the molybdenum foil layers further have a sufficient thermal conductivity to enable the molybdenum foil layers to act as thermal and temperature controllers improving the cure cycle of the composite structure.
