ABSTRACT:
Accordingly the present invention provides a method of construction using a raphite or carbon fiber composite structure with a low temperature cure epoxy resin system to have a material system of minimum weight, high strength and high stiffness which eliminates a secondary bonding operation to effect load transfer between structural components and to have service life compatible to its use environment. A graphite or carbon fiber, preimpregnated with a low temperature (195.degree. F.) curing epoxy resin prepared in the form of unidirectional tape, is laid up or wrapped over a contour form and then cured to provide stiffness and strength equal to or exceeding those of a selected metal such as aluminum or steel.
