Abstract
There are provided fiber reinforced structures formed of one or more layers of reinforcing fibers contained in an electroformed, superplastic, nickel-cobalt matrix.
Claims28
A fiber reinforced structure comprising at least one layer comprised of a plurality of reinforcing fibers contained in a matrix consisting essentially of an electroformed, superplastic, nickel-cobalt alloy.
A fiber reinforced structure comprising a laminate of:
- (a) at least one layer comprised of a plurality of reinforcing fibers;
- (b) a first self-supporting layer consisting essentially of an electroformed, superplastic, nickel-cobalt alloy providing a first surface partially bonded to said reinforcing fibers and partially disposed between said reinforcing fibers;
- and
- (c) a second self-supporting layer consisting of an electroformed, superplastic, nickel-cobalt alloy providing a second surface partially bonded to said reinforcing fibers and diffusion bonded to said first surface.
A fiber reinforced structure comprised of a laminate of:
- (a) at lease one layer of reinforcing fibers formed of fibers selected from the group consisting of carbon fibers and boron fibers;
- (b) a first self-supporting layer consisting essentially of an electroformed, superplastic, nickel-cobalt alloy containing from about 35% to about 65% by weight cobalt, said first layer providing a first surface partially bonded to said reinforcing fibers and partially disposed between said reinforcing fibers;
- (c) a second self-supporting layer consisting essentially of an electroformed, superplastic, nickel-cobalt alloy containing from about 35% to about 65% by weight cobalt, said second layer providing a second surface partially bonded to said reinforcing fibers and diffusion bonded to said first surface.
A fiber reinforced structure comprising at least one layer comprised of non-conductive reinforcing fiber filaments contained within a layer consisting essentially of an electroformed, superplastic, nickel-cobalt alloy matrix formed by electrodeposition of said matrix outward from a cathode to envelope said layer of reinforcing fibers.
