  • Patent number: 6460240
    Abstract: A profile member of hybrid composite materials including alternating layers of metal and fiber-reinforced composite is fabricated by three successive steps. In a first step, wet composite prepreg layers impregnated with a binder are alternately stacked with metal layers, so that the uncured binder wets the surfaces of the metal layers. Next, the initial uncured layer structure is plastically deformed using successive pressure or bending deformation steps until a prescribed cross-sectional contour of the layer structure is achieved. Finally, the formed layer structure is supported and fixed in an autoclave, in which the binder is cured under an applied mechanical pressure and elevated temperature, to form the finished profile member.
