Reviews are presented of investigations into the application of conventional joining techniques to aluminum alloys reinforced with borsic or carbon fibers. Suitable joining techniques for both borsic-aluminum composites and carbon-aluminum composites are gluing, braze bonding, diffusion welding, spot welding, or resistance brazing. Other suitable techniques are riveting and screwing, using special rivets and screws. Fusion welding techniques can be used under certain conditions for joining borsic-aluminum composites, but they are unsuitable for carbon-alumnum composites because melting of the aluminum matrix in the presence of the carbon fibers leads to the formation of aluminum carbide, which results in destruction of the fiber composite. Riveting, screwing, and braze bonding of fiber reinforced aluminum alloys are discussed; the variables include temperature effects, fiber volume, fracture strength, tensile strength, melting point, elongation, alloy composition, shear strength, fracture crack initiation, adhesive strength, and metal matrix composition.
