Abstract: The invention relates to a method for producing a composite component, said composite component being made of a matrix composite material made of a reinforcing material and a matrix material. The reinforcing material is coated with pyrolytic carbon, and a preform is made from the reinforcing material. The reinforcing material is coated with the pyrolytic carbon in order to produce the pre-form. The pyrolytic carbon is deposited on the reinforcing material from the gas phase. The pre-form at least partly has an open pore structure, said open pore structure being infiltrated with the matrix material, thus forming the composite component. The invention further relates to an alternative method for producing a composite component, wherein the pyrolytic carbon is deposited on the reinforcing material from the gas phase, a mixture of the reinforcing material and the matrix material is formed, and the composite component is formed by sintering the mixture.

Abstract: Golf club structures, including club heads and shafts, composed of composites comprised of a matrix of metal, such as an aluminum alloy, or a plastic material and a fiber such as graphite or a ceramic, which may be whiskerized, and which may also be selectively weighted as in the toe and heel of a club head, with heavy particles such as tungsten metal. The club structure may also be surface hardened by applying a coating of fullerenes to a metal club structure and heat treating it to produce a hard coating of metal carbide, preferably by coating a titanium golf club structure with fullerenes and heat treating the coated structure to produce a titanium carbide surface.

Abstract: A quantity of reinforcing material is formed into a shaped mass bound together by an inorganic binder. This shaped mass is compounded with a quantity of a molten matrix metal by a pressure casting method. The molten matrix metal includes a quantity of a certain element with a strong tendency to become oxidized, and the inorganic binder includes a metallic oxide which, when brought into contact at high temperature with this certain element, is reduced thereby in an exothermic reaction. During the pressure casting, extra heat is produced as the certain element reduces the metallic oxide, and this aids good penetration of the matrix metal into the interstices of the reinforcing material. The metal remaining from the oxide is dispersed in the matrix metal. This metallic oxide may be silica, zirconia, chromium oxide, yttrium oxide, cerium oxide, ferric oxide, zirconium silicate, antimony oxide, or a mixture thereof; and the certain element may be lithium, calcium, magnesium, aluminum, beryllium, titanium, zirconium, or a mixture thereof.
