utility poles by wrapping the material around a portion of the utility pole and causing a current to flow through the conductive fibers to resistively heat the material to the resin. The composite material can also be incorporated into molds to produce cured composite parts. The composite material is also used in the construction of large parts without the need for huge, expensive molds. The conductive fibers in composite parts are oriented in a manner to ensure that the entire part is thoroughly heated during the curing process.

5578384 BETA TITANIUM-FIBER REINFORCED COMPOSITE LAMINATES
5650220 FORMABLE REINFORCING BAR AND METHOD FOR MAKING SAME Greenwood Mark Granville, OH, UNITED STATES assigned to Owens-Coming Fiberglas Technology Inc A formable reinforcement bar, a process for producing a formable reinforcing bar and a supported structure including a formable reinforcement bar are provided. The reinforcement bar includes a body portion of a fiber reinforced thermoplastic material. The process involves laminating multiple layers of thin strips or bundles of fiber reinforced thermoplastic to produce the formable rebar. The formable rebar may be produced at remote locations such as a construction site. The supported structure includes a composite material having a formable rebar embedded therein.
Kingston William Chino Hills, CA, UNITED STATES assigned to Ticomp Inc A beta titanium-fiber reinforced composite laminate comprising at least one layer of beta titanium alloy and at least one layer of fiber reinforced composite, wherein the layer ofbeta titanium alloy has a yield strength to modulus of elasticity ratio that is substantially similar to the strength to modulus of elasticity ratio of the first layer of fiber reinforced composite. Also, a method of preparing a beta titanium-fiber reinforced composite laminate comprising the steps of, first, providing a beta titanium alloy having a first yield strength to modulus of elasticity ratio; then, heating the beta titanium alloy at a first preselected temperature for a first preselected time to produce a beta titanium alloy having a second yield strength to modulus of elasticity ratio; and then, adhering a fiber reinforced composite having a strength to modulus of elasticity ratio to the beta titanium alloy to produce a beta titanium-fiber reinforced composite laminate; wherein the first preselected temperature and the first preselected time are preselected such that the second yield strength to modulus of elasticity ratio of the beta titanium alloy is substantially similar to the strength to modulus of elasticity ratio of the fiber reinforced composite.

Process for the preparation of a flexible, thermoplastic, composite filament, containing continuous fibers basically consisting of a flexible sheath made of polyolefinic resin which covers a bundle of fibers impregnated with a polyolefmic resin, wherein the inorganic fibers are treated with a solution containing additives which improve the compatibility between reinforcement and polymeric matrix after transformation into end products.
A function ally gradient composite material containing copper and carbon as main components and having a predetermined shape, in which the composition ratio of the copper to the carbon in the material continuously varies in at least one predetermined direction. The material is manufactured, for example, by impregnating carbon felt with a resin and thermo-compressively molding the impregnated felt, carbonizing the resin by baking provide a
