摘要： The invention is directed to carbon fibers having high tensile strength and modulus of elasticity. The invention also provides a method and apparatus for making the carbon fibers. The method comprises advancing a precursor fiber through an oxidation oven wherein the fiber is subjected to controlled stretching in an oxidizing atmosphere in which tension loads are distributed amongst a plurality of passes through the oxidation oven, which permits higher cumulative stretches to be achieved. The method also includes subjecting the fiber to controlled stretching in two or more of the passes that is sufficient to cause the fiber to undergo one or more transitions in each of the two or more passes. The invention is also directed to an oxidation oven having a plurality of cooperating drive rolls in series that can be driven independently of each other so that the amount of stretch applied to the oven in each of the plurality of passes can be independently controlled.

摘要： The invention provides nanostructure composite porous silicon and carbon materials, and also provides carbon nanofiber arrays having a photonic response in the form of films or particles. Composite materials or carbon nanofiber arrays of the invention are produced by a templating method of the invention, and the resultant nanomaterials have a predetermined photonic response determined by the pattern in the porous silicon template, which is determined by etching conditions for forming the porous silicon. Example nanostructures include rugate filters, single layer structures and double layer structures. In a preferred method of the invention, a carbon precursor is introduced into the pores of a porous silicon film. Carbon is then formed from the carbon precursor. In a preferred method of the invention, liquid carbon-containing polymer precursor is introduced into the pores of an porous silicon film The precursor is thermally polymerized to form a carbon-containing polymer in the pores of the porous silicon film, which is then thermally carbonized to produce the nano structured composite material. A carbon nanofiber array is obtained by dissolving the porous silicon. A carbon nanofiber array can be maintained as a film in liquid, and particles can be formed by drying the material.

摘要： A composite prepreg yarn designed and constructed is a very large, strong yarn with resin infused throughout, which can be used to prepare composite preforms via conventional Maypole braiding or other textile processes. The invention increases the loads that can be transmitted by the cured yarn in a composite structure, decreases the stickiness that can prevent their use in braiding and other textile processes, provides protection to the high-strength fibers from abrasion that is encountered during and after composite preform manufacturing via braiding.
