Abstract: The present invention provides a process for thermosetting pitch fibers in reduced times, at low concentrations of oxygen and at higher temperatures than previously possible. Additionally, the present invention provides a pitch fiber which has an oxygen diffusion rate to the center of the fiber which is competitive with the rate of oxidation at the fiber's surface. Further, the present invention provides a high density pitch fiber batt which thermosets without loss of fiber structure.

Abstract: Se describe un procedimiento mejorado para producir una brea anisotrópica singular que contiene metales, adecuada para la fabricación de fibras de carbono. Se añaden compuestos organometálicos aromáticos solubles a un material de alimentación carbonoso que está sustancialmente exento de brea mesofásica, y se difunde calor en la composición resultante para proporcionar un producto de brea isotrópica que contiene mesógenos y compuestos organometálicos aromáticos solubles. Seguidamente, se fracciona con disolvente el producto de brea para separar mesógenos que contienen metales de los compuestos organometálicos. Los mesógenos que contienen metales se calientan a una temperatura suficiente para provocar su fusionamiento y producir una brea mesofásica que contiene metales. En otro método, se difunde calor en el material de alimentación carbonoso para proporcionar un producto de brea isotrópica que contiene mesógenos, y se añaden compuestos organometálicos aromáticos solubles de altoupeso molecular al producto de brea isotrópica que contiene mesógenos ante el fraccionamiento con disolvente. Las fibras de carbono que contienen metales producidas a partir de la brea mesofásica presentan propiedades reforzadas de estabilización, resistencia a la tracción y módulo de tracción. Alternativamente, el fraccionamiento con disolvente o la separación se lleva a condiciones de extracción supercríticas para producir una brea mesofásica que contiene metales. Pueden añadirse compuestos organometálicos al material de alimentación carbonoso antes o después de la operación de difusión de calor.

Abstract: This invention relates to low melting solvated mesophase pitches which are suitable for spinning into carbon fibers. The solvated mesophase pitches have a lower melting point than conventional mesophase pitch but remain substantially anisotropic. The solvated mesophase can be produced as an intermediate during solvent fractionation or supercritical solvent fractionation of mesogen-containing isotropic pitches. The process is enhanced through the ability to recover pseudomesogens with an increased average molecular weight which, in combination with the solvent content, provides a fusible mesophase capable of being spun directly into infusible oriented anisotropic carbon fibers.
