Abstract: The present disclosure relates generally to carbon fibers having high tensile strength and modulus of elasticity, as well as a process for the manufacture of such carbon fiber. The process comprises spinning a polymer/solvent solution into a solvent/water bath in the range of 78% - 85% solvent, thereby producing a dense fiber structure, and subsequently carbonizing the polymer precursor fiber at a lower than typical carbonization temperature to form carbon fibers.

Abstract: The present disclosure relates generally to a process for producing polymer fibers, typically polyacrylonitrile-based fibers, the properties of which are controlled by certain parameters of the process, such as the amount of jet stretch, the amount of wet stretch, and the amount of hot stretch employed. The present disclosure also relates to a process for producing carbon fiber from such polymer fibers.

Abstract: The present disclosure relates to a continuous process for treating carbon fiber, the process comprising exposing one or more carbon fibers to plasma comprising reactive species derived from an organic compound comprising at least one vinyl group and/or other gas that can modify the carbon fiber surface to promote interphase formation at a plasma pressure of 10 to 200 mTorr. The present disclosure also relates to a composite material comprising one or more treated carbon fibers obtained by the process described herein and a matrix resin, wherein an interphase layer is disposed between each carbon fiber and the matrix resin.

Abstract: The present disclosure relates generally to a process for producing polymer fibers, typically polyacrylonitrile-based fibers, the morphology of which is controlled by the use of a polymer additive to form a polymer blend with polyacrylonitrile, which is then subjected to certain coagulation and washing conditions. The present disclosure also relates to carbon fibers produced by processing the polymer fibers made.

Abstract: The present disclosure relates to a process for treating carbon fiber, the process comprising: a) exposing one or more carbon fibers to plasma comprising carbon dioxide, and/or a reactive species thereof, thereby forming one or more pre-treated carbon fibers; and b) exposing the one or more pre-treated carbon fibers formed in step a) to a further surface treatment, thereby forming the treated carbon fiber. The present disclosure also relates to a composite material comprising one or more treated carbon fibers obtained by the process described herein and a matrix resin.
