PROCESS FOR TREATING CARBON FIBER AND COMPOSITE MATERIALS HAVING TAILORED INTERPHASE STRUCTURE MADE FROM SUCH TREATED CARBON FIBER

摘要

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.
