TLDR
In this paper, reinforced epoxy resins are reinforced by incorporating carbon fibres which have been surface oxidized by an oxidizing atmosphere at an elevated temperature, which is a modification of the traditional reinforced epoxide resins.Abstract:

Recycling carbon fibre
John Davidson,Roy Price +1 more
TL;DR: In this article, a method of recycling composite material comprising carbon fibres and a resin was proposed, where the generated fumes were removed from the heating portion in a controlled manner, such that the percentage of oxygen in the atmosphere in the heating part was controlled.

Method for oxidation stabilization of pitch-based matrices for carbon-carbon composites
Patrick M. Sheaffer,J.L. White +1 more
TL;DR: In this article, an oxidation process for stabilization of pitch-based matrices in the fabrication of carbon-carbon composites is proposed, where the matrix is fixed in place within the preform so that softening, bloating, and expulsion of the matrix are avoided when the body is carbonized.

Exfoliated graphite fibers and associated method
TL;DR: In this paper, a method of producing exfoliated graphite fibers is described, which intercalates the fibers and then exfoliates the intercalated fiber by heating.

Method for the manufacture of carbon-carbon composites
Michael F. Baud,Jay A. Harvey +1 more
TL;DR: A method for manufacturing carbon-carbon composite bodies consisting essentially exclusively of carbon, of about 20 to about 96 weight percent from carbon fiber, from 0 to about 72 weight% from a carbonaceous flour, and from about 4 to about 15 weight % from carbonized resin, which consists in forming a mat by allowing a mixture of the solid ingredients to settle to equilibrium height by the force of gravity or by centrifugation in a solution of the resin and an appropriate solvent, then pressing the settled solids at up to about 100 psi and removing the excess liquid therefrom.
Patent
Microwave and plasma-assisted modification of composite fiber surface topography
TL;DR: In this article, a novel method for producing an undulated surface on composite fibers using plasma technology and microwave radiation is presented, which improves the mechanical interlocking of the fibers to composite resins and enhances the mechanical strength and interfacial sheer strength of the composites in which they are introduced.
