Sizing for carbon fibers with uncapped or capped linear polyamideimides. The uncapped linear polyamideimides useful as carbon fiber sizings generally contain repeating units having the general formula: [Figure] or [Figure] Wherein R2=a trivalent organic radical and generally benzenetriyl; R3=a divalent organic radical; and n=an integer sufficiently large to provide a strong, tough coating. Useful capped, linear polyamideimide oligomers may be formed by including end caps with an unsaturated functionality (Y) containing a residue selected from the group consisting of: [Figure] [Figure] [Figure] wherein R1=lower alkoxy, aryl, aryloxy, substituted alkyl, substituted aryl, halogen, or mixtures thereof; j=0, 1 or 2; i=1 or 2; G=-CH2-, -O-, -S-, -SO2-, -SO-, -CO-, -CHR-, or -CR2-; T=methallyl or allyl; Me=methyl; and R=hydrogen, lower alkyl, or phenyl. Prepregs and composites having carbon fibers sized with such polyamideimides are also described.
