[Reference Request] Sizing Literature on Carbon Fiber or Metal into Thermoplastic Matrix

[Lloyd_1]

Hello! I am trying to find some information about preparation of fibers for increased adhesion with the polymer matrix (i.e. 'sizing'), but I'm having a difficult time finding sources.

Most of what I am finding is related to epoxies and laminates, whereas I am trying to find current industry standards with respect to thermoplastics. For instance, creating a copper core filament with nylon matrix. Or pitch carbon fiber bundles prepared with an oxidation agent to produce acidic functional groups on the CF surface. I would love to find more detail on exactly how this is done.

Some of what I'm trying to understand more of includes the respective interfacial energy, surface tensions, core-matrix compatibility, and sizing methods.

Supplemental Information:
[ul]
[li]Matrices Investigated - Nylon, PLA, TPU, ABS[/li]
[li]Fibers - all CF, metals[/li]
[/ul]

If anyone could recommend a solid textbook or journal summary for reference, that would be fantastic. I would also love any advice regarding this topic. Thank you!


Best Regards,

Lloyd

There have been many articles published on surface treatments of carbon fiber. Sizing on carbon fibers is like starching your shirt. It is there to improve handling of the fibers, not to improve adhesion. The patent literature would be a good place to look for information on surface treatments. The optimum treatment method depends very much on the substrate material. Carbon and metals have little in common in this area.
