Can someone rank these materials based on ability to resist solvents and fuels?
Thanks.
G10, micarta, and carbon fiber are epoxy resin impregnated
fiber glass fabric, cloth / canvas, and carbon fiber fabric respectively.
The ability to resist fuels or solvents is entirely dependent on what epoxy resin was used to make the material in question. It has nothing to do with which reinforcing material was used.
Since there are thousands of epoxy resin variations you can have thousands of different results.
Also, since there are really no controlling specifications for these materials
as made for knife handles, there is no way to rank them for strength as it will depend on exactly which weaves were used, how many plies, and the diameters of the fibers used in the weaves.
Further, again since there is no controlling specification at all for surface finish of these materials, the surface finish can vary micarta to micarta, G10 to G10, Carbon fiber to Carbon fiber. Usually, the handles of a given material from a single maker will be fairly uniform in strength, finish, and solvent resistance.
Suffice to say that any of these will make a very strong handle. Your best bet is to talk to people who have handles of the material you are interested in from the maker you are looking at. Better is to actually handle one that makers products to see how that maker finishes that material.
Hope that helps,
