Micarta is a trade name like "Cresent" wrench vs adjustable wrench. In other words all micarta can be phenolic but not all phenolic can be micarta...
Anyway, enough symantics. Most phenolics are made of polyester and we glue them with epoxies with no issues so there should be no worries there.
G10, my phenolic of choice is a fiberglass substrate base with an epoxie resin base. It is much stiffer and stronger and about 20% heavier. Oddly enough, it is easier to sand and file.
G10 is generally only available in black and is a bit more expensive but it doesn't show weave as badly as poly phenolic or "Micarta".
I keep many different sizes of Phenolic on hand and G10 as well.
