Micarta is the trade name for the company that created the process.


The original micarta was developed by George Westinghouse. As a laminate,
Westinghouse sold it well into the 1960s. GE had a similar product,
textolite, which was used for countertops, gears, etc. Both are similar to
Formica.


Micarta is also know generically as "Phenolic". However, phenolic does
not always mean it is made with phenolic resin. The first Micarta was
made with Bakelite, a phenolic resin, but for years now a very common
phenolic is G10, which every one here would recognize as fiberglass
filled epoxy circuit board material. I have machined several different
types of phenolic over the years, linen filled, fiberglass filled,
carbon fiber filled, paper filled. etc. G10 is quite strong and is
easy to glue with epoxy if the surface is roughed up a bit first.

G11 is better, stronger! FR5
