What are Phenolics, and what are their applications?

Micarta became a brand name when it was developed by George Westinghouse in the early 1900’s using phenolic resins.  Micarta is now used as the general brand name term for resin impregnated fibre compounds.  This material is made from phenolic resins used to impregnate paper and cotton fabric which are cured under pressure and high temperatures to produce laminates.

Micarta industrial laminates are typically phenolic, epoxy, silicon-based thermoset materials reinforced with fiberglass, cotton, cloth, paper, carbon fiber, moly, teflon, and others.  Pressure and heat is applied to layers of laminations which yields a chemical reaction (polymerization) which turns the layers into high-pressure thermosetting industrial laminated plastic.  There are numerous commercial grades which industrial laminates are manufactured in.
