Abstract
Qualitative determination of resin type in articles from fiberglass-reinforced polymerized thermosetting resins is possible by the use of infrared spectroscopy. The technique involves grinding the resin and glass to a fine powder and measuring the spectrum in a potassium bromide pellet. Three types of thermosetting resins can he easily distinguished in the presence of high (60%–70%) concentration of fiberglass. These are (1) unsaturated polyester styrene, (2) anhydride-cured epoxy, and (3) amine-cured epoxy.
