This article focuses on epoxy because this resin category has widespread use and because it is tested using quality control measures typical of most resin systems. A typical resin system will consist of one or more epoxy resins, a curing agent, and a catalyst to control the rate of reaction. The article describes the component material tests, mixed resin system tests, and prepreg tests for the resin system. The tests include high-performance liquid chromatography, infrared spectroscopy, and gel permeation chromatography. The article contains a table that lists typical resin and prepreg property tests.
