Prepreg Systems

Prepreg is one of the building blocks in the ever expanding composites industry. The process of impregnating composite fibers with specialty resins transforms carbon fiber, fiberglass, aramids and other fibers from a raw state to a product that can be engineered to make parts and assemblies as diverse as golf shaft to a critical aerospace part.

‘Prepreg’ is a composites-industry slang term, meaning ‘fiber pre-impregnated with resin,’ the fiber being anything from unidirectional carbon to woven glass or aramid, and the resin either epoxy, polyester, phenolic or even thermoplastics such as PEEK or PEKK. Prepreg was invented as a practical method to insure a uniform distribution of resin and fiber throughout a composite part.

Structural composites are now part of our everyday life. Beginning with the early high end aerospace applications, prepreg is now widely used in sporting goods, industrial applications, aerospace tooling, automotive, aircraft interiors, as well as the traditional defense and aerospace applications.
