Abstract

Radiation cured composite materials are greatly improved by enhancing the fiber to matrix bond by prewetting the fibers with an interface resin that has a curing agent mixed in with the interface resin. Furthermore, radiation curing the composite material at or near an expected operating temperature of the composite material improves the mechanical properties of the material by reducing thermally induced strains and stresses caused by thermally curing a material and subsequently cooling the material. Adding an interface resin with a curing agent to the fibers allows relatively thick parts, a must faster curing process, a wide variety of inexpensive and easily workable molding materials, the ability to maintain tight tolerances and reduce or eliminate springback, and a radiation cured material that approaches or exceeds the material characteristics of thermally cured composite materials.
