Abstract
One or more layers of structured thermoplastic polymer, such as a light weight veil of thermoplastic polymer fibers, are located within the interleaf zone of laminates that are composed of fibrous layers and thermosetting resin. The thermoplastic veils are used in the interleaf zones as a replacement for thermoplastic toughening particles. The structured thermoplastic polymer may be coated with a conductive material to improve electrical conductivity through the laminate.
