Abstract
A method for the production of fiber reinforced palstic composites, in which a continuously moving array of fibers is impregnated with resin and fast cured as it passes through a shadow boundary created by a source of radiant energy such as ultraviolet light. The method is useful for the production of axial composites such as tubes, pipes, conduits, ducts and the like, which may be created without mandrels by passing the array of fibers through closed dies. The method is also useful with open or rolling dies to create nonaxial composites such as wall panels, guard rails, vehicle body parts, and the like.
