An apparatus for manufacturing an elongate composite element in undefined lengths,
the composite element containing reinforcement fibers embedded in a matrix based
on a composition containing a curable resin, including a vacuum chamber, rigid-walled
inlet tubing, an impregnation chamber, rigid-walled transfer tubing between the
vacuum chamber and the impregnation chamber, a sizing die and, downstream of the
sizing die, irradiation tubes providing radiation in the ultraviolet-visible spectrum
to prepolymerize the resin.
