Abstract
A method and apparatus for resin injected pultrusion is provided. The method comprises injecting a resin material into a reinforcement pack at a sufficiently high pressure such that the pressure in the injection area or weir of the injection die is substantially equal to the compression pressure applied by the exit portion of the injection die. An apparatus for achieving the method is also provided.
