Abstract
Coating a substrate with a reinforced resin matrix comprised of liquid resin and reinforcing material can be accomplished with an apparatus where the liquid resin and the reinforcing material are mixed external to the apparatus prior to impacting the substrate. The liquid resin is directed through a cylinder 12 and then through an orifice 7 in nozzle 1, while the reinforcing material is carried in a gas stream through cavity 13, around cylinder 12, and past the nozzle 1. As the reinforcing material passes the nozzle 1, it is drawn into the liquid resin. Due to the distribution of the reinforcing material around the liquid resin flow, the reinforcing material is substantially homogeneously wetted by the liquid resin prior to impacting the substrate.
