Abstract:

One aspect of the present invention is a spray gun adapted for spray-applying fiber-reinforced resins with ceramic fiber loadings of at least about 55 wt-%. Such novel spray gun has an inlet for admitting the fiber-reinforced resin; an air inlet for atomizing the fiber-reinforced resin; a catalyst inlet; and an outlet for expelling catalyzed fiber-reinforced resin from the spray gun. The spray gun also has a straight-line delivery channel in fluid communication with the resin inlet, the catalyst inlet, and the outlet. A flow actuator is provided for selectively actuating admission of the fiber-reinforced resin and the catalyst into the spray gun. The resin inlet and the catalyst inlet are disposed for admitting resin and catalyst, respectively, in line into the straight-line delivery channel. The air inlet is disposed for admitting air into the straight-line delivery channel at an acute angle with and in the direction of flow in the straight-line channel and is located after both the resin inlet and the catalyst inlet. Another aspect of the present invention is an apparatus for spray-applying fiber-reinforced resins with ceramic fiber loadings of at least about 55 wt-%.
