ABSTRACT:
Apparatus for uniformly blending and applying a mixture of a two part resin and radar absorbing fibers to a surface. The fibers retain their length distribution after mixing and application. The unreacted resin base and catalyst components of the resin, one or both of which are premixed with the fibers, are brought together in a dispenser which then conducts them to an in line motionless mixer element and from there to a nozzle which has an output orifice sufficient for the desired length of the fibers to retain the desired size distribution of the fibers in the applied resin. The apparatus is also capable of applying other types of fibers or other solid materials within the liquid polymer matrix with minimal breakage to the solid component.
