ABSTRACT:
A polyester composite propeller spinner (1) has a conical wall (2), radial internal support gussets (3), and means for attaching to a propeller hub. Improved impact strength is achieved by combining a vinyl terminated liquid reactive compound with a polyester resin and adding a plurality of fiberglass fibers. The fiberglass fibers are in at least two fiber lengths, having a 2:1 ratio of long to short fibers. A propeller spinner formed from such a composition has an impact strength of greater than 4.84 Kg-m (35 ft-lbs) .
