CLAIMS:
1. A modular chain link for use in constructing a modular conveyor chain wherein said chain link includes a plurality of spaced link ends projecting from opposite sides
of a main body of the chain link, said plurality of spaced link ends being adapted to intermesh on each of said opposite sides with adjacent links and including substantially axially aligned openings adapted to receive connecting pins for pivotally joining the modular chain link together with the adjacent links, said modular chain link is injection molded from a polymer including a fibrous filler material which increases the tensile strength of said link, said filler material being less than about 30 weight percent of the molded chain link.
2. The modular chain link of claim 1 wherein the polymer is selected from the group consisting of polyamide, acrylonitrile-butadiene-styrene, polypropylene, polyphenylene sulfide, polyurethane, polyketone, acetal and polyethylene.
3. The modular chain link of claim 1 wherein the filler material is selected from the group consisting of glass fiber, carbon fiber, aramide and stainless steel.
4. The modular chain link of claim 1 wherein said filler material is between about 5 and about 25 weight percent of said molded chain link.
5. The modular chain link of claim 1 wherein the said filler material is between about 10 and about 20 weight percent of said molded chain link.
6. The modular chain link of claim 1 wherein said filler material is in the form of long fibers.
7. The modular chain link of claim 6 wherein said fibers have a length between 0.125 inches and 0.5 inches.
