Rubber-fiber hybrid
View Patent ↗An animal chew toy and a method for making such that comprises a fabric having a plurality of fibers and a polymeric material that contacts the fabric wherein the polymer material engages with the plurality of fibers.
1. An animal chew toy comprising:
a woven or non-woven fabric shaft having a plurality of fibers, said fabric shaft having a length and end portions, wherein one or a plurality of void spaces are located between said plurality of fibers; and
an over-molded polymer material portion, wherein said over-molded polymer material portion comprises a polymer resin and said over-molded polymer material portion is located only at the end portion of said length of said fabric shaft and within said one or a plurality of fiber void spaces and is mechanically engaged to said fibers,
further characterized in that said over-molded polymer surrounds one or more of said fibers at said end portions,
wherein said fabric shaft is selected from the group consisting of oriented polyethylene fiber and poly-paraphenylene terephthalamide fiber having an ultimate tensile strength of 2.1 GPa and higher.
2. The animal chew of claim 1 wherein said fabric shaft has one or a plurality of end portions, and said polymer material portion engaged to said fibers is located at said one or plurality of end portions.
3. The animal chew of claim 1 wherein said polymer resin is a thermoplastic material.
4. The animal chew of claim 1 wherein said polymer resin is an elastomeric material.
5. The animal chew toy of claim 1 wherein said over-molded polymer material portion is a molded shape selected from the group consisting of a sphere, a hemisphere, a cylinder, a prism, a cone, knuckles and combinations there of.
6. An animal chew toy comprising:
a woven or non-woven fabric shaft having a plurality of fibers, said fabric shaft having a length and end portions, wherein one or a plurality of void spaces are located between said plurality of fibers, and
an over-molded polymer material portion wherein said over-molded polymer portion comprises a polymer resin and said over-molded polymer material portion is located only at the end portions of said length of said fabric shaft and within said one or a plurality of fiber void spaces and is chemically engaged to said fibers,
further characterized in that said over-molded polymer surrounds one or more of said fibers at said end portions,
wherein said fabric shaft is selected from the group consisting of oriented polyethylene fiber and poly-paraphenylene terephthalamide fiber having an ultimate tensile strength of 2.1 GPa and higher.
7. The animal chew toy of claim 6 wherein said polymer resin is a thermoset material.
