Abstract
A riser for an archery bow is formed from a fibrous composite material, the matrix of which may be a high heat distortion thermoplastic polymer, a very high heat distortion thermoplastic polymer, or a combination thereof. The riser may incorporate a spine formed from a different polymer or composite than the rest of the riser, or from metal. A method for producing a riser for an archery bow includes the steps of introducing a polymeric composite into a mold from a first end of the mold to facilitate a particular orientation of components of the polymeric composite, molding the polymeric composite to produce a billet that approximates a net shape of the riser, and then machining the billet to the final shape of the riser.
Claims15
An archery bow, comprising:
- a riser having a first end surface and an opposing second end surface;
- a first limb having a first end and a second end, said first end of said first limb being attached to said first end surface of said riser;
- a second limb having a first end and a second end, said first end of said second limb being attached to said second end surface of said riser;
- and
- a string connected between said second end of said first limb and said second end of said second limb;
- and
- said riser being fabricated from a thermoplastic polymer formed to a desired shape and flexibility selected from the group consisting of high heat distortion thermoplastic polymers, very high heat distortion thermoplastic polymers, and combinations thereof;
- and
- wherein said first limb and said second limb comprise a thermoplastic composite layer disposed over a thermoset material.
