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 said mold to facilitate a particular orientation of components of said 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.
Claims7
