In a method for making a hybrid leaf spring at least one layer of composite material is provided and a metal primary leaf. The layer of composite material and metal primary leaf are positioned adjacent one another in a mold having an interior cavity defined by at least one cavity wall. A layer of adhesive material is located between and in engagement with the layer of composite material and the metal primary leaf. The adhesive is cured by controllably heating the metal primary leaf so that energy in the form of heat is conducted therefrom into the adhesive layer bonding said metal primary leaf and layer of composite material together.

In a method for making a hybrid leaf spring, at least one layer of composite material is molded onto a primary leaf using a mold with an interior cavity having a curvature for receiving the primary leaf at a depressed camber relative to its initial camber. The depressed camber is between unloaded and curb load cambers of the hybrid leaf spring. The primary leaf and the layer of composite material are positioned in the mold adjacent to one another and with a layer of adhesive therebetween. The layer of adhesive is cured for bonding together the primary leaf and the layer of composite material at the depressed camber so as to generally eliminate bond line shear stress when the camber of the hybrid leaf spring is at the curb height.

A hybrid leaf spring includes an elongated primary leaf having a compression surface, an opposite tension surface, and a first modulus of elasticity. At least one composite material layer is provided having a second modulus of elasticity different from the first modulus of elasticity. An adhesive layer is interposed between and bonds the at least one composite material layer to and in substantially parallel relationship with a respective one of the tension and compression surfaces of the elongated primary leaf. A reinforcing layer of natural, synthetic or metallic sheet material extends within the adhesive layer, preferably in spaced relation to opposing surfaces of the primary leaf and the composite material layer to strengthen the bond formed by the adhesive layer.

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.

A panel had a first face and a second face, including a strike face portion having a first plurality of plies each containing fibers in a matrix material. There is a support portion adjacent to the strike face portion, the support portion containing a second plurality of plies each having fibers in a matrix material. Each ply is bound to an adjacent ply and the first fibers are lower-performing relative to the second fibers. Protection from a ballistic threat may be provided by providing such a panel with the strike face disposed toward the threat. In another aspect, a composite ballistic panel may contain fibers in a thermoplastic matrix material, to the substantial exclusion of thermosetting matrix materials.

A product sheet of composite material can be made by disposing composite materials of composite material in adjacent (side-by-side) relation with each other. The composite materials comprise fibers in a thermoplastic matrix material. The adjacent composite materials are bonded together to provide a product sheet of composite material. Preferably, a cross ply of composite material is disposed on the composite materials. The cross ply may be a unidirectional sheet and the fibers in the cross ply may be disposed in transverse relation to the fibers in the composite materials.

A composite laminate is made by providing at least a first composite ply and a second composite ply, each having longitudinally oriented fibers in a thermoplastic matrix. The second composite ply is disposed on, and in transverse relation to, the first composite ply. Preferably, the second ply is disposed at 90 relative to the first ply. An article can be manufactured by providing a core material and applying a reinforcing material to a portion of the core material. The reinforcing material is a reinforcing composite ply or a composite laminate as described herein. Optionally, the core material is a prepreg that may be a composite laminate.
