    摘要： The present invention relates to a three dimensionally fiber-reinforced riser and to the unitary or single-step methods of making the same. In one embodiment (a cross bow riser for example), the riser has an interior support with opposed side members and a front brace. The front brace has a depression centrally located therein. Two side ribs are also provided for structural support. Two pockets each optionally having a divider wall defining a top and bottom section are provided for receiving respective top and bottom pieces of a split limb, when a split limb is used. The riser can be made of a composite material having fibers aligned there within in the directions of the highest stresses for enhancing the structural strength of the riser. Other bow parts or components can likewise be made via composite material as well.

    摘要： A composite string such as a bowstring or cable used in archery bows and crossbows includes multiple types of strands or multiple types of materials in its strands. The different materials or strands have different properties such as stiffness, strength, abrasion resistance, or density. The string therefore has specialized properties such as different properties when subjected to different tensile loads or optimized durability. A serving material is also used to bind strands of material to the string for silencing, vibration dampening, improving durability, or providing additional rigidity to select portions of the string.

    摘要： A crossbow may include a crossbow barrel having reduced weight and increased strength and shock resistance to the crossbow. This invention may also aid in improving torsional resistance, improving specific stiffness, and increasing compresses strength. The invention may also reduce friction between a barrel and a bow string to increase bow string life. The invention may also reduce the friction between a barrel and a bow to allow added arrow distance. Additionally, the crossbow may decrease both vibration and sound.
