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.

Road spikes with improved characteristics and methods of deployment
The present invention relates to road spikes that can made of long fiber reinforced thermoplastics that, when deployed, are geometrically positioned to puncture or disable a tire. The spikes can be formed of a long fiber reinforced thermoplastic containing 10-70% long fibers by weight. Spikes of this material can be made as direct and/or alternative replacements for existing metal spikes or as unique integrated devices. One integrated component is a device having several piercing elements that are deployed in a vertically divergent manner spaced about a vertical axis wherein at least one piercing element is directed towards the direction of the oncoming vehicle. In one embodiment deployable from a string, this is accomplished through the use of spikes with six piercing elements that are self-leveling and self-centering. In another embodiment, several clusters can be fixed to a tube that is foldable and extendable.
