Surface micro-texturing has been proven an effective way to reduce friction and wear for tribological applications. There is provided a low cost hot sintering method to apply micro-texturing on an advanced bearing polymer material. First, one face of the mold was micro-textured using a micro-casting method. Second, the cured Aromatic Thermosetting coPolyester (ATSP) powder was filled in the mold. Next, the filled mold was placed in a hot press for a hot sintering process. Finally, the textured bulk ATSP was cooled. The micro-textured ATSP bulk material was machined and compared with plain untextured material. The micro-textured material could effectively reduce friction at speeds lower than 2.46 m/s: 14% reduction in average.

The present invention is a unique process of manufacturing rigid members with precise “shape keeping” properties and with reflective properties pertaining to radio frequency energy, so that air, land, sea and space devices or vehicles may be constructed including parabolic reflectors formed without discrete permanent layering. Rather, such parabolic reflectors or similarly, vehicles, may be formed by homogeneous construction where discrete layering is absent, and where energy reflectivity or scattering characteristics are embedded within the homogeneous mixture of carbon nanotubes and associated graphite powders and epoxy, resins and hardeners. The mixture of carbon graphite nanofiber and carbon nanotubes generates higher electrode conductivity and magnetized attraction through molecular polarization. In effect, the rigid members may be tuned based on the application. The combination of these materials creates a unique matrix that is then set in a memory form at a specific temperature, and then applied to various materials through a series of multiple layers, resulting in unparalleled strength and durability.

Crumb rubber obtained from recycled tires is subjected to an interlinked substitution process. The process utilizes a reactive component that interferes with sulfur bonds. The resulting treated rubber exhibits properties similar to those of the virgin composite rubber structure prior to being granulated, and is suitable for use in fabricating new tires, engineered rubber articles, and asphalt rubber for use in waterproofing and paving applications.
