A prosthesis for a synovial joint arthroplasty within a human body is provided. The prosthesis includes a first prosthetic component, the first prosthetic component including a first surface and the first prosthetic component is formed of a plastic compound, the plastic compound includes a polymer, a plurality of long glass fibers, the long glass fibers being randomly dispersed throughout the polymer to improve surface fatigue life and inhibit surface crack propagation to the prosthesis and improve wear resistance of the prosthesis, a number of the plurality of long glass fibers configured to protrude outward from the first surface of the first prosthetic component, a plurality of beads, the beads being randomly dispersed throughout the polymer to improve surface fatigue life and inhibit surface crack propagation to the prosthesis and improve wear resistance of the prosthesis, a number of the plurality of beads configured to protrude outward from the first surface of the first prosthetic component, a second prosthetic component, the second prosthetic component including a second surface, the second surface of the second prosthetic component configured to engage said first surface of said first prosthetic component and slide relative to the first surface of the first prosthetic component while contacting the plurality of long glass fibers protruding outward from the first surface of the first prosthetic component and the plurality of beads protruding outward from the first surface of the first prosthetic component.
