  • Patent number: 7211208
    Abstract: A method and apparatus for making carbon/carbon composite disks for braking applications that employs a continuous feeding of fiber strands into a mold. The fibers are then compressed to form a mat or preform. The fibers are then needled such that the fibers within the mat interlock and extend in various directions. The mat or preform is then subjected to densification processing. In order to enhance the effectiveness of the densification process and/or to speed up the processing time, a filler is added to the preform during the manufacturing process. The fillers are added by way of a dry powder or as a liquid slurry. The filler may be aluminum oxide, boron carbide, silicon carbide, pitch, or a variety of carbonic or noncarbonic performance enhancers.

  • Patent number: 5133211
    Abstract: A dynamic wheel bearing test system employs a motor and fly wheel interconnected through a drive shaft and clutch or speed control with a wheel portion mounted upon a fixed axle with test bearings interposed therebetween. The drive shaft is received by and rotates within a load reaction block to which are connected hydraulic actuators operating in three orthogonal planes to impart loads to the bearings. A first set of actuators provides radial loads to the bearings, a second provides side loading of the bearings, while a third set of actuators simulates a drag upon the aircraft employing the wheel and bearings under test.
