摘要: Novel composite orthopedic devices with modulus variations are disclosed. The device contains an extraosseous portion attached to a first intraosseous portion which is secured to a second intraosseous portion; the intraosseous portions may interface with the intramedullary canal of the human femur. The modulus varies along the length of the device, decreasing from the extraosseous portion to the second intraosseous portion. The variations in modulus are achieved by forming the device from a composite comprising filaments nonlinearly disposed about the longitudinal axes of the device and within a polymer matrix. The method of making the present orthopedic device is also disclosed.

摘要: A thickness control system for controlling the thickness of an extrudate includes a nested temperature control loop for controlling the temperature of a heat responsive element based upon a predetermined temperature set point. The temperature set point for the temperature control loop is computed based upon the measured thickness of the extrudate.
