the of characteristics Carbon / carbon composite brake

Carbon / carbon composite brake disk ring preform weaving. Used preform orthogonal weaving vertical trend of long fibers in each layer, after forming a square, then cut into a round ring. Material utilization is low. The purpose of this invention is to develop a manufacture of the Carbon / carbon preform of the composite brake disk ring weaving method. By the cell layer in the α layers followed by 10 ° to 85 ° angle between the rotation angle, the upper and lower composite overlay laying repeated vertical acupuncture, pressure is made density of 0.5 to 0.58 g / cm 2, the inner diameter of 200 to 300 mm, outside diameter of 500 to 600 mm and a height of 30 to 36 mm circular preform. The advantage is to improve the quality of utilization of raw materials and processed products, while using non-orthogonal arrangement of the long fibers, to achieve the consistency of the mechanical properties to improve the service life and overall performance of the carbon brakes.
