    • Free fibers (10) are deposited on a rotary support turntable (30) by means of a hollow deposition cone (40) having an outer wall surrounding a chamber and pierced by multiple perforations. The fibers are delivered to the outer surface of the perforated wall of the cone (40) in a cone feed zone that is remote from the zone for deposition on the turntable (30), and they are then held by suction being established inside the chamber, leading to suction through the perforations in the cone, so as to be transported by rotation of the cone from the cone feed zone to the zone for deposition on the turntable, and the fibers cease to be held on the cone in the deposition zone by localized interruption of the suction through the perforations in the wall of the cone, at least in said zone, such that the transported fibers are deposited on the turntable which is rotated about its own axis simultaneously with the cone being rotated. The fibers deposited on the rotary turntable (30) may be compacted and needled.
    • 游离纤维(10)通过中空沉积锥体(40)沉积在旋转支撑转盘(30)上,中空沉积锥体(40)具有包围室的外壁并被多个穿孔刺穿。 纤维在远离用于沉积在转盘(30)上的区域的锥形进给区域中被递送到锥体(40)的穿孔壁的外表面,然后通过在室内的吸力来保持它们 ,导致通过锥体中的穿孔进行抽吸,以便通过锥体从锥形进给区域的旋转运送到用于沉积在转台上的区域,并且纤维在该沉积区域中停止保持在锥体上。 至少在所述区域中通过锥体的壁中的穿孔局部地中断抽吸,使得所输送的纤维沉积在转盘上,该转台在锥体旋转的同时绕其自身的轴线旋转。 沉积在旋转转台(30)上的纤维可以被压实和针刺。

    • The present invention provides a carbon-carbon composite material consisting of a matrix carbon and a fibrous reinforcing carbon, said matrix carbon and fibrous carbon consisting substantially of amorphous carbon and forming an interface without an intervening third material, wherein said composite material has a fracture surface showing a uniform vitreous light reflection, but when it is used as an anode and electrolytically etched in sulfuric acid-acidified water, a difference in the degree of etching arises between the matrix carbon and the fibrous carbon, and a method for the preparation thereof. The composite material has a high flexural strength and a very low gas permeability and is useful as a molding material in the fields of high temperature chemistry, the atomic energy industry and medicine.
    • 本发明提供一种由基体碳和纤维增强碳组成的碳 - 碳复合材料,所述基体碳和纤维状碳基本上由无定形碳组成,并形成界面而没有中间的第三种材料,其中所述复合材料具有断裂面 显示均匀的玻璃光反射,但是当其用作阳极并在硫酸酸化的水中电解蚀刻时,基质碳和纤维状碳之间的蚀刻程度的差异及其制备方法。 该复合材料具有高的弯曲强度和非常低的透气性,并且可用作高温化学,原子能工业和医药领域的成型材料。
