    • Apparatus for producing refractory material filaments comprises an enclosure (11), means for heating the constituents of the refractory material, non-contacting means to support a drop (17) of molten material such as silicon, being one of the constituents of the refractory material within the enclosure and means to transport a filament (10) such as carbon, being a second constituent of the refractory material, through the drop of molten material in use. A levitation coil and/or an inert gas jet is used to support the drop of molten material and a silica glass or other refractory tube (13) is used to direct the gas jet. The enclosure has opposed side arms (15, 16) respectively for entry and exit of the filament (10) or the filament may be passed vertically through the molten silicon drop. An inclined side tube may be provided through which grains of silicon may be introduced into the enclosure for addition to the molten drop. In one form, initial heating of the silicon prior to levitation is achieved by providing a resistively heated silicon nitride platform on which the silicon is melted, the platform then being moved from the field of the levitation coil to leave a levitated silicon drop.

    • A fiber bundle (B) workpiece is coated with a particulate material during passage about a plurality of pulleys (54, 56) arranged to establish a serpentine travel path portion through a coating zone (10). The pulleys have arcuate grooves (58) extending thereabout, which cause the fiber bundle to twist axially, and the fibers of the bundle move with respect to one another as the fiber bundle moves along the serpentine path. These two actions increase coating efficiency and the penetration of particulate material into the fiber bundle. The travel path portion will preferably lie in horizontal plane, and the coating means will normally constitute an electrostatic fluidized bed of particulate material. After exiting the coating zone, the fiber bundle may pass through an oven (12) to partially melt the particulate material, and thereby cause the particles to adhesively attach to the fiber bundle. The fiber bundle, with particulate material attached thereto, may thereafter be collected and stored on a spool (32) as an intermediate product for use in subsequent composite article manufacturing processes.
    • 纤维束(B)工件在通过多个带轮(54,56)的通路期间涂覆有颗粒材料,所述多个带轮布置成通过涂覆区域(10)建立蛇形行进路径部分。 滑轮具有在其周围延伸的弓形凹槽(58),这导致纤维束轴向扭转,并且当纤维束沿着蛇形路径移动时,束的纤维相对于彼此移动。 这两个动作增加了涂层效率和颗粒材料渗透到纤维束中。 行进路径部分优选地位于水平面中,并且涂覆装置通常构成颗粒材料的静电流化床。 在离开涂层区域之后,纤维束可以通过烘箱(12)以部分地熔化颗粒材料,从而使颗粒粘附到纤维束上。 随后将附着有颗粒材料的纤维束收集并存储在作为后续复合制品制造工艺的中间产品的卷轴(32)上。
