CRUCIBLE HOLDING MEMBER AND METHOD FOR PRODUCING THE SAME

摘要

A crucible holding support member and a manufacturing method thereof are provided to secure the shape stability and high intensity by bundling a plurality of carbon fibers. The matrix is filled in a gap between the carbon fibers. A plurality of first strands(22A) is arranged to the first direction about the central axis to the first angle. A plurality of secondary strands(22B) is aligned to backward about the central axis to the same second angle as the first angle. A hollow mesh body(20) of hollow comprises a plurality of longitudinal direction strands(22) aligned within the same side as the central axis. A hollow mesh body(20) has the cylindrical shape of the hollow which is opened up and down. The bottom part of the quartz crucible is supported by the caldera shaped part formed on the upper side of support.
